An alleged Intel ARC Alchemist graphics card based on the Xe-HPG DG2 GPU has appeared within the Ashes of The Singularity benchmark.
Intel's ARC Alchemist DG2 Gaming Graphics Card Pops Up In Ashes of The Singularity Benchmark
We can tell that this is indeed a discrete graphics card based on the performance it offers and the fact that it was featured on a system running the Intel Core i9-12900K Alder Lake CPU. It looks like that this could be one of the early samples that is being tested before the full demo and unveil at CES 2022.
The Intel ARC Alchemist graphics card was tested at the Medium 1080 preset and scored 12500 points with an average of 126.9 FPS. The AOTS benchmark database isn't the most reliable of all when it comes to comparing scores due to different versions and custom presets being used. As such, we don't want to go ahead and compare performance since the score puts it on par with an RTX 3080 Ti but the RX 6700 XT and RX 5700 XT also offer the same score. So you can see why I've advised from comparing the results.
Intel Xe-HPG 512 EU GPUs Powered ARC Alchemist Gaming Graphics Lineup
The top Alchemist 512 EU (32 Xe Cores) variant is said to feature at least three configurations. The full die features 4096 cores, a 256-bit bus interface, and up to 16 GB GDDR6 memory featuring a 16 Gbps clock though 18 Gbps cannot be ruled out as per the rumor. Following are all the ARC 512 EU variants that we can expect based on the DG2-SOC1:
- 512 EU (4096 ALUs) / 16 GB @ Up To 18 Gbps / 256-bit / 225W (Desktops) & 120-150W (Laptops)
- 384 EU (3072 ALUs) / 12 GB @ Up To 16 Gbps / 192-bit / 150-200W (Desktops) & 80-120W (Laptops)
- 256 EU (2048 ALUs) / 8 GB @ Up To 16 Gbps / 128-bit / 60-80W (Laptops)
The Xe-HPG Alchemist 512 EU chip is suggested to feature clocks of around 2.2 - 2.5 GHz though we don't know if these are the average clocks or the maximum boost clocks. Let's assume that it's the max clock speed and in that case, the card would deliver up to 18.5 TFLOPs FP32 compute which is 40% more than the RX 6700 XT but 9% lower than the NVIDIA RTX 3070.
In terms of performance positioning, the top 512 EU variant is said to compete against the RTX 3070 / RTX 3070 Ti, the 384 EU variant is said to compete against the RTX 3060 / RTX 3060 Ti on desktops. On the laptop side, the 512 EU might be just as fast as the RTX 3080, 384 EU variant around RTX 3070 level and the 256 EU will end up against the RTX 3060.

|Memory Capacity||16 GB GDDR6||8 GB GDDR6X||12 GB GDDR6|
|Launch||Q3 2022||Q2 2021||Q1 2021|
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. In either case, we can expect the final model to rock an 8+6 pin connector config, The reference model is also going to look very much like the drone marketing shot Intel put out during the ARC branding reveal.
As for the launch, the SOC1 variants are planned for launch in Mid-February & while AIBs are waiting on final dies to test with their custom PCB designs, desktop variants may be launching first, followed by laptop and then workstation in late 2022.
