Sapphire Rapids with High Bandwidth Memory openfoam benchmark

"In the benchmark, the Sapphire Rapids-SP non-HBM solution offers up to 60% higher performance than Ice Lake-SP while the HBM Xeon solution offers up to 180% performance increase. The same is true when comparing the chip to AMD's EPYC Milan lineup"

Obligatory "first party benchmark with very little information about the actual procedure" reminder

But yeah, Sapphire Rapids should make the switch to 8-channel DDR5 memory. That's at least a 50% increase in memory bandwidth compared to current-gen CPUs. So the 60% performance increase without HBM sounds plausible.
The next CPU generations from both Intel and AMD will be very exciting. AMD allegedly more than doubles memory bandwidth with 12-channel DDR5 on Genoa. And both companies will implement some variation of huge last-level caches. Can't wait to see how these solutions perform. And if I will be able to afford any of that for my personal workstation. Provided we can even get our hands on them.
