Five Arc Alchemist GPUs for laptops are shown in a leaked Intel slide.

Intel's Arc Alchemist laptop graphics card portfolio that will be available in the near future has leaked. @9550pro has posted a slide from a (allegedly) internal Intel presentation online. The several models are listed in the following section.



Intel appears to be working on five different DG2 CPU types that are optimized for laptops. In addition to 512 execution units (eus) and 16 GB of vram, the top model will be implemented utilizing gddr6 at a 16 Gbit/s rate, which will allow for faster performance. When employing the stated 256-bit memory bus, this would result in a maximum bandwidth of 512 GB per second being achieved. 

Additionally a downsized DG2-512EU GPU with 384 EUs internally dubbed SKU2 is spotted. This edition will ship with 12GB of GDDR6 RAM spread across a 192-bit memory bus. It would maintain the same speed as the flagship portion, which supports up to 384 GB/s of bandwidth. The Intel ARC Mobile "SKU3" variant is built on the 256EU architecture and features 8GB of GDDR6 memory and a 128-bit memory bus. It would also include 16 Gbps RAM, but only half of the modules offered by the flagship portion. This means that the bandwidth will be halved to 256 GB/s.

SKU4 and SKU5 are based on a DG2-128EU GPU with 4GB GDDR6 RAM and a 64-bit bus width. The memory bandwidth would be limited to 14 Gbps, implying a maximum of 112 GB/s.

In general, this leaked presentation confirms the existence of all downsized DG2-512EU variants, which may also find their way to the desktop. Indeed, it would be quite remarkable if they did not. There is no trace of the anticipated 448 EU variation, which means that the flagship mobile ARC GPU and the 384EU model will have a core count difference of 1/3. The 448EU model, on the other hand, is expected to find its way to the desktop series.
