A lot, and that's why cloud providers push them so hard. I'd bet that AWS has more margin on those Arm instances than on x86. Much cheaper to run, a discount for the client, and everybody saves money. Random numbers: - an Ampere Altra Max Q80-30 (80 cores) has a 210W TDP - for the same power draw, you get an AMD EPYC 9334 which is a 32c64t monster At 2.5x the core count, even if the ampere ones are less powerful, there still is a huge gap. Those are not the CPUs used by AWS but this still gives us a ballpark: there is a substantial performance gain at the same power target, or a substantial power savings at the same performance target.
