Our institution runs multiple HPC clusters for all kinds of scientific use cases. I remember reading about the head of the HPC department making the switch from INTEL/AMD to IBM because it had a much larger memory / storage (I can't remember which) bandwidth in some astronomy application. This made the project feasible without having to invest in custom hardware.

It's good to see that POWER still excels in important use cases.

POWER9 has large cache and can take large memory (at least for when it appeared), but was particularly notable for bandwidth/latency. I think they were the first with PCIe 4, for instance, when PCIe 3 was a bottleneck for HPC interconnect.

The native interconnect in 10 looks interesting.
