I wonder how much does Arm save data centers in electricity and CPU cost. Not only cheaper to fabricate but also cheaper to run?

- tuetuopay 3y agoA 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.
