Intel 10nm ESF Node 30% More Efficient than 14nm: Core i7-12700K vs Core i7-11700K PPT

Intel’s Alder Lake-S CPUs represent the first desktop lineup from the chipmaker to finally ditch the (nearly) decade-old 14nm process. Although the chips are a big step up from Rocket Lake in terms of sheer performance, the power efficiency leaves much to be desired. This is doubly true since the company renamed its 10nm ESF node to Intel 7. Tests conducted by @Raichu show that the Core i7-12700K when run with the efficiency cores disabled at 4.2 GHz (at v1.012) is nearly 30% more efficient than the Rocket Lake-based Core i7-11700K.

The 10nm Enhanced SuperFin process is more or less the same as the 10nm at least in terms of PPT. With a power draw of 90W at 4.2GHz, the Core i7-12700K (Alder Lake-S) is roughly 30% more efficient than the Core i7-11700K (Rocket Lake-S) at 118W. The Core i9-9900K (14++) with a power draw of 125W is 40% more power-hungry than the 12700K and a minor 6% more than the 11700K (14nm++++).
