An internal MSI document has spilled the beans about three Intel Rocket Lake-S processors, the Core i9-11900K, Core i7-11700K and Core i5-11600K. It reconfirms reports from earlier, stating that the Core i9-11900K and Core i7-11700K would come with eight cores and sixteen threads, while the Core i5-11600K will serve as six-core, twelve thread CPU. It also sheds some light on the processor's base clock, boost clock, L3 cache, etc.

Intel's 11th-generation Rocket Lake-S line of desktop processors has been in the limelight for quite some time thanks to a slew of leaks. A new report from Videocardz sheds some light on what some Rocket Lake-S SPUs have in store for us; specifically the Core-i5 11600K, Core-i7 11700K and Core-i9 11900K. The leak essentially reaffirms what we already knew about the processors.

For starters, the Intel Core-19 11900K will come with eight cores and sixteen threads, 16MB of L3 cache and 4MB of L2 cache. It is clocked at 3.5GHz out of the box and can turbo up to 5.2GHz. Intel's Thermal Velocity Boost allows those number to go as high as 4.8GHz across all cores and 5.3GHz on a single core. Lastly, the Core-19 11900K has a TDP of 125W and is compatible with 3,200MHz DDR4 RAM.

A recent Geekbench listing told us that the Intel Core i9-11900K is up to 32% faster than its predecessor, the Core-i9 10900K. It even managed to trounce the AMD Ryzen 9 5950x in single-core performance. However, PassMark tells us a different story, with the high-end AMD CPU managing to outperform the Core-i9 11900K.

The Intel Core i7-11700K is identical to the top-of-the-line Core-i9 11900K when it comes to core count, RAM support and L2, L3 cache and TDP. The critical difference lies in the base and boost clocks set at 3.6GHz and 4.9GHz, respectively. Some time ago, a report told us that the i7-11700K fell short against the AMD Ryzen 7 5800X on Geekbench. On the flip side of thing, the Intel chip seems to fare a lot better on PassMark.

Lastly, the middle-of-the-pack Intel Core i5-11600K will feature six cores and twelve threads. L3 cache is reduced to 12MB too. The processor is clocked at 3.9GHz and can turbo up to 4.9GHz. It is compatible with DDR4 3,200MHz RAM and has a TDP of 125W. Not a whole lot is known about this particular Rocket Lake-S SKU, but we can expect it to trade blows with the similarly-specced AMD Ryzen 5 5600X.
