Intel spills the beans on Cascade Lake

by on06 November 2018

Ahead of the annual Supercomputing 2018 conference

Chipzilla has announced part of its upcoming Cascade Lake strategy and teased plans for a new Xeon platform called Cascade Lake Advanced Performance, or Cascade Lake-AP.

The announcement comes before the Supercomputing 2018 conference where more details are expected to be announced.

Cascade Lake-AP doubles the cores per socket from an Intel system by joining several Cascade Lake Xeon dies together on a single package with the blue team's Ultra Path Interconnect, or UPI.

Intel will allow Cascade Lake-AP servers to employ up to two-socket (2S) topologies, for as many as 96 cores per server.

Intel chose to share two competitive performance numbers alongside the disclosure of Cascade Lake-AP. One of these is that a top-end Cascade Lake-AP system can put up 3.4x the Linpack throughput of a dual-socket AMD Epyc 7601 platform.

If this benchmark proves true it could hurt AMD. The AVX-512 instruction set gives Intel CPUs a major leg up on the competition in high-performance computing applications where floating-point throughput is paramount.

Intel used its own compilers to create binaries for this comparison, and that decision could create favourable Linpack performance results versus AMD CPUs too.
