Intel provided more information on the supercomputer versions of Sapphire Rapids and Ponte Vecchio

The supercomputer version of Sapphire Rapids has 64GB of HBM2e memory in addition to DDR5 memory, and the 128 Xe core in the Ponte Vecchio includes 128 beam tracking units.

Intel has already had time to talk about its upcoming circuits on both the processor and GPU and accelerator fronts. However, the company again had a few new grains of information to share at Supercomputing 21.

Intel has unveiled the most robust version of its upcoming Sapphire Rapids server processors and Ponte Vecchio at Supercomputing. The Sapphire Rapids HBM and Ponte Vecchio are both used in Aurora’s computing anodes.

In addition to four processor chips, four HBM2e memory stacks are installed in the heaviest version of Sapphire Rapids. With four 16GB stacks of memory, the processor has a total of 64GB of high-speed memory at 1.4-1.6TB / s. HBM memory stacks are connected to process chips via EMIB bridges.


Ponte Vecchio’s revelations are also partly related to memories, but there was room for more. The chips may follow the Xe-HPC model more closely than expected, as the 128 Xe core comes with a total of 128 Ray Tracing units. Computing chips have a total of 64 MB of L1 cache and 408 MB of L2 cache. The circuits used by Ponte Vecchio are manufactured using Intel 7, TSMC N7 and TSMC N5 manufacturing processes.
