Intel's planning to become a major player within the GPU market, and that effort is taking the company on a two-pronged approach with their Xe graphics architecture. Intel needs high-end accelerators for HPC workloads and high-end gaming-grade and workstation-grade graphics products for consumers, and all of those workloads require market-specific optimisations.  

With Arctic Sound, Intel's ambitions were high, a tile-based GPU design that can deliver scalable performance across multiple GPU/accelerator chips to deliver tremendous performance numbers. Thanks to Igor's Lab, we have gotten a look at the company's 1T and 2T HPC accelerator cards. 

Intel's 1T and 2T naming scheme isn't difficult to decipher, standing for 1-Tile and 2-Tile, respectively. Strangely, Intel's long-teased 4-Tile Arctic Sound variant is a no-show, suggesting that Intel's Arctic Sound Accelerators have been facing production issues. 

Arctic Sound reportedly relies on high-speed HBM2E memory, with each tile featuring 16GB of the high-speed memory type. This gives each accelerator tile access to 716 GB/s of bandwidth. 

Intel's 1T setup reportedly features a TDP of 150W, offering users 384 usable Execution Units (EUs) out of a total of 512. Igor's Lab suggests that Intel is running into yield issues with their Arctic Sound silicon, resulting in non-peak EU counts and lower clock speed/power targets. 

With 8 shader units per Execution Unit, Intel's 1T arctic Sound Accelerator will feature 3072 shaders. Intel's Arctic Sound Accelerators reportedly use a PCIe 4.0 interface and feature no display outputs.

Intel's 2T Arctic Sounds Accelerators are a lot more impressive than their 1T model, offering two tiles with 480 Execution Units each. This gives the accelerator a total of 32GB of HBM2E memory and a total of 7680 (2x3840) shaders. This is still below Arctic Sound's theoretical Peak of 512 EUs (4096 shaders) per tile but a lot closer to peak die utilisation. 

With a TDP of 300W, Intel's 2T Arctic Sound Accelerator requires an 8-pin EPS connector for power, a connector type that is commonly used for CPUs in the consumer market.

These leaks suggest that Intel has toned down their ambitions for Arctic Sound but highlights that the company has a functioning multi-tile graphics card working in-house.

Their naming is just so ludicrous and dull. Arctic sound.. in the PC world you would associate it with a sound card. Whoever is responsible for naming all their products, really needs to stay off the medication.Quote

Yeah, I thought that this was about a sound card and I thought to myself "who the hell uses sound cards these days and why is Intel making one?"Quote

i realized it was a video card when i read 7680 xe cores...but i think the 99,9% ppl will think this like a sound cardQuote

The Intel sound cards are called: Mountain vision :PQuote
