It looks like Intel has increased the power draw of its 11th Gen Rocket Lake-S CPUs despite a reduction in the maximum core count from ten to eight. Both the octa-core and hex-core processors have had their PL1 and PL2 power limits pushed up compared to their predecessors. The same is true for the T series (low-power) lineup which comes with a marketed TDP of just 35W:
The top-end Core i7 and Core i9 parts of the Rocket Lake-S lineup have a PL1 power target of 125W, same as their predecessors, but the PL2 (load) values have been increased to 251W, with reviewers reporting a power consumption close to 300W in AVX512 workloads. The base PL2 value has increased from 177W on the Core i9-10900K to 203W on the 11900K despite the latter featuring two fewer cores. (divinewoodncrafts.com) Moving onto the 65W octa-core offerings, the PL1 and PL2 performance values are the same as their 10-core predecessors, with the base PL2 value reduced by 22W.
On the other hand, the hex-core 65W offerings ( non-K series Core i5s) have had their PL2 performance value bumped up from 134W to 154W. The base PL2 value, however, has been reduced to 119W, although, I’m not sure whether this will actually have an impact on the real-world power draw (under load).
The next is the 35W T series lineup. Where the 10-core Comet Lake-T SKUs had a PL2 base and performance limit of 92W and 123W, Rocket Lake-T has an ever so slightly lower rating of 84W and 115W. Finally, we’ve got the hex-core 35W offerings which also see a slight drop in the PL2 value (~8W).
