Intel Rocket Lake-S Core i9-11900K CPU Detailed Specifications Including 5.3 GHz Boost Clock Leaks Online

Intel’s 11th-Gen Rocket Lake Series of CPUs have been steadily appearing in leaks recently. The Intel Rocket Lake-S Core i9-11900K CPU was the latest to surface online in the form of Ashes of the Singularity benchmark. Back then, the information obtained from the AotS website was scarce. However, a Twitter user has offered multiple details of the powerful, flagship processor from Intel.

The flagship Rocket Lake-S CPU leaked earlier this month. However, the AotS website does not offer information about the maximum turbo frequency. But several pieces of information have once again surfaced online offering a complete picture of the flagship CPU from Intel’s upcoming family of processors that will have a new core design called Cypress Cove.

Intel Rocket Lake-S Core i9-11900K CPU Specifications, Features:

The flagship Intel Rocket Lake-S Core i9-11900K CPU has a single-core Thermal Velocity Boost (TVB) frequency of 5.3 GHz. The tipster adds the CPU has an all-core TVB frequency of 4.8 GHz. While the single-core frequency is identical to the 10th-Gen Intel Core Series flagship, the Intel Core i9-10900K, the all-core speed is actually lower by 100 MHz.

The CPU reportedly has a maximum PL1 (Power Level 1) of 125W and PL2 of 250W. These are identical to the 10-core Comet Lake-S flagship as well. The PL1/PL2 data for the rest of the Rocket Lake-S lineup currently remains unknown.

Interestingly, the Thermal Velocity Boost could remain exclusive to the 11th-Gen Core i9 series. This means the frequencies could merely indicate the highest frequency the CPU can achieve. However, this means there’s uncertainty about Turbo Boost 2.0 and Max Turbo Boost 3.0 frequencies.

Another Twitter user has come up with a spec sheet based on the most recent rumored specifications. The chart appears to be quite accurate, except for the TVB support on the Core i7 series.

The chart is obviously an oversimplification because Intel has many different boost states and technologies. These will obviously not be mentioned under a single umbrella or a single type of boost. A simple example is that TVB is meant only for the Core i9 Series, but only Core i7 SKU should support Turbo Boost Max 3.0

Intel Rocket Lake-S utilizes a new core design called Cypress Cove. However, Intel is still sticking to the archaic 14nm Fabrication Process. Still, the 11th-Gen Intel Rocket Lake will be the company’s first non-Skylake architecture since 2015. Incidentally, this will be the last Intel CPU family to work with DDR4 Memory.

The only advantage of the Intel Rocket Lake-S Core Series appears to be support for PCI Express 4.0 on the mainstream platforms. Moreover, this series will be the first to integrate Intel’s own Gen12 Xe Graphics, branded as Intel Iris. These new CPUs will work on the currently available 400-Series motherboards with LGA 1200 sockets. The company is working hard to ensure the new 500-Series of motherboards are available early next year.

These CPUs will be quickly succeeded by the Alder Lake-S series which would be inserted inside the LGA 1700 socket. These processors will have DDR5 support and arrive by the end of 2021.
