As an open source Open GL / Vulkan driver, we found some clues in the Mesa code submitted recently, indicating that Intel is brewing a 448 EU DG2 SKU.In addition, Francisco Jerez, a member of the Intel open source driver team, basically confirmed the existence of the 448 EU version reduced from the DG2-512 GPU.As for whether it will appear as a commercial product, it is currently unknown.
As early as five months ago, @TUM_APISAK had already exposed a simplified version of the DG2-512 GPU on Twitter, and expected its performance to be comparable to Nvidia’s GeForce RTX 3070, although the exact benchmark comparison was not disclosed at the time.
In terms of core size, it was revealed that the DG2-512 GPU is about 396 m㎡, which is moreAMDThe RNDA 2 and Nvidia Ampere competitors are slightly larger.
In terms of performance, asIntelThe flagship GPU here, Xe-HPG architecture is expected to compete with RTX 3080 and Radeon RX 6800 XT.
If all goes well, Intel will release new ARC Alchemist graphics cards in the first quarter of 2022. However, as of now, we have only heard of two versions of 128/512 EU.
The legendary 384 EU derivative version has not yet been fully disclosed to the public.
WCCFTechIt is pointed out that the DG2-512 GPU will be packaged in BGA-2660 with a size of 37.5mm x 43mm. The NVIDIA Ampere GA104 has an area of 392 m² (equivalent to DG2), and the Navi 22 GPU has an area of 336 m² (about 60 m² smaller).
The difference is that NVIDIA has introduced TensorCore and larger RT/FP32 components in its own chips, while AMD RNDA 2 is equipped with a light tracking unit for each group of CU/Infinity Cache.
If Intel does not release the DG2-384 EU in the first half of 2022, then the company is likely to use the 448 EU derivative version (3584 Shading Cores), which is reduced from DG2-512 EU, as the main force in the mid-market (estimated priced at US$300-400).
