Yes, so then why are ARM chips in mobile devices approaching x86 performance with an order of magnitude less power?

- rayiner 7y agoThat’s not the reason, especially not in this day and age of clock gating. It’s because those ARM designs are optimized for low power, at the expense of not having headroom to take advantage of higher power envelopes if they are available.
