Intel Ice Lake-SP faster than AMD EPYC with half the cores?

Intel Ice Lake-SP faster than AMD EPYC with half the cores?
On the occasion of the Supercomputing 2020 event, Intel revealed some details regarding its third generation Xeon scalable processors 'Ice Lake-SP' which will be officially launched during the first quarter of 2021. Among other things, Intel shared some preliminary performance data and said that a server equipped with two 32-core Ice Lake CPUs is faster than a machine based on two 64-core EPYC processors from AMD.

Intel's upcoming third-generation Xeon Scalable processor will feature up to 32 cores and eight memory channels that will support up to 6TB of DDR4-3200 and Intel Optane. Additionally, the new CPU will support PCIe 4.0 connectivity and a host of new security technologies, including cryptographic accelerators.

Intel says the new Sunny Cove microarchitecture, coupled with special accelerators and extended memory support, will allow the new processors to be significantly faster than their predecessors based on the now rather obsolete Skylake microarchitecture.

According to the company, a server equipped with two third-generation 32-core Xeon scalable CPUs clocked at 2.20GHz coupled with 256GB of DDR4-3400 memory is from 20 % to 30% faster in select benchmarks (LAMMPS, NAMD STMV, Monte Carlo) than a server equipped with dual 64-core AMD EPYC 7742 processors clocked at 2.25GHz and 256GB of DDR4-3200.

Intel has yet to officially unveil its "Ice Lake" third generation Xeon scalable processors, but a number of customers including Korea Meteorological Administration, The Max Planck Computing and Data Facility, The National Institute of Advanced Industrial Science and Technology (AIST), the University of Tokyo, the University of Osaka and Oracle, have already announced their intention to use the new CPUs for their HPCs.

We remind you that recently it was first benchmark running on a Tiger Lake-H processor, designed to be used in high-end notebooks and compact low-power, eight-core desktops.
