One thing on your RAM vs core discussion: L3 cache requirements scale non-linearly with core counts thanks to the increased incidence of L2 cache misses.
That's why the chip architecture is critical with more and more cores. AMD, Intel, and Ampere all seem to take slightly different approaches. I've enjoyed some of the ChipsandCheese articles on these new architectures!
@@shanent5793 It's non-linear and there's an exact formula. Let's say you have a 5% chance of a cache miss per core, so a 95% chance of a cache hit. The percentage chance of a cache miss with N cores is (1 - (.95^N)) * 100. Obviously the chance of a miss - that 5% - is dependent upon the workload. The more misses you have, the greater the pressure. And the fewer the RAM channels you have the greater the effect of L3 cache misses.
@@QuentinStephens that's just the chance of at least one miss. Multiple misses will have binomial probabilities so their sum converges to linear. 128 cores are expected to have twice as many misses in total vs. 64 cores. Either way more cores causes more L3 pressure so why does the Ampère only have 16MB which is less than desktop CPUs with only 6 cores or 12 threads?
@@shanent5793 I'm not sure you're correct about the binomiality but yes, I do agree that the 16 MB cache does seem rather low, especially when we have Epyc CPUs with 1 GB cache for similar numbers of cores.

We're finally returning to the RAM situation we had a decade ago, where workstation motherboards had lots of RAM slots. My (now very old) super micro x8dah+-f board has 18 (9 per CPU). IMO, the biggest problem with modern processors is the extremely limited PCI-e lanes available. Look at chip specs over the years, and it's something that has steadily decreased. With Thunderbolt and NVME, PCIe lanes are the most limiting feature on all my computers - even laptops.
Yeah; I have run into that on my Ryzen 7000 series desktop, there are few motherboards that even expose the lanes in a way I can fully utilize them :( The nice thing with this Ampere chip is it has 128 lanes, and almost all are usable on this motherboard! Still always want more, for more IO :)
Still run a 4790k on my seedbox due to this. Haven't found a non-server mobo with 10 on-board sata slots for spinning drives since that generation for any other CPU I bought.
128 PCIe 4.0 lanes is plenty; that's 512 GB/s, more than enough to saturate 6 channels of DDR-3200 with only 154 GB/s half-duplex bandwidth. It's up to the motherboard or backplane designer to allocate them
The issue is that the PCIe lanes are used for M.2 slots and other onboard functions that didn't exist on boards 12 years ago. Back then those PCIe lanes mostly went to actual PCI slots.
@@arof7605My 4790k was a beast-even though I was never able to overclock it, it ran my main computer for over half a decade, and its core performance was *never* the bottleneck. But I'm surprised you're still using it-how do you live with a mere 32GB of RAM? (asked half-jokingly)
Something to note about NVIDIA's ARM binary drivers: they have driver library files for x86-64 and aarch64, but they don't have armhf driver libs for software running under box86. That is, box86 converts 32-bit Intel into 32-bit ARM, not into 64-bit ARM. For i386 games, you'd likely need to use an AMD GPU -- Polaris (RX5xx) or older. One game I find very useful for checking the performance of GPUs on ARM is Veloren. It uses Metal on MacOS, Vulkan on Linux, and Vulkan or DX12 on Windows (though there's no ARM Windows build).

Really cool. Btw Jeff I found a way easier way to connect LTE modems via, Modem Manager and Network Manager. No need to install QMI libraries, they're already in Debian 12.
Hey Jeff, running the bedrock edition, especially the mobile version as you did, is a far too easy challenge for your rig. I suggest running and comparing the latest java version and a specific modded version: Faboulously Optimized. To get any architecture incompatibilities out of the way, consider using a launcher that comes as a JAR file, such as the Technic launcher Make sure to use the latest jre (20-21) and set the proper JVM flags Additional bonuses: shaders, resource pack with parallax mapping + physics mod pro (then grab a fire extinguisher) Looking forward to hearing from you!
I admire it so much that you are able to work around such unusual circumstances. I can't even get a Linux graphics driver fully working in an ideal setup.
@@robkam643400 I understand why you would want to buy AMD gpu for linux, but what's the point of swapping Intel CPU for AMD one?(unless you mean Intel ME, but it's works the same with with Windows)
It sounds like the real bottleneck here is DDR5 support. Which is supported by the upcoming Ampere revision. Which is even faster. This is a surprisingly effective workstation for a development board, and further software support should improve it even further. I could see Blackmagic integrating one with a pile of their PCIe cards to build a behemoth video switching workstation capable of real-time effects - and driver support is a lot easier when you make the cards!
Nice. They really make amazing stuff. Too bad I can't afford it. Would love an Ampere workstation so much. But I'm happy with RK3588 and my pc when I need it.
Could you try spinning up hundreds or (thousands?!?) of docker containers with Kubernetes? With all those CPU cores it's gotta be really fast to ramp up the instances.
Thats what its in part for. However like Jeff was saying, you do run into memory bandwidth limitations, meaning that per core you can't expect linear performance curve based on the number of cores you have. I have an expectation that a lot of customers who are running off the shelf applications will probably benefit more from the lower core sku but if you design your application around the server the 128 core will probably be worth it.
@@MegabeanI used to have a workload that was shared-nothing, buffered data by thread, was computationally heavy, had fairly small unit sizes of data (commonly
@@thewiirocks Thats cool, sadly not enough background to fully understand. I do 3D rendering though, I use a java application called Chunky, it's a voxal type renderer (might be using the wrong term). It does photorealistic rendering. I've been able to saturate my server with it, with 64 cores and 128 threads. Idk how much memory plays into it, outside it as using every bit of memory you allocate to it.
@@Megabeanthe biggest thing you need to consider for memory is how long you're keeping data in the L1 and L2 caches, and whether or not you're unnecessarily evicting data and then asking for it back. A very common pattern in modern software is to perform one operation at a time (e.g. an addition of two values) across a large collection of data, looping over the data separately for each operation. This is _terrible_ for the cache as the CPU is forced to evict each record to make room for the next record in the collection, thereby reducing your throughput to the memory bandwidth and making your caches useless. This can be hard to detect as test data sets tend to be small enough to fit within L3 and therefore exceed memory bandwidth. It's only once the data sizes are scaled that the true limits of the memory bandwidth are hit. Worse yet, the CPU will look busy to the operating system even though it's spending most of its time doing nothing. What you really want to do is to bring in a record of data, perform all operations you possible can on it, then be done with it for that computational cycle. That maximizes the amount of time a record can be held in CPU caches. If done correctly you may be able to operate entirely out of the L1 cache, which can easily provide an order of magnitude performance improvement.
Nice video! Almost getting one myself! Is it the 2,8Ghz version of the CPU Ampere will ship? Regarding the Mac, let’s not forget M2 Max and M3 Max have tremendous memory bandwidth, 400GB/s.. quite much more so than a DDR4 system I believe. That makes them maybe faster in memory bandwidth limited problems, such as several types of simulations etc with low flops per byte ratio. AmpereOne has the DDR5 memory system support. However, I have not seen it easily available like this CPU is. With only 3 out of 4 memory channels being connected, maybe the 96 core version is a “better fit” as the amount of bandwidth per core will be quite better, for anything bandwith sensitive that is.
Bandwidth not keeping up with compute power has long been an issue. One amusing statistic is that standard floppy disks are faster than a typical NVMe drive (compared to capacity). You can read a 1440k floppy in about 45 seconds but a Samsung 990 PRO 2TB will take over 4 and a half minutes. Even the IOPS per megabyte is a bit faster on the floppy. With a slow step rate of 8ms you'd have a worst case of 840ms access time or .82 IOPS/MB. The 980 is 1.4 million IOPS best case which comes out to 0.7 IOPS/MB.
Upgraded my laptop's monitor to 4K and with 100% scaling I can read the text on your screen at 0:55 With any other scaling the text becomes more blurry and if I right click on the video and click stats for nerds, the resolution of the viewport changes with the scaling. Also, on my win 10 laptop I can't just hover over the speaker icon in the taskbar and scroll to change the volume, which win 11 does. Sorry for the unrelated comment but hey, good to see you are doing well and are in good health!
For at least one of those games, the text console had an error message about "out of thread IDs". Presumably it's trying to spin up one thread per core or per SMT. If you can artificially limit the number of cores that the OS sees, or that it shows to userspace programs, you might have a shot at getting these to work... Does ARM have SMT? Turning that off would be interesting too.
First time watcher, awesome video so far! Subd ofc. There was this guy that printed custom ducting for his fans directly over the cpu etc. Got good results. Oh and a guy that cooled with dry ice and got 0°c. For someone who doesn't know about computers, does that mean you can run it all infinitely fast lol?
I would try it on Fedora, which has vanilla and almost edge Linux kernel, plus they have proper nvidia support with wayland now, and with its special ram config (which requires no swap now). Things might run better. And I always use the flatpak version of steam, runs quite good
1.3TFLOPS is at least double what the RTX 4070 Ti can do. The CPU can access much more memory with lower latency so there's no comparison. "Ti" is an abbreviation of "Titan" so it's pronounced like the first syllable. Titan never made sense anyways because the Titans lost to the Olympians, so Ti was just a face-saving compromise. The company is still named after one of the seven deadly sins, which shows that they can't let go of something that sounds cool
Are you sure you are not just citing the effect of the abysmal FP64 performance of the card? A 4070 Ti really ought to be able to do much better than 1.3 in single-precision aka. FP32. The CPU would also be faster but only by a factor of 2x, but I would expect at least ~6 TFLOPS from the 4070 Ti in FP32.
@@TheBackyardChemist Compute TFLOPS is traditionally FP64. Ada has a 1:64 FP32/64 ratio so it's around 40 TFLOPS FP32 on the GPU. You could emulate 64 bit math and get the ratio down to 1:4 but it's not IEEE compliant. CPUs should be 1:2 but they run into power limits and drop the clock speed if it's too much work. Of course these are all peak theoretical figures, branching code and sparse access won't allow the GPU to reach its maximum performance

I just saw this, but Minecraft Java runs on ARM, with shader support-just use Prism Launcher, and you’ll need to install a specific ARM JDK version for the version of Minecraft you intend to run. The entire process is identical to using Prism Launcher in any OS on any CPU, and there are many guides on how to do it. I highly recommend when you create an instance, rather than choosing a vanilla game, go straight to the mods page, and search for and select “fabulously optimized” from the mod search menu. Then you’ll want to install Iris, and then go to the resource packs tab and search for shaders
The key difference of M2 ultra is that 192 GB ram is also VRAM which makes it possible to run some 180B LLMs on it which is not possible for other consumer level PC.
If they use 192gb of vram what cpu will use air or water? I m prety confident that those workloads it wont be run on mac mostly. There s no way that in RL vram can access 192gb in a mac. I qoute what a teacher of a famous university said. " the more advanced is your jobs the less mac you will see"
Hello. How about using it as a web server and virtualization (ESXi and windows server with hyper-v)? Can you do some tests for these? and maybe compare with some xeon processors? how fast mysql is on those cpus?

Thanks for sharing this with us, Jeff! I wasn't really aware just how compatible things were with ARM on Linux. I have to admit though, the LLM performance was actually rather poor. A used RTX 3090 (maybe $750?) could run that llama 2 13b model at 10x the inference speed. I'll be very interested once the GPU support with ARM is worked out as that seems like the main issue.
2:49 That RAM cannot keep up is not only the case for server CPUs. Even for these super fast data-center GPUs, 2TB/s VRAM bandwidth cannot keep up, because compute Tflops is still so much larger. They could cut the GPU die size in half and the software would still perform thr same. Nearly all compute software is bandwidth-bound nowadays.
I'm really wanting on arm to finally come to the desktop scene, especially for gaming and some lite office work or programming. I switched from x86 laptop to base model m1 mba and I'm so impressed with the power efficiency and battery life, got me through a huge machine learning project. Too bad apple hates their users and we'll have to wait for someone with more sense to come to desktop market with arm computers that can compete with Apple Silicon

@@lucasrem I despise the hustle and bustle of big city life.

@@lucasrem we're not talking about perfromance, only core count, IIRC when i built my 12 core dual processor Xeon X5690 desktop the current-at-the-time version of cinebench only supported 16 threads, not 24
I wish I had a local Micro Center…
This is soooo cool! I can definitely use this for my MS Excel worksheets!
Great stuff, thank you, Jeff!
Thermal Paste: Forget what LTT says, its a physical junction that transfers heat, the larger the contact the more heat can move across it.
So you are completely right to spread the thermal paste out. Physics!
Great video an components and benchmark. Looks like you also have a lots data on DIMMs and waiting for a new video on them too.
We'll see; right now most of the data is spread across some GitHub issues. I may do at least a blog post on it at some point.
Good video. Easy to understand information.
Really cool. Btw Jeff I found a way easier way to connect LTE modems via, Modem Manager and Network Manager. No need to install QMI libraries, they're already in Debian 12.
Awesome video! ARM is a fascinating architecture, I cant wait to see where it goes in the near future!
Hey Jeff, running the bedrock edition, especially the mobile version as you did, is a far too easy challenge for your rig.
I suggest running and comparing the latest java version and a specific modded version: Faboulously Optimized.
To get any architecture incompatibilities out of the way, consider using a launcher that comes as a JAR file, such as the Technic launcher
Make sure to use the latest jre (20-21) and set the proper JVM flags
Additional bonuses: shaders, resource pack with parallax mapping + physics mod pro (then grab a fire extinguisher)
Looking forward to hearing from you!
HELL of a video Jeff !
I'm ready for (another) ARM desktop!
Really amazing, did not know that there are already ampere cpu workstation in the field!
What I learned here .... Its Amazing but still not work yet!!!! Great job BTW! I loved this video!!
O yaaaa! Micro Center... Inconveniently located for 90% of ALL OF US!
I admire it so much that you are able to work around such unusual circumstances. I can't even get a Linux graphics driver fully working in an ideal setup.
Just buy hardware for linux, instead of the other way around.
Buy all AMD. It'll all work out of the box if it's over a year or so old.
@@robkam643400 I understand why you would want to buy AMD gpu for linux, but what's the point of swapping Intel CPU for AMD one?(unless you mean Intel ME, but it's works the same with with Windows)
It sounds like the real bottleneck here is DDR5 support. Which is supported by the upcoming Ampere revision.
Which is even faster.
This is a surprisingly effective workstation for a development board, and further software support should improve it even further. I could see Blackmagic integrating one with a pile of their PCIe cards to build a behemoth video switching workstation capable of real-time effects - and driver support is a lot easier when you make the cards!
jrshaul
What DDR u used, Ampere ?
ARM is not needing more than 6000 DDR 5 !
Dang. Getting a type 1 hypervisor on that thing would be SWEEEEET
Just went to micro center yesterday to pick up the EVA asus parts. Love seeing my hometown micro center here, STL rep!
Very informative, thanks!
I tried box 86 and 64 a Long time ago:-/
It’s nice to see someone else having better luck
Nice. They really make amazing stuff. Too bad I can't afford it. Would love an Ampere workstation so much. But I'm happy with RK3588 and my pc when I need it.
Awesome content as always!!!!
damn one of my dream server thank you to review it Jeff
I really miss living near a Micro Center. They really is the best PC store I've ever been to. Please come to the PNW!
Yeah, wish there was a Micro Center near Seattle.
One large advantage to the Apple RAM is that it's unified, meaning you essentially have 192GBs of VRAM, which is useful for machine learning tasks.
Exacto
192 gb of ram for gpu and cpu will use air for working?
9:30 this makes me disproportionally happy as a linux fanboy. finally the tables have turned.
Could you try spinning up hundreds or (thousands?!?) of docker containers with Kubernetes? With all those CPU cores it's gotta be really fast to ramp up the instances.
Thats what its in part for. However like Jeff was saying, you do run into memory bandwidth limitations, meaning that per core you can't expect linear performance curve based on the number of cores you have. I have an expectation that a lot of customers who are running off the shelf applications will probably benefit more from the lower core sku but if you design your application around the server the 128 core will probably be worth it.
@@MegabeanI used to have a workload that was shared-nothing, buffered data by thread, was computationally heavy, had fairly small unit sizes of data (commonly
@@thewiirocks Thats cool, sadly not enough background to fully understand. I do 3D rendering though, I use a java application called Chunky, it's a voxal type renderer (might be using the wrong term). It does photorealistic rendering. I've been able to saturate my server with it, with 64 cores and 128 threads. Idk how much memory plays into it, outside it as using every bit of memory you allocate to it.
@@Megabeanthe biggest thing you need to consider for memory is how long you're keeping data in the L1 and L2 caches, and whether or not you're unnecessarily evicting data and then asking for it back.
A very common pattern in modern software is to perform one operation at a time (e.g. an addition of two values) across a large collection of data, looping over the data separately for each operation. This is _terrible_ for the cache as the CPU is forced to evict each record to make room for the next record in the collection, thereby reducing your throughput to the memory bandwidth and making your caches useless.
This can be hard to detect as test data sets tend to be small enough to fit within L3 and therefore exceed memory bandwidth. It's only once the data sizes are scaled that the true limits of the memory bandwidth are hit. Worse yet, the CPU will look busy to the operating system even though it's spending most of its time doing nothing.
What you really want to do is to bring in a record of data, perform all operations you possible can on it, then be done with it for that computational cycle. That maximizes the amount of time a record can be held in CPU caches. If done correctly you may be able to operate entirely out of the L1 cache, which can easily provide an order of magnitude performance improvement.

We approve your usage of SuperTuxKart!
The machine specs gives me the same feelings as when I saw and heard a monster truck performing in person for the first time! 🔥🤯
Nice video!
Almost getting one myself! Is it the 2,8Ghz version of the CPU Ampere will ship?
Regarding the Mac, let’s not forget M2 Max and M3 Max have tremendous memory bandwidth, 400GB/s.. quite much more so than a DDR4 system I believe. That makes them maybe faster in memory bandwidth limited problems, such as several types of simulations etc with low flops per byte ratio.
AmpereOne has the DDR5 memory system support. However, I have not seen it easily available like this CPU is.
With only 3 out of 4 memory channels being connected, maybe the 96 core version is a “better fit” as the amount of bandwidth per core will be quite better, for anything bandwith sensitive that is.
Bandwidth not keeping up with compute power has long been an issue. One amusing statistic is that standard floppy disks are faster than a typical NVMe drive (compared to capacity). You can read a 1440k floppy in about 45 seconds but a Samsung 990 PRO 2TB will take over 4 and a half minutes. Even the IOPS per megabyte is a bit faster on the floppy. With a slow step rate of 8ms you'd have a worst case of 840ms access time or .82 IOPS/MB. The 980 is 1.4 million IOPS best case which comes out to 0.7 IOPS/MB.
Upgraded my laptop's monitor to 4K and with 100% scaling I can read the text on your screen at 0:55
With any other scaling the text becomes more blurry and if I right click on the video and click stats for nerds, the resolution of the viewport changes with the scaling.
Also, on my win 10 laptop I can't just hover over the speaker icon in the taskbar and scroll to change the volume, which win 11 does.
Sorry for the unrelated comment but hey, good to see you are doing well and are in good health!
Awesome video. Thanks!
$99 for a decent 3D printer… Man, i wish i had Micro Centre in the UK
what do you still have ?
For at least one of those games, the text console had an error message about "out of thread IDs". Presumably it's trying to spin up one thread per core or per SMT. If you can artificially limit the number of cores that the OS sees, or that it shows to userspace programs, you might have a shot at getting these to work...
Does ARM have SMT? Turning that off would be interesting too.
First time watcher, awesome video so far! Subd ofc. There was this guy that printed custom ducting for his fans directly over the cpu etc. Got good results. Oh and a guy that cooled with dry ice and got 0°c. For someone who doesn't know about computers, does that mean you can run it all infinitely fast lol?
I would love to see proxmox with a Hackintouch VM on it.
Linux is killing it on ARM! Great video!!
I would try it on Fedora, which has vanilla and almost edge Linux kernel, plus they have proper nvidia support with wayland now, and with its special ram config (which requires no swap now). Things might run better. And I always use the flatpak version of steam, runs quite good
I would love to see a video/more information on the opensource LLM you used in this build. That looks super interesting.
That’s really cool! Imagine if we could a RISC-V CPU to game on Linux!
1.3TFLOPS is at least double what the RTX 4070 Ti can do. The CPU can access much more memory with lower latency so there's no comparison.
"Ti" is an abbreviation of "Titan" so it's pronounced like the first syllable. Titan never made sense anyways because the Titans lost to the Olympians, so Ti was just a face-saving compromise. The company is still named after one of the seven deadly sins, which shows that they can't let go of something that sounds cool
Are you sure you are not just citing the effect of the abysmal FP64 performance of the card? A 4070 Ti really ought to be able to do much better than 1.3 in single-precision aka. FP32. The CPU would also be faster but only by a factor of 2x, but I would expect at least ~6 TFLOPS from the 4070 Ti in FP32.
@@TheBackyardChemist Compute TFLOPS is traditionally FP64. Ada has a 1:64 FP32/64 ratio so it's around 40 TFLOPS FP32 on the GPU. You could emulate 64 bit math and get the ratio down to 1:4 but it's not IEEE compliant. CPUs should be 1:2 but they run into power limits and drop the clock speed if it's too much work. Of course these are all peak theoretical figures, branching code and sparse access won't allow the GPU to reach its maximum performance
I thought this gonna cost a kidney and a heart but the price is actually really good

1:18 Jeff, with all this power comes great responsibility. I can't believe you missed the low hanging fruit.
Next time!
@@JeffGeerling Very cool, I'll be watching for it. I almost bought one of these systems back when you showcased it but now that I've also become one of the masses without a job I'll hang onto the pennies and live vicariously through you!
@@vincei4252 Aww, I hope you will get back into gainful employment soon!
@@JeffGeerling Thanks man! I won't lie, retirement looks good too ☺
@@vincei4252Ha! Well then, finding some things that will keep the brain going!
to put your Cinebench 24 score into X86 context, a Intel i9 13900KS at 5.6ghz scores 2379 Multi and 142 single while a AMD 7950X3D at 4.5ghz scores 1829 multi and 111 single
single core is obviusly lacking on that 128 core, but the multicore for sure aint
It's one of those "well one ain't good enough, let's just throw ALL THE CORES in there" problems :)
I really want to see the single core specs on AmpereOne. Or see Apple create a 128 core monster M2 Ultra Ultra Supreme :D
@@JeffGeerling The upcoming revision supports DDR5. Assuming twice the memory bandwidth and adequate driver support, perhaps a 4K+ Cinebench score is in the cards?
I just saw this, but Minecraft Java runs on ARM, with shader support-just use Prism Launcher, and you’ll need to install a specific ARM JDK version for the version of Minecraft you intend to run. The entire process is identical to using Prism Launcher in any OS on any CPU, and there are many guides on how to do it.
I highly recommend when you create an instance, rather than choosing a vanilla game, go straight to the mods page, and search for and select “fabulously optimized” from the mod search menu. Then you’ll want to install Iris, and then go to the resource packs tab and search for shaders
The key difference of M2 ultra is that 192 GB ram is also VRAM which makes it possible to run some 180B LLMs on it which is not possible for other consumer level PC.
If they use 192gb of vram what cpu will use air or water?
I m prety confident that those workloads it wont be run on mac mostly.
There s no way that in RL vram can access 192gb in a mac.
I qoute what a teacher of a famous university said.
" the more advanced is your jobs the less mac you will see"
God I wish there was a microcenter near me
When your Microcenter is also Jeff Geerling's Microcenter....hey, did you leave anything for me Jeff?
Not *this* time!
Hello. How about using it as a web server and virtualization (ESXi and windows server with hyper-v)?
Can you do some tests for these? and maybe compare with some xeon processors? how fast mysql is on those cpus?
I really look at these ARM CPUs and i see they might change the servers world and i really think of getting an ARM server.
I’d like to see gaming evolve for ARM CPUs. Just to see where it goes
I'm running a VM on Hetzner that uses Ampere and it performs great for the price.
Thanks for sharing this with us, Jeff! I wasn't really aware just how compatible things were with ARM on Linux. I have to admit though, the LLM performance was actually rather poor. A used RTX 3090 (maybe $750?) could run that llama 2 13b model at 10x the inference speed. I'll be very interested once the GPU support with ARM is worked out as that seems like the main issue.
Yeah; honestly I think it just needs a little more twiddling and you could get GPUs to do the inference a bit faster.
5:32 Enjoy your air bubbles.
2:49 That RAM cannot keep up is not only the case for server CPUs. Even for these super fast data-center GPUs, 2TB/s VRAM bandwidth cannot keep up, because compute Tflops is still so much larger. They could cut the GPU die size in half and the software would still perform thr same. Nearly all compute software is bandwidth-bound nowadays.
Htop cores being like 5 chars wide is hilarious
Hoping to get an internship at Ampere. Thanks for bringing this company to my attention over the years
Looks like all the games that ran using Steam were made in Unity: Super Hot, Horizon Chase and Kerbal Space Program.
I'm really wanting on arm to finally come to the desktop scene, especially for gaming and some lite office work or programming. I switched from x86 laptop to base model m1 mba and I'm so impressed with the power efficiency and battery life, got me through a huge machine learning project. Too bad apple hates their users and we'll have to wait for someone with more sense to come to desktop market with arm computers that can compete with Apple Silicon
WOW. Increible proyecto. Podrias probarlo con la mineria de tokens para esa computadora..
Micro Center is the best! Great video.
Would be great to know if you eventually manage to get Llama to use the GPU on the ARM system.
Minecraft Java edition for linux (through an unofficial launcher) should run well on this beast (on the Nintendo Switch with Linux installed it is playable)
That's a lot of RAM! Holy cow!
Did you try manually setting the number of threads inside Cinebench? File menu, settings, put the tick in, set desired number of threads.
12:19 one of the problems you've likely ran into with Valve and halo games is anti-cheat, both VAC and Easy DO NOT like emulation, however WINE seems to have been made compatible lately, u guess to support the Steamdeck, which doesnt use emulation, just the proton translation layer, which the predecessor used to get you banned from CS:GO if i recall.
just curious did you try x265 cpu encoding? it gives nice quality for bitrate and you have the cores
The only problem with Microcenter is the lack of Microcenter; many folks are still stuck driving 3 hours plus to get to one, which is a hard sell over sitting on our bums at home and ordering like *snap*. Hopefully they ramp up their pace of opening new stores across the country, but only time will tell.
DeltaSierra426
Why move to rural America ? You did it yourself !
Microcenter you can do in big communities only !
@@lucasrem I despise the hustle and bustle of big city life. Less stress, better air quality, big yards (some have creeks, woods, etc. for hunting, fishing, recreation, gardening/farming, and so on), and in our area, a local telco invested in fiber-to-the-home, so tech life is still good; doesn't take much longer these days for etail shipping to these areas.
I actually live in a city of about 40,000. This provides the benefits of nearby shopping, food, jobs, etc. without being a monstrosity.
There are still plenty of big cities across the U.S. that don't have a Microcenter; I still stand by may statement that I'd like to see them expand more quickly. Even places like Austin, TX -- "the new silicon valley" (but they call it silicon hills) -- doesn't have a Microcenter and requires driving 4 hours to Dallas or 3 hours to Houston to get to one.
i pretty confident nvidia arm cpu gonna have built in x86 emulation hardware layer to run customize vkd3d-proton

they are not out yet, but those large new threadripper pros at 5gz look SWEET too (for sure over 5k per cpu tho)
I’m curious since the nvidia GPU wasn’t working with windows 11 but does work with Linux if using wsl ubuntu would help solve this?
yey u tested ksp! best game ever
Hello Jeff, why not video production? Davinci Resolve not yet compatible with Ampere?
Complaining that you can't use a dedicated/separate GPU with Apple Silicon but being OK with the fact that you can't use the same dedicated/separate GPU with Arm Windows is some pretty fun mental gymnastics.
Seems both Apple and Windows can't support pci gpu's on arm, but both CAN on x86... wow its almost like they're similar or something.
