Brand new details regarding the Intel ARC Alchemist lineup of gaming graphics cards have been leaked by Moore's Law is Dead. The new leaks cover the performance and positioning of various GPU configurations within the ARC lineup that is launching in Q1 2022.

Intel ARC Alchemist Gaming Graphics Card Rumors: Three Xe-HPG GPU Configurations Aiming High-End & Entry-Level Segments

According to the rumor, Intel will have at least three configurations of ARC Alchemist GPUs ready for launch in Q1 2022. These will include two configurations based on the top 512 EU die and one configuration based on the 128 EU die. Although there are more GPU configs that we have seen in leaks, it looks like those may be used in future products though that cannot be confirmed. So let's start with the top-end configuration.

MLID has leaked the latest information regarding Intel's ARC Alchemist gaming graphics cards & respective GPU configs.

Intel Xe-HPG 512 EU ARC Alchemist Graphics Card

The top Alchemist 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 featuring a 16 Gbps clock though 18 Gbps cannot be ruled out as per the rumor.

The Alchemist 512 EU chip is expected to measure at around 396mm2 which makes it bigger than the AMD RDNA 2 and NVIDIA Ampere offerings. The Alchemist -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 flagship Alchemist 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 will also have dedicated hardware onboard its Alchemist GPUs for Raytracing & AI-assisted super-sampling tech.

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 a speculative measure of performance, MLID states that the TFLOPs make no sense for comparison as performance scales differently respective to the architecture, not the FLOPs performance. The gaming graphics card is pretty much expected to be faster than the RX 6700 XT & RTX 3070 at this point but with work ongoing on the driver suite, the performance is expected to improve further.

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. That reference design was leaked a while back by MLID too. There're also talks about a custom lineup being worked upon by Intel's AIB partners.
