Intel’s Arc Alchemist mobile GPU specs detailed in leaked slide

0

We’ve talked a lot about Intel’s upcoming Arc Alchemist series of discrete graphics cards, and now we also have some seemingly concrete details about Arc GPUs for laptops. The leak comes from @9550pro, a well-known leaker (via Techspot). The build shows what looks like a legitimate Intel slide that lists five SKUs.

The leaked slide is titled “Configuring DG2 Graphics Memory”. It lists the main specs of five laptop SKUs.

The high-end SKU (SKU1) seems to have very similar specs to the desktop Arc board with 512 execution units, 16 GB of 16 Gbps VRAM (surely GDDR6) which provides 512 GB/s of total bandwidth on a 256-bit bus. The clocks aren’t revealed, but with this spec it’s likely to be a clocked, lower variant of the desktop card. If it ends up performing around the RTX 3070 or 3070 Ti desktop levels, it could be a powerful gaming option.

The second card is touted as having 384 EUs, 12GB of 16Gbps VRAM, and 384GB/s total bandwidth on a 192-bit bus.

Next is the mid-range SKU3 which seems to be basically half the top SKU, with 256 EUs, 8 GB of VRAM and 256 GB/s of bandwidth on a 128-bit bus.

The low-end versions contain 128 and 96 EU respectively. It’s likely that they’re both the same GPU, with the smaller model using a harvested die. They feature a base VRAM of 4 GB at 14 Gbps on a 64-bit bus for a total of 112 GB/s of bandwidth. The 96 EU is curious because Intel produced Tiger Lake mobile processors with 96 EU integrated graphics.

It remains to be seen how these GPUs perform in games. One company that will be paying close attention will be Nvidia, which has a long-standing stranglehold on the laptop GPU market. We can’t imagine Arc Alchemist GPUs will rival Nvidia’s high-end offerings, but laptops with 3050 and 3060-class gaming cards are sure to see some competition in the market, depending on how aggressively they are. ‘Intel and Nvidia, or more specifically, how big the checks are.

We don’t have information on clock rates and TDPs, but the pieces are coming together. We can’t wait to see how Intel’s Arc GPUs perform. Much will depend on the quality of the pilot. The best GPU in the world will not receive a positive reception if the driver sucks. No doubt we’ll be all over Intel’s mobile and desktop Arc GPUs before and after release.
