Intel Arc Alchemist SKU2 (384EU) pictured, features Samsung G6 memory

Twitter user kuna published a photo featuring Intel’s upcoming discrete Arc Alchemist graphics card. 

The following picture shows the DG2-512 graphics processor from Intel. This is the upcoming 6nm GPU based on Xe-HPG architecture and part of the Arc Alchemist product family. It features 6 memory modules labeled as Samsung K4ZAF325BM-HC16. This means that each of those chips offers 2GB in capacity and 16 Gbps bandwidth.

As it turns out, the memory spec table that leaked this week actually had the same origin (Chinese Tieba Baidu forums). It was, in fact, shared more than 7 months ago, yet, it only surfaces this month. Regardless of this fact, we can now quickly identify which Arc Alchemist card has been photographed above, while of course, not being sure if this is a desktop or mobile GPU.

With 6 memory modules around the processor, this should be the 384 EU variant, so a cut-down model known as SKU2. It is to feature 12GB GDDR6 memory across a 192-bit memory bus with a bandwidth of up to 384 GB/s.

It may not be easy to read the label from the first photograph, which is why we made this enhanced version showing most of the letters.

Interestingly, exactly this memory model is now being listed by Samsung as ‘Sampling’. This is despite being listed as being in ‘Mass Production’ just a month ago.

We are not sure why Samsung has changed the status of this memory type or why has 18/20/24 Gbps memory has been delisted from the product catalog. In any case, Arc Alchemist GPUs are now set to launch this quarter. There is currently no information whether the ‘Q1 2022’ promise refers to both desktop and mobile GPUs or even if this includes both GPUs (128EU & 512EU).
