Those Fujitsu chips are fascinating. They are ARMv8 like a smartphone, but the architecture is allegedly derived from SPARC HPC chips, and they have fat 512-bit vector units. And instead of DDR4, they use HBM as system memory. This has some significant advantages over the classic CPU + GPU architecture, hence the US Department of Energy had very nice things to say about them: https://www.osti.gov/servlets/purl/1831598 https://www.osti.gov/servlets/purl/1831598 They are getting a bit long in the tooth, so Sapphire Rapids probably makes more sense unless Fujutsu updates them (or they get access to the ARM chips SiPearl is cooking up in Europe).
