Is there a reason why AMD hasn’t gone past dual-socket setup to allow for this type of extreme scaling? I assume it’s simply due to market size being so small

I assume it’s simply due to market size being so small for a server so large?
- wmf 3y agoAlso Infinity Fabric may have poor performance beyond two sockets.
- cosmotic 3y agoThere's a diagram at https://www.storagereview.com/news/3rd-gen-intel-xeon-scalable-cpus-are-out https://www.storagereview.com/news/3rd-gen-intel-xeon-scalab... which does a good job showing the links between individual CPUs. There's a performance penalty to access data in memory attached to other CPUs, which reduces use cases.

- fulafel 3y agoAMD had higher socket counts in earlier HW (Opterons).
