Intel DG2 Xe-HPG Features 512 Execution Units, 8 GB GDDR6

in this case the real question is can it run Crysis? or only tetris...

Oh yes please, give us stronger iGPU so AMD would make RDNA based APU

This is just the beginning. I can't wait for a full Intel build with CPU + GPU + Optane SSD.

I was right to be cautious, the official documentation of Intel about GPU rendering on Blender only talks about OpenCL, it doesn't seem like their driver are going to run Optix/CUDA apps like it was native:
GPGPU: Blender (intel.com)
ZLUDA is a project that can make it possible, but Intel isn't involved:
ZLUDA: Drop-In Open-Source CUDA Support For Intel Xe / UHD Graphics - Phoronix

So it looks like it will once again be in the hands of the developers to use OneAPI instead of CUDA, and sucess where Open Cl failed. (Wich could be a good thing since OneAPI isn't exclusive to Intel.) The good news is that the CPU side of OneAPI is already used by a few popular render engines, so maybe there's hope.

Don't forget about this. Intel could make very high end GPUs, I think they won't until they have more 10nm / 7nm capacity.

Tiger Lake's Xe IGP wasn't a disaster, and that was 25W comparable to Vega8.

If we take a Vega8 and multiply by 5.3 to emulate the shift from 96 to 512 EU, we get a "Vega42". That's not exactly bleeding edge, given that a Vega64 is starting to show its age, but 2/3rds of a Vega64 would probably put it in the ballpark of a GTX 1060 6GB or RX570.

Vega8 needs much higher GPU clocks to stay competitive against Xe LP. Even at 2100 Mhz it can lose in some against 1300 Mhz Xe LP. Also Xe LP is more bandwidth starved than Vega 8, the difference from DDR4 to LPDDR4 is quite big on Xe LP unlike on Vega8. The real gamer Xe will run on GDDR6 and won't be limited to DDR4/LPDDR4 and also it should clock a lot higher in a more power optimized environment, Xe LP is low clocked these days in comparison.

This is true. It's somewhat amazing that this gets said but Intel is stepping up to the plate in the GPU game, and doing well. Kind of refreshing actually.

Vega 8 is 8CU - 512:32:16 (SP:TMU:ROP).
Big Xe is 96EU - 768:48:24.
Intel is using a 50% bigger iGPU configuration.

The point is a simple multiplication to emulate the shift from 96 to 512 EU won't work unless he assumes a big dedicated GPU from Intel will stay on such a low GPU clock speed at 1300-1350 Mhz. It's a bit different if DG2 clocks at 2000 Mhz for example. Vega has been clock speed optimized for several generations, there is no real headroom anymore.

That's not true. But it's also not relevant anymore. AMD is moving away from Vega on it's iGPU packages. It is those advancements that Intel has to compete with.

Why it isn't true? AMD uses Vega since Raven Ridge. Cezanne barely started, why it isn't relevant? Cezanne has to deal with ADL-P this year for some time.

Raven Ridge - max 1300 Mhz
Picasso - max 1400 Mhz
Renoir- max 1750 Mhz
Cezanne - max 2100 Mhz
