Ditching hyperthreading in server processors would create an interesting pricing/communication challenge for cloud providers. Currently, they tend to sell single hyperthreaded cores as if they were two cores.
- kd913 3y agoThat is the current graviton model right? They beat on price and energy with no SMT. This should be ok I assume in a similar vein if you can stuff as many cores as possible.
- wmf 3y agoNot really; they sell each x86 core as two vCPUs. There could be some confusion if a new generation has fewer vCPUs but better performance. Customers should do their own benchmarking but I'm sure many of them don't bother and just choose VM types based on specs.
- freedom-fries 3y agoNo. Due to spectre and other similar issues, all of them (at least all the sane ones) sell cores, but will count each core as either one "core" or more commonly two "vcpus".
