TechPowerUp published Intel Rocket Lake-S i9-11900K, i7-11700K, and i5-11600K Specs Confirmed, Native DDR4-3200 Support A quote from the article:

A leaked marketing slide from MSI Japan confirmed specifications of three 11th Gen Core "Rocket Lake-S" desktop processors that gamers and enthusiasts have their eyes on—the flagship Core i9-11900K, the next-best Core i7-11700K, and the performance-segment Core i5-11600K. The slides confirm that both the i9-11900K and i7-11700K are 8-core/16-thread parts, while the i5-11600K is 6-core/12-thread. With the "Rocket Lake-S" die capping out at 8 cores, Intel's product managers have lesser wiggle room to segment the Core i7 part from the Core i9 flagship.
