Brand new entry of Intel's flagship ARC Alchemist graphics card based on the Xe-HPG architecture has been leaked within the SiSoftware Sandra database. The new entry is for the 32 Xe SKU (DG2-512) which features 4096 ALUs and a clock speed of up to 2.10 GHz. There's also 4 MB of L2 cache and the GPU most likely features 16 GB of GDDR6 memory configured along a 256-bit wide bus interface. It's easy to tell that this is still an engineering sample considering that it has no official branding attached to it whereas the ARC A380 has already shown up in SANDRA with its naming scheme.
The top Alchemist 512 EU (32 Xe Cores) 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.
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.
