Intel shows large Xe HP GPU with four tiles

Intel’s chief architect Raja Koduri briefly showed his variant of the Xe HP GPU with four tiles during the virtually held Hot Chips 2020 conference. The company also unveiled a die image of a Tiger Lake quad-core processor.

Koduri briefly showed the 4-tile version of the Xe HP GPU during his keynote at Hot Chips 2020, after briefly showing the smaller 1-tile version at Intel’s Architecture Day last week. During the keynote he gave no further details about the chip.

The Xe HP GPU is Intel’s graphics chip for workstations and data centers, which will deliver it in variants with one, two and four tiles. These tiles are chips that Intel connects via its embedded multi-die interconnect bridge, or emib. Last week, Intel demonstrated its scalability. The four-tile variant would offer an FP32 processing power of 42 tflops, but thanks to the presence of tensor scores for calculations around artificial intelligence, Intel claims that the chip can offer petaflops performance, according to Tom’s Hardware. For high performance computing, Intel is working on Xe HPC, or Ponte Vecchio, while for gaming the externally produced Xe HPG is in the pipeline.

Intel also showed a dieshot of a Tiger Lake quadcore, the parts of which by Twitter user Locuza. Those annotations are unofficial, as Tom’s Hardware points out, but seem to provide correct insight into the placement of the four Willow Cove cores, the cache quantities, Thunderbolt 4, and the Xe LP GPU’s execution units and tmu’s. Tiger Lake is the laptop processor generation that will be released in the coming months and will be made on a new 10nm finfet process called SuperFin. The formal presentation of Tiger Lake will follow in September.

During his keynote, the Intel CEO dealt with a large number of topics in the field of chip development, including stacking dies, connecting packages and the increased influence of software. He also remembered Frances Allen, who died in early August, a computer scientist who, among other things, has done important work for the development of compilers. AnandTech has published an account of Koduri’s Hot Chips keynote.
