Intel’s 11th Gen Rocket Lake-S Processors May Draw 250W+ Under Load: 251W for 8 Core; 191W for 6 Core

It turns out that Intel’s 11th Gen Rocket Lake-S desktop processors may be even more power-hungry than the newly announced Comet Lake-S parts. This isn’t that far-fetched as it’ll be another 14nm based design, however, with the Willow Cove (or perhaps Sunny Cove) core architecture. Intel is reportedly going to backport the Willow Cove design from 10nm++ to its 14nm class process. This is the first time anyone has attempted this, so we’re not sure how the thermals and power draw of the resulting processors will be like. According to Sharkbay, a well known Taiwanese source, Rocket Lake-S will top out at eight cores with a maximum PL2 power draw of 251W.

The marketed TDP of the 11th Gen RKL-S flagship (most likely 11th Gen Core i9) is rumored to be 95W, less than that of the Core i9-10900K, but the PL2 (load) power consumption is nearly the same at 251W. This isn’t particularly encouraging news as Rocket Lake-S will most likely top out at eight cores.

Furthermore, the TDP of the six core parts (11th Gen Core i7/i5) is suggested to be 191W, much higher than that of the existing hex-core offerings. Lastly, the quad-core designs (11th Gen i3s) will have a PL2 power draw of 146W.

Why do Intel CPUs (Core i9-10900K: 250W) Draw a Lot More Power than the Spec TDP: A Look at PL1, PL2 and Tau

Like the 9th and 10th Gen lineups, the 11th Gen Rocket Lake CPUs will have a cTDP mode that will reduce the PL1 value (spec TDP) to 80W for the 8-core flagship with the PL2 remaining the same at 251W. For the six-core and quad-core parts, the PL2 is supposed to be ~170W and 128W, respectively. The Tau in case of the Intel desktop chips is mostly irrelevant as OEMs usually override it, so I left it out. Keep in mind that these values pertain to the unlocked K series SKUs.

The same source further alleges that the 12th Gen Alder Lake lineup that is expected to be the 1st desktop stack based on 10nm will leverage DDR5 RAM along with PCIe 5.

Please take this with a grain of salt. Even if its true, the 11th Gen Rocket Lake CPUs are quite a ways from launch, so some of the specification may change.
