Most people already know that you shouldn’t use an Arc GPU without ReBAR. However, since the launch of the B580, there have been many new users, so for those who weren’t aware-now you know.
Can do the same test on 1080p? Same relative drop or lower? Or on usb4 Egpu solution which usually does not have rebar implementation (if I am not wrong) to see the impact ?
This card has been aimed at budget buyers, who are far more likely to be on older hardware to begin with. I've seen people on reddit recommend this card to such users. I guess we should blame the tech review sites for overhyping it. If it wasn't for the price, there would be no reason for anyone to get this card. And outside the US the price isn't even low anyway.
@@FullNietzsche I think most mainboards for Intel 8th gen and above support rebar with a bios update, which is old enough, not sure on AMD 's end. Anything older will probably bottlenecked this GPU badly anyway.
I have the impression that in the case of battlemage there is an even bigger difference after disabling rebar than in alchemist, which unfortunately means even greater addiction
Indeed! haha I updated my MB bios and forgot to turn on Rebar again. I learned very quickly about that :) Loaded up my game and was skipping every where XD
It's always the same when a card like this one comes out. Just give it time for the fever die down and the shops will eventually re-stock nearly at the suggested price.
CPU usage has almost doubled from Alchemist. That's 50% now if not more taking the lows in count. This with AMD CPU. Comparison to 265K with supported CUDIMM 8400 would be interesting. Then we see what the E Cores do.
It's in the BIOS. You need to shut off CSM (so if you plan on running ReBAR, you may need to reinstall Windows under a GUID partition, otherwise you won't be able to boot). Also some "above 4G decoding" has to be on. If you're on AM4, basically the only hard requirement for ReBAR support is a third gen Ryzen CPU or later. I'm using a "launch day" AM4 board and with a BIOS update it was there, though I did have to upgrade the ageing CPU. I don't know what the situation is on Intel, they've changed sockets and chipsets probably five times since I bought my (still supported) AM4 board.
You don’t need to reinstall windows necessarily if your are running a MBR install. You can use command prompt and windows recovery to convert MBR to GPT and should work fine without CSM
@@IntelArcTestingMost definitely correct, kind of forgot about that. I had to wipe the partition and reinstall cause Windows update decided to irreparably kill the Windows install. I couldn't even use recovery or an OS upgrade. Only reason I'm still on that rubbish is the weak Linux driver support and my total inability to install ARC drivers at all.
@@s4yto Iam good, Because i have researched this before hand. I'll just have to make sure my Bios is updated and once i plop in the 5700x3d it should let me enable resizeable bar with a supported GPU.
Eso de Rebar es una simple estafa al consumidor, por que no simplemente hacerlo por software? Microsoft es la ruina,me pregunto si en linux es el mismo cantar o solo es por hardware en la placa base.

You're doing all the testing that all the big tech channels should have done.

Yeah probably because it uses x8 instead of x16 and smaller bus width

I was curious about this. Looks like rebar makes even more of a difference than alchemist. Thanks for testing.
It's a shame that Intel Arc B580 is out of stock everywhere.
Not in EU but pricing is not great
@@IntelArcTesting not buying at that terrible price

€319 for the Steel Legend. I got it for €309. Its not that bad, actually. Not in all of Europe. @@IntelArcTesting
do you have a 10600k or within that series of CPU to do testing with?

Can we get a test with adaptive tesselation on? Off vs 50 vs 75.
More A750 please
Can you please try space marin2 2? Apparently performance is pretty mixed.
Bro what is rebar ?
How do you know if your motherboard has the rebar on?
It's in the BIOS. You need to shut off CSM (so if you plan on running ReBAR, you may need to reinstall Windows under a GUID partition, otherwise you won't be able to boot).

iNTEL still hasn't includeD HW for small memory transfers. 🤣NV and AMD have memory controler optimised FOR SMALL mem transfers SINCE FOREVER 🤩
So the ARC has no stand alone CPU cores
In this case this is the dedicated GPU you slot into your system. They do have an integrated GPU still for Arc on their processors.
@PixelatedWolf2077 coming soon , ARC laptops I would smash on one
@PixelatedWolf2077 GPUs have interpretation cores like CPU cores in the architecture
Noted upgrade my CPU first

@@s4yto huh? I got an AM4 B450 board ... so all i need is a CPU that supports this feature set and the 5700x3d does
@@HackoDis yeah its both cpu and motherboard that needs to support the feature, some old am4 motherboards don’t support it
