Intel’s graphics card ambitions may be greater than we initially thought. Digital Trends has gotten its hands on a platform chart that reveals a complete lineup of Xe GPUs, which range from low-powered variants to high-performance SKUs boasting TDPs of up to 500 watts. Not even AMD’s hungry Radeon VII (300 watts) comes close to that.
There appears to be three GPUs slated for release in the consumer or enterprise markets. All of these cards utilize “tiles,” which alludes to a multi-die, chiplet-based design. Intel hasn’t specified how many execution units each tile carries, but 128 is a plausible number based on a driver leak from last year that listed EU counts of 128, 256, and 512.
These numbers line up with the number of tiles attributed to each card in the platform chart. The weakest card will have one tile (128 EUs) and a 75 or 150 watt TDP, while the mid-range part carries two tiles (256 EUs) and a 300 watt TDP. Sitting at the top are the power hungry 400 or 500 watt cards, which have four tiles (512 EUs)
We’ve already seen the single-tile card in the form of Intel’s DG1-SDV software development vehicle. The others are still a mystery, but there’s a good chance that they’re workstation cards due to the high TDPs and 48 V input voltage, which is typically reserved for server environments.
The documents also confirm that Xe will use HBM2e memory. PCIe 4.0 will also be supported.
