AMD Zen 3 is more efficient

At the upper end of the performance, a Ryzen 5 5950X with 16 "large" Zen 3 cores is faster with 142 watts (max. Permanent power consumption ex works) than a Core i9-12900K with up to 241 watts, so much more efficient. And in the 65-watt region, too, things will be tight for Alder Lake. Because although the Ryzen 5000 with Zen 3 cores consumes comparatively little energy under full load, this architecture can also work much more efficiently if the clock is reduced.

Specifically, this means: A Ryzen 9 5950X in Eco mode with a maximum of 88 watts beats a Core i9-12900K with 88 watts in the editorial team by 8 percent, the 65-watt configuration highlighted by Intel by 33 percent (at 35 Percent higher consumption). A test of the Ryzen 9 5950X with 65 watts is still pending, but both platforms shouldn't take much on this level - AMD's classic approach with one type of core is at least on par with Intel's hybrid approach and still clearly superior at the upper end of the performance.
