Filtered frequencies of intel kaby lake processors

Intel Kaby Lake-S processors are the desktop versions of Intel's new generation of seventh-generation chips. These new processors are manufactured using a 14+ nm process that has reached its maximum maturity, so it can offer superior performance to its Skylake-S predecessors without increasing power consumption.

Intel Kaby Lake-S features

Optimizations in the manufacturing process and in the microarchitecture itself have enabled Intel to offer new silicons with operating frequencies that exceed 100-300 MHz of their equivalents from the previous generation Skylake. All this taking into account that we always talk about the base frequencies since the frequencies in turbo mode are still unknown but surely there is also a notable improvement in that regard.

We recommend our guide to the best processors on the market.

The most powerful Kaby Lake-S processors will be the -K models with the multiplier unlocked and a TDP of 95W. Below are the versions with the multiplier locked and the T-versions that are the most energy efficient, their TDPs will be 65W and 35W respectively. The following table shows all the leaked features of the Intel Kaby Lake-S processors compared to their predecessors the Skylake-S.

Intel Kaby Lake-S will be compatible with the current 100 series motherboards that came along with Skylake-S through a BIOS update, however to take full advantage of its features it will be best to opt for a new 200 series motherboard with support for the latest technologies like Intel Optane.
