1 "So "four channel optimised" means "eight channel but you will get a few percent better performance on some workloads if you only populate four of the channels, maybe"."
Sounds similar to Threadripper first-gen, although not quite the same due to the IOD, which wasn't in Threadripper first-gen.

2 Yeah, it's basically an inversion of the 2990WX with the same effects on latency.  The 2990WX had four CPU chiplets with memory only locally attached to two because it didn't have enough memory channels.  These have two CPU chiplets and only have the memory is locally attached because they have too many memory channels.


A Linux kernel patch will probably show up that mitigates it.  The 2990WX ran much better under Linux than under Windows as it was.
