Intel Announces 8 Core I9-9900KS: Every Core at 5Ghz, All the Time

Last year, Intel showcased a CPU during its keynote a processor with all of its cores at 5 GHz. Technically the CPU has a base frequency of 4.0 GHz, however it will only ever go down to that amount based on a default Intel BIOS (no consumer board uses the base BIOS specifications).

The main difference compared to the Core i9-9900K is currently that all-core turbo value, which is a flat 5.0 GHz, a 300 MHz increase.
