As per the latest, leaked information offered by Moore’s Law is Dead, we could have some new information on our hands regarding Intel’s ARC Alchemist lineup of gaming graphics cards. The new leaks cover the performance and positioning of various GPU configurations within the ARC lineup that is launching in Q1 2022.
According to sources, Intel is poised to offer at least three configurations of ARC Alchemist GPUs ready for launch in Q1 2022. this configuration includes two 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, this information is pretty juicy.
Intel Xe-HPG 512 EU ARC Alchemist Graphics Card will be the top Alchemist 512 EU variant which has only one configuration listed so far and it will utilize the full die with 4096 cores, 256-bit bus interface, and up to 16 GB GDDR6 memory while featuring a 16 Gbps clock.
The Alchemist 512 EU chip is expected to be bigger than the AMD RDNA 2 and NVIDIA Ampere offerings and will come in the BGA-2660 package which measures 37.5mm x 43mm. The Xe-HPG Alchemist 512 EU chip will feature clocks of around 2.2 – 2.5 GHz and is expected to deliver up to 18.5 TFLOPs FP32 compute.
MLID also stated that the gaming graphics card from Intel could pretty much be faster than the RX 6700 XT & RTX 3070 and the performance is still expected to improve further.

Intel Xe-HPG 384 EU ARC Alchemist Graphics Card
Moving on, we have the Intel Xe-HPG Alchemist 384 GPU which and will be a cut-down variant of the 512 EU die. The 384 EU chip features 3072 cores and boasts up to 12 GB GDDR6 memory, including a 192-bit bus interface. The card would also feature a TDP of around 200W and will come with a 16 MB smart cache.
Intel Xe-HPG 128 EU ARC Alchemist Graphics Card
finally, it’s the Intel Xe-HPG Alchemist 128 EU and comes with 1024 cores, a 64-bit bus interface, along up to 8 GB of GDDR6 memory. We also have a cut-down variant which will come with 96 EUs or 768 cores and a 4 GB GDDR6 memory as well as a 64-bit bus interface.

| Xe-HPG 96EU | Alchemist-128EU | 86 EUs | 768 | 4 GB GDDR6 | 64-bit |
The Xe-HPG Alchemist lineup will be competing against NVIDIA’s Ampere & AMD RDNA 2 GPUs since both companies aren’t expected to launch their next-gen parts by the very end of 2022. Next year the GPU market will be on fire, as we will have three high-profile competitors combating for the market share.
