So they have experience with high bandwidth memory. They clearly have decided it’s not worth the trade-off. The A64FX, at 32GB over 48 cores gives you less than 700MB per core to work with. It’s fast, but if your code ENOMEMs, fast doesn’t help.

For an all CPU design it would have been much more exciting to get the Fugaku chips, with perhaps a dash of SerDes wasabi for doubling the size of the directly-connected high-bandwidth memory.
