Intel"s highly anticipated Arc GPUs are rumored to launch in the first half of the year itself - as early as March - and that means a few leaks here and there are bound to be expected. As such, reputed leakster on Twitter, HXL, posted an image on their handle which apparently shows the 1st Gen Arc Alchemist SKU lineup for notebook GPUs.
We have had known the Execution Units (EU) count for Arc GPUs for a while now; however, the memory sub-system was still mostly based on guesswork. The only thing confirmed were the capacities of the top-end and lowermost SKUs at 16GB and 4GB respectively. However, the new leaked image sheds more light on the purported memory configuration like memory interface width and maximum bandwidth.

Interestingly, there appears to be no 6GB VRAM part, at least for the mobile lineup as both SKU4 and SKU5 will seemingly feature 4GB of memory. Another thing missing is 18Gbps GDDR6 VRAM which was supposed to be on the flagship SKU1 part instead of the 16Gbps we have here. However, the faster 18Gbps memory could still be a part of the desktop Alchemist (DG2) lineup.
There is also no sign of the rumored 448 EU Alchemist GPU that leaked towards the end of last year. However, this one too may be part of the desktop lineup only.
