Speed test G was the only test I actually thought was an actual speed comparison that is not total BS. Pls keep it alive
Is speed test G dead? This year there where no snap 8 gen 1, exynos 2200 and mediatek 9000 tests... it is a pity you did a great job in spreading information
Unfortunately it wasn't as popular as I had hoped.
Well Garry it was for some of us. If possible can you try with 8gen1 atleast for most popular phones@@GaryExplains
phones cost unless manufacturer send him testing units I hardly see viable for him to buy those with his own money he is not LTT unfortunately from a resource pov.
It is a pity Gary, the speedtest G was truly a good thing and I was onboard with it since day 0, I hope Gary Explains grows and maybe you will be able to get some devices from the manufacturers.
Thank you for repling, hopefully it is just a temporary goodbye to speed test F
SpeedTestG channel videos generate more views on average than the videos on this channel and the videos are quite easy to make too. It was pretty popular and had a dedicated base of viewers. Not too sure about this arguement.
Speed Test G faced some problems that have to do with animation handling on cross-app-transitions between ios and android (this continued to distort the results increasingly), i think this might be another big factor. Maybe gary is working on something in the background to bring speed test g back in the future.
@@manulovesjesus well the base of viewers although dedicated is not profitable enough. Doing an s21 ultra snap vs exynos costs him basically 3000 euros which I hardly see him get back from the video
Thanks Gary! I've been checking my subscriptions every day for the past month or so waiting for this video.
Meanwhile Qualcomm's most selling SoC Snapdragon 680 with Cortex-A73. Real progress.
I wish every High end and mid range processor to come with ARM V.9 architecture only.
how will the new arm cortex x3 enabled mobile processors stack up against the Apple A15 Bionic
@@Syed-wj4pj A15 will also use X3 probably .
u know that apple A chips are also arm chips? right?
Since A715 drops 32 bit support it's a no go for me since I still play some really old forgotten Android games
Thanks for the fantastic content Gary! I hope you know it is very much appreciated
Thank you Gary for always great content! Keep up the awesome!
Been waiting for this !! 🙌
Bring back speed test G
It doesn’t generate enough interest and views to support Those tests unfortunately.
I like that you talk about all the complicated things in a simple way What do I need to learn to go deeper into these things and become like you?
EEE
Since its almost impossible to get a Raspberry Pi where I live today. Especially since they are back order to 2023. I really wish somebody would create more SBC's that would support newer ARM architecture, like the X3, or A715. I would also love to see a 12 core ARM 9 SBC that is linux compatible.
Nvidia's Jetson platform is a good alternative to Pi and come with newer CPU designs. However they are more expensive.
why do you think they would have better delivery than the RPF? they are just as dependent on market forces as the RPF. If there is one company that can create better stuff with these new CPU's it would be the RPF themselves.
Nvidia is way bigger than the RPF.
Rpi would not use these high end chips though right. They are always on slightely older processors to be able to keep the low prices.
I would like to see some Raspberry priced SBC using older Snapdragons, say.
Not likely to happen in the forseeable future. ARM wants to maintain extremely high profits ($2.7 billion) for its high end architecture for mobile phones. So they certainly not going to risk that by releasing the same chips for a $200 SBC. You are better of with a Intel N6005 rather than RK3588 for example. The intel not only cheaper and faster. It already has working graphic drivers in ubuntu. Power consumption at idle 7.1 watts etc etc. Hopefully one day risc-v will mature. Until then I personally am not going to reward ARM's greed.
25 to 30% improvement is really really good. Haven't seen such a good jump in performance since a long time in Arm.
@Garrus Vakarian 80% behind what x86?
80 percent behind.
Baring the fact that arm processors are the most prevelant in the world by a huge margin, 20 billion chips a year, blowing AMD Intel and IBM combined out of the water.
You really should look more, ARM are world leaders, they have no rivals and no peers
80% faster? Where are you getting that number from? They are faster, that isn't in dispute, but 80%?
@Garrus Vakarian They dont use ARMS own design, Apple lisence the Core IP and thats it, they bake there own extra stuff into them, ARM Based is marketing wank, they dont feature the full arm instruction set either. Custom silicone and ARM are 2 very diffrent things. Intel CPUs have an ARM processor in them, come to think of it so do AMD, Snapdragonm QualComm, IBM, the list goes on and on and on, chances are your diswasher has an ARM CPU
@Garrus Vakarian You can't compare the speed of a smartphone to that of a laptop. The thermals are different, the power budget, the clock speeds, etc. 🤦♂️
RIP SpeedTest G
But I'm still positive 😌
So what configuration of an hypothetical Arm based desktop SoC would be on a level to let's say AMD 5600G or whatever Intel has the closest ( taking in account both cpu and gpu perf)?
Gary, we are still waiting for Speed test G videos for newer mobile SOCs like 8G1.
Speed Test G is on pause the moment as it wasn't as popular as I had hoped.
@@GaryExplains Speedtest G has a very big fan base. Pls bring it back!!
@Noobwreckspros Fps Thanks for your encouragement, but it is because Speed Test G DIDN'T have very big fan base that I have had to make it a lower priority.
14:11
Isn't that something similar to what you explained in your Apple processor videos?
What about auto overclocking entire SoC and multithreading per core like Hypertheading and SMT?
does it make sense to make a video about the CPU architecture of x3 and m1?
@Gary, where is your speed test G videos ?
Things went south with the app or you guys(AA Team) expected some sponsorship from the brands and didn't get it. So, dropped the project ?
WHatever it is, I miss the speed test very much. If possible please make it come back.
It wasn't as popular as I had hoped.
@@GaryExplains I agree, the app had great potential. There was no way of cheating it, specially the mediatek SoCs recently are rendering the games lower than it should inn the background to present it better in naked eyes.
Anyway, I thought Speed Test G might become very popular but when I saw nothing like that happening then I was disappointed and shocked.
May be, a different marketing or advertising strategy do the trick.
I am really hoping it will make a comeback.🤞🤞🤞
12 cores with if it is possible two imortalis GPU's would be a very nice Linux tablet to use
You will never see that 12 cores in tablets, since they are have 8 cores what alone can draw 4-5W power, so it can hit the 40-60W power consumption in total, so it's definitely requires a cooler on it.. (just keep in mind, the current X2 also can draw 4,2W on one core, and the better efficiency only visible on the same usage, so if you raise the clock speed from 3GHZ to 3,3Ghz or even 3,6Ghz, you can forget the better efficiency , you just gain better performance on nearly the same heat generation)
From tiny Acorns the mighty oak grows.
Did you ever release Speed Test G for purchase as an app?
No, I didn't because at the time I didn't want the smartphone makers to get hold of it and start "optimizing" their devices for it.
@GaryExplains: Just a thought, to get your views. Since ARM clearly focused on improving efficiency in this year's models, wouldn't it make sense for SOC manufacturers to have 2*X3s alongside 3*A715 and 3*510 ( maintaining similar frequencies to present flagship processors, maximizing the power efficency & sustained performance with less heat). I think a tensor like setup wouldn't achieve that much efficiency as compared to the setup above. I didnt see any similar set-up in ARM's slides, so was wondering if there is something that doesn't permit that kind of layout.
What you are suggesting is what Google did with the Tensor with the exception that you add an extra middle core rather than have four little core (so 2+3+3 rather than 2+2+4). Obviously that would be faster for multi-core scores, but not by a huge amount. The point is that since 12 cores are now supported then there are lots of possibilities. Arm was just showing a few key examples.
@@GaryExplains Precisely, as you explained. Thanks for the quick reply. I wonder if any of the manufacturers would take the leap of faith and increase the number of cores for the early 2023 SoC launches. With all the talk of the overheating and power hungry cores, i think this year would be a consolidation, especially since 3nm is in infancy at best and 4nm is just reaching to maturity efficiently. I think we are likely to see most of them stick to the currently more efficient 4nm process and 8 core setup, with next year's Plus lines or 2024 SOCs jump to a 10 core or 3nm process or maybe both together.
The 32 bit apps are massively used/developed in China. That may be the reason they are keeping it since Chinese market is one of the biggest out there.
Makes sense because google already has a policy to force devs to make apps and update to old apps to have a 64 bit version but china doesnt use play store
8+4+0... Cool, that means in the X4 generation we could see a potentially 8+4+2 or even 8+4+4?, That could close to and apple M2 CPU, maybe better?
#BringBackSpeedTestG
I like your enthusiasm!
Gary plz make video on cache memory explain it in depth.plz
You mean like this? ua-cam.com/video/roeZs-eL-lw/v-deo.html
You made "A", Prof!
How difficult will it be to go from 4nm precess to 1nm process?
And what could possibly come after 1nm process design and when should we expect it?
It's going to be really difficult. I don't know too much about it but currently, both TSMC and Samsung are having difficulties manufacturing in more advanced processes than 4nm due to low yield rates and high chances of chip failure.
As it stands, TSMC's schedule for 2nm process has been pushed as far back as 2026 and to make matters worse, 2026 is rumored to be the closest time to expect this process.
Will things get better as time moves on? We'll have to wait and see. But for now, we can only wish for the best.
Lower than 1nm we will be down to Angatroms. Without printing certain features individually with an electron beam, or some revolutionary new doping element, it can't really go below 2nm...
There's a thing called quantum tunnelling. If manufacturers aren't lying, mean if 3 nm is really 3 nm, not some marketing gimmick, then quantum tunnelling should start showing effect from there itself, making it impossible to go any further.
It is really up to ASML. They make the equipment that actually etches the chips. They are years away from making equipment that can write 1 nm.
Quantum computers?
When can we see SMT and Heterogeneous System Architecture (HSA) in ARM?
I have heard of any plans for SMT. My naive understanding is that SMT isn't a great trade for the added power and area.
up to 12 cores can be used for mid-small cores increase in smarphone chip as well, why they didn't mention something like 1+5+6 cores? there would be a pretty big room for performance increase by small frequency cores, not affect thermals too much I guess, but calculation power should be great
There are many combinations possible, Arm was just giving some examples.
Sup buddies 🙌
ARM and Nvidia have move so far ahead now but there's still zero rumours on new Nintendo Switch Pro/Gen 2.
Really want to see what an 8+0+4 setup can do for a maximum gaming performance and maximum efficiency when streaming video on youtube. As for Tegra, really hope that it will support DLSS 2.0 out of the box and we can see 1080p60fps on handheld mode and 1440p60fps on dock with both having internal resolution around 50% of its output resolution. We can then maybe see a simple GPU scaling work in tandem with DLSS, so that on dock mode, the 1440p output res. will fit perfectly on a modern 4k display, whether using a standard integer scaling, bilinear or whatever, that fit into a given game art style.
nice i think mediatek should make a true successor to Helio X30
Deca Core is very Impressive but in release of Dimensity 1000 they go back to 8Core im looking forward for new Dimensity With 10 Core CPU and 11GPU for more Performance but in 4nm
idk how does more cores help at 8core base
Somebody please build an SBC out of these X3 processors :)
4 + 8 would be great for a pixel laptop IMO
Prof. Will X3 come to A16 bionic?
Apple doesn't use any Arm designed CPU cores, it designs its own.
I wonder when they will start the 128 bit processors?
We will never need them.
We don't even use the upper bytes of a 64 bit pointer.
I have a video about 128bits here on this channel. It is already being used for vector and SIMD operations. But, we don't need it for memory addressing.
X3 will come with 8 gen 2?? Or later?
Yes, in the 8 Gen 2.

X3 is another beefy A715?
Or completely redesigned?
The X1 and the A78 were close in design, however with the X2 and now the X3 there is quite a lot of divergence. The X3 is quite different internally to the A715.
Minute 8:20 that chart is wonky. Please put 0 for the min of the Y axis. That’s would reflect the speed up more clearly. Nice overview. Thanks.
That chart is from ARM, Gary didn't make it
@@jordancave6987 ah. That explains it. Messing with the Y axis is the first trick to exaggerate differences.
how will the new arm cortex x3 enabled mobile processors stack up against the Apple A15 Bionic 🤔
From the leaks Qualcomm will adopt a 1+4+4 layout which ARM says will offer a 21% improvement. The 8+ Gen 1 scores around 4200. So around 5100. Which is around 10% faster than the A15. If not higher since Mediatek with the current architecture scores around 4400.
@@alexseleni3314 hmm. also apple and the A15 use ARM right? so they will be using this new cortex too i assume
@@Syed-wj4pj no they won't since Apple still has more powerful cores. They only need to use 2 power cores in their phone, instead of 4 power cores like Qualcomm.. If you even increase the rumored 1300 Single core performance in Qualcomm SD8+ Gen 1 with the 20% performance boost that is still only 1500-1550, so they can reach that in the future, but Apple already reached 1700+ Single core performance in A15 chip. Why do you think the 1550 is a step forward, after they already had 1700 one year ago..?
@@Syed-wj4pj Well switching back to ARM takes a lot of time even though it seems simple. Apple will probably never abandon their custom silicon even if it falls behind.
If their geekbench numbers are true then the 12 core part is gonna have a score of about 9200(on a TSMC node). Which is even stronger than the M2.
Why has it taken them this long to catch up though ffs - it's been difficult buying Android phones for a while because I know they are mostly hot laggy messes.
@@HouseOfFunQM I mean the Dimensity 9000 is only 10% slower than the A15. Also if you actually use flagship Android phones you'll rarely experience lag. Especially from OnePlus or Google phones.
Then why not compare the 12 core to the 12 core M1-Version?
@@manulovesjesus Cause it's a different layout. This is probably gonna cost as much as the M2. ARM uses more but "less" powerful cores to achieve the same performance. When AMD released Ryzen did we compare to Zeons?
@@HouseOfFunQM you are so wrong those were the old days where they don't have good hardware and no software optimization mostly before android 4.0 nowadays, the are comparable to Apple's chip in terms of hardware, still lags behind in software optimization but not so much.
So the conclusion is they are not hot laggy mess. They are fast and cool like Apple's chip.
or maybe a holo iso video , steam os on other hardware
no timestamp?
Why not 6x3 cores 6x2 configurations
30% improvement yoy is extremely impressive.
So how long before chip makers adopt these.
I thought I covered that in the video. You can expect to see these in flagship phones in early 2023.
HE's still wearing Android Authority t-shirt without any hesitation.🙂
when to see AAA games run on the awesome arm CPUs?! when to see something to compete with apple arm?!
Will 3nm GAA improve performance drastically Than finfet?
it will be a bit better TSMC's 4nm but TSMC's 3nm will be quite a bit better.
@@eruptic6503 But tsmc 3nm is still finfet so I would have expected the gaafet might still be better no?
@@sbrader97 There is more to a processing node than just the transistor technology
@@ashar8192 I know that i just thought that its now getting to the limits of what finfet can do but I hope that samsung 3nm is at least competitive and not miles behind like samsung finfet nodes have been
@@sbrader97 in terms of transistor density Samsung has catched up to TSMC (4LPE vs 5P), but the yields are horrid, so the v/f curve is much less efficient.
Gaa's on 3GAE will improve efficiency, but it's potential will be held back again, by bad yields
The real question is, how much slower is compared to the latest apple silicon?
assuming TSMC is the main foundry, not too distant
WELL THEY HAD TO BE FASTER FOR THE ROBOT ARMY . aye aye aye i forgot moi caps lock . well shit . my appologies eh getics , yeah apollegetics .
Starting with M1 series from APPLE other consumer CPU chips just kind of lame. Really looking forward to see some competition but seriously at the moment and probably in the next 1 or 2 years I doubt it will change much.
I would like to be surprised though.
The M1 uses the same CPU as the iPhone. So it is about Apple's iPhone CPU core designs, not the M1. Apple's CPUs have been ahead for many years. The Nuvia based CPU from Qualcomm has the potential to shake things up a bit. I have a video about it here on this channel.
its not possible apple uses very expensive fabrication and expensive level2 cache unlike others.
so its aomost impossible to match performance of apple cpu.
and also apple chips aren't as versetile
@@anandsuralkar2947 They also have full stack integration as well ie Apple Silicon + MacOS + Apps. Nuvia will "close the gap" but not cross it as it's a moving target, by then Apple M3 etc.
Why they focus on “peak performance“. They should focus more on “sustained performance”. thermal throttling is a thing 🤦♂️
Its an SoC designer job not arm
Because hard to sell the same thing, if "only" has a better efficiency, but peoples don't see any differences in numbers, what showed in the benchmarks. Most of the world is not a tech guy, they need to see the differences in numbers, and sadly the efficiency is only visible in the battery time, but that can be solved just with a bigger battery (and regular people just happy about that, because it's have a bigger battery..)
Better perf can be used in 2 ways.
1 higher perf at the same power.
2 the same perf at lower power.
So arm did what you wwnt, but it's not how they will market it.
Nor likely how the system integrators will integrated it.
As everyone is doing what the market demands.
is the cortex x3 a mobile processor?
It is a CPU designed to go in mobile processors, i.e in SoCs like Snapdragon, Exynos, and Dimensity.
It's a core
Can be used in mobile processor
Qualcomm bought that company of ex Apple cpu designers, just to use the ARM designs?
No, not Arm's designs, Apple's designs. I have several videos about it here on this channel.
Next stop
Removing 2G/3G from modem so the SOC have more space
remove 3g but not 2g
@@hellotheir1427
2G is also useless now.
All country already have very good 4G/5G network.
maybe a FPGA over cloud video, or maybe pretend you have to use only arm based software for your fortune 500 company video?
If licensees create designs in a clean room, why does it matter what ARM creates?
I don't quite understand. Most of Arm's clients use CPU cores designed by Arm, only a rare few do their own designs (i.e. Apple).
Still second rate.
Disappointed... Apple's gonna have a bigger lead now ==
Catching apple design is very difficult task. I still wonder how the hell they can make their cores way faster than any arm design. I don't think arm doing bad but apple definietly did it better
@@Arkan_Fadhila Nah, ARM is doing bad. Their current A710 and A510 cores are actually worse in performance per watt than the last generation.
@@Lvlaple4Ever even if intel and amd are fully switch to arm and take several years to close the gap to apple design, i think they never able to surpass apple design. I think It's apple doing way too good compared to the competition. I wonder if close ecosystem make them able to optimize their design better or not.
@@Arkan_Fadhila I think they have a lead because of they are don't need to make any compromise with any other companies. If you can do everything inside your company, that gives you more possibility (and even if you make compromises with others, you will never allow any outsiders from other company inside your office safe, they are just able to see around in your office, the safe is closed for them, so there are no full access for the outsiders compared to the insiders, what just make things a bit more difficult to work together, and this is why the can't reach the same efficiency and harmony)
@@randomcomment9992 realize, it was always qualcomm/arm/tsmc since the first iphone. Qualcomm and ARM stagnated.
Thank goodness, mediatek, google, nvidia and samsung have jumped in. Qualcomm is pressured to compete better with mediatek, samsung wants to go in house and ARM now is pressured by mediatek to make better cpu's.
why does X2 sucks ?its worse than 845(x1) i guess
The X1 was in the 888 not the 845. Why do you say the X2 was bad? What data are you using to prove that?
