TCO is supposedly becoming an increasingly dominant metric in the sever space, of which FLOPS/watt is probably more important than IPC. So in many server segments a class-leading "WPI" (we need some kind of name) with decent IPC could actually lead ARM to victory.
- white-flame 12y agoRealistically, how important is FLOPS to most servers? File servers, web servers, database servers, authentication servers... none of them tend to be heavy on floating point. Sure, HPC is all about FLOPS, and desktops tend to use quite a bit for presentation nowadays, but I would consider memory bandwidth, I/O bandwidth, thread scaling, and single-thread performance non-FP metrics such as branch latency to be much more important in the general server market.
- sliverstorm 12y agoFeel free to mentally insert your performance metric of choice. FLOPS, IPC, branch latency, etc. There is no one all-encapsulated benchmark that I know of. I say "FLOPS" as an artifact of the past.
- ksec 12y agoWell I dont think TCO really flavor ARM at all. If you look at Server as a whole, putting in the ECC RAM, HDD or SSD and Network, the CPU power/performance scaling work much better in Intel's flavor.
