Intel will be releasing their Rocket Lake-S-based (RKL-S) desktop processors in the first half of next year. Little, however, is known how they'll perform and what the final clock frequencies will become. 

Rumors have shown frequencies all over the place, even running up-to 5.5 GHz. And based on 14nm production, that would entail massive power consumption no matter how we look at it. Facts are these chips have up to eight cores and 16 threads and are advancing on Comet Lake-S as a design, with new Cypress Cove cores for the CPU. Listed below would be the final clock speeds of the first RKL-S chips that will be released.

Reputable Twitterer Harukaze5719 published a table holding what should be the finals specs. Rocket Lake series Core i9 11900K would offer a single-core boost clock of 5.3 GHz, along with an all-core boost of 4.8 GHz. That's pretty similar to the Core i9 10900K, which also maxes out at 5.3 GHz. The differential is the clock speed for all cores at 4.9 GHz. That is somewhat higher. Core i7 11700K, funnily enough, is clocking 100 MHz lower for both the all-core and the single-core boost clock compared to its current-gen counterpart.

Davidbepo highlights on Twitter that there is a small error in the specifications of Comet Lake in the table. The Core i9 10900K offers a boost clock of 4.9 GHz instead of 4.8 GHz (the previous paragraph's speed is correct). He further states that the PL1 and PL2 values of 125 watts and 250 watts of the top i9 model have remained the same. The influential improvements will therefore need to come mainly from Cypress Cove cores. This is the new CPU core design for Intel desktop chips that have been using revisions of Skylake for many years, the manufacturer declares to achieve an IPC improvement of at least 10%.

Are these the final clock frequencies for Intel Rocket Lake-S Desktop processors?
