Not sure what you're talking about - in aws x86 you pay by core (well as much as pay by core with arm anyways, you can't just buy a 1gb server with 64 cores)

- mattashii 4y agoAWS x64 'cores' are the virtual cores you see on hyperthreaded CPUs and map 2:1 to physical cores on the CPU, but the AWS ARM offering doesn't have hyperthreading, so the virtual cores map 1:1 to cpu cores. You can disable hyperthreading on the x64 instances at the cost of halving the number of cores you have available in the instance that you paid for.
- guipsp 4y agoYes, but this doesn't really matter - just multiply the cost by two in your accounting. Its not like you one get one core with 15 hyperthread cores
