Die size of Intel's DG2-512 GPU based on the Xe-HPG graphics architecture has been measured by Twitter fellow, Locuza. The die shot was posted by Intel's Chief Architect of graphics, Raja Koduri, in a tweet, yesterday.

Intel DG2-512 GPU Die Size Measured, Xe-HPG Architecture Based Chip Is Bigger Than AMD RDNA 2 & NVIDIA Ampere GPUs

According to Locuza, the Intel DG2-512 GPU should measure about 396mm2 which makes it bigger than the AMD RDNA 2 and NVIDIA Ampere offerings. The Xe-HPG architecture-based chip might be the flagship but in terms of performance, it should be competing against the RTX 3080 and Radeon RX 6800 XT. It's definitely not as big as the flagship GPU offerings from either company but if we are to compare the high-end GPU category (Navi 22 / GA104), the DG2-512 is slightly bigger.

DG2-512 die is about 396mm² large.

DG2-512: 4096 FP32 Units, 256-Bit GDDR6

Navi21: 5120 FP32 Units, 256-Bit GDDR6 + 128MiB L3$

Navi22: 2560 FP32 Units, 192-Bit GDDR6 + 96MiB L3$

GA104: 6144 FP32 Units, 256-Bit GDDR6

The DG2-512 GPU will come in the BGA-2660 package which measures 37.5mm x 43mm. NVIDIA's Ampere GA104 measures 392mm2 which means that the DG2 chip is comparable in size while the Navi 22 GPU measures 336mm2 or around 60mm2 less. This isn't the final die size of the chip but it should be very close. NVIDIA packs in tensor cores and much bigger RT/FP32 cores in its chips while AMD RDNA 2 chips pack a single ray accelerator unit per CU and Infinity Cache. Intel is expected to have hardware-accelerated ray-tracing capabilities onboard it's Xe-HPG GPUs & a recent tweet from Raja also seems to point out hardware DL/ML capabilities that would assist in supersampling tech.

Intel Xe-HPG DG2 512 EU Discrete Gaming Graphics Cards Specifications

Each Xe-HPG based DG2 GPU SKU will come in various configurations which will range from the full-fat chip to several cut-down variants. This is similar to NVIDIA's Ampere GA102-400, GA102-200 naming schemes, or AMD's Navi 21 XTX, Navi 21 XT, Navi 21 XL naming conventions. The top DG2 512 EU variant has just one configuration listed so far and that utilizes the full die with 4096 cores, 256-bit bus interface, and up to 16 GB GDDR6 memory (8 GB GDDR6 listed too). Based on demand and yields, Intel could produce more variants of this flagship chip but we can't say for sure right now.

The Xe-HPG DG2 512 EU chip is suggested to feature clocks of up to 2.2 GHz though we don't know if these are the average clocks or the maximum boost clocks. Also, it is stated that Intel's initial TDP target was 225-250W but that's been upped to around 275W now. We can expect a 300W variant with dual 8-pin connectors too if Intel wants to push its clocks even further. We have also already seen leaked PCB and pictures of an ES Xe-HPG DG2 based graphics card which you can see here.
