We didn't go with the 64-core chips because they have significantly lower clock speeds. Dual 32-core chips give us plenty of cores while keeping clocks higher

Dual 32-core chips give us plenty of cores while keeping clocks higher for single-threaded performance.
You are correct that the price of the CPUs is almost irrelevant to the overall cost of a system with this much memory and storage. We were picking the ideal CPU, not selecting on CPU price.
- fabian2k 6y agoThanks for the answer. I would have guessed that the higher core count outweighs the lower frequence for database usage, but obviously I don't know the details. I think the 90% CPU usage graph just made me nervous enough to want the biggest possible CPU in there.
- _joel 6y agoooi how is the NUMA on that setup? Does it still use QPI or is there a newer technology now (I've been out of this space for a few years now)
