Intel takes on AMD and Nvidia with mad 'Max' chips for HPC
, have been a source of curiosity within the HPC community for years because they will power the US Department of Energy's long-delayed Aurora supercomputer, which is expected to become the country's second exascale supercomputer and, consequently, one of the world's fastest.
In case you were wondering if any server vendors plan to use these chips, the answer is yes. Intel said there are more than 30 system designs for Xeon Max coming from 12 vendors, including Hewlett Packard Enterprise, Dell, Lenovo, and Supermicro. Those will likely overlap with the more than 15 designs for the datacenter CPU Max Series coming from five vendors.
Unlike vanilla Sapphire Rapids, Xeon Max will come with 64GB of HBM2e, which will give the CPU roughly 1TB/s of memory bandwidth and more than 1GB per core.Fujitsu's Arm-based A64FX McVeigh said this configuration, called HBM only mode, can help datacenter operators save on money as well as power, and there is no need to any code changes for software to recognize HBM.
Intel shared several other performance comparisons where a Xeon Max system was anywhere from 20 percent to 4.8 times faster than an Epyc-based system depending on the HPC workload. But, as we said before, any competitive juxtaposition offered by a vendor needs to be viewed with great scrutiny., which may arrive sometime next year or 2024.
