Both AMD and Intel have released some truly impressive CPUs lately, and this month both of them are releasing their next-gen products (ryzen 7000 and raptor lake respectively, I believe). The new ryzen chips are looking very impressive, and if Intel’s announced numbers are to be believed, raptor lake is going to be pretty great.
Where they fall down is on perf/watt, not raw performance. However there’s a lot of things that go into that difference, not just ISA, so I’m not sure if anyone has really decided if x86 is fundamentally less efficient, or just currently less efficient due to current design choices and constraints.

In just one generation they are claiming similar perf to Alder Lake at 250W but just 65W on Raptor Lake. AMD did a similar huge jump in efficiency last year with Ryzen 6000 for mobile
- KingOfCoders 4y agoIntel x86 will make even greater leaps in the future. The eCores (where they added more this generation, but no (?) pCores) are as small as ARM cores and the saved die space can be used for chaches (Intel already increased caches again on Raptor) for performance and power efficiency (as Apple shows). Then there will be 5nm which is a big reason for Apples Perf/Watt performance.
