Some Intel documentation surfaced on the pending Core i9 9900K and i7 9700K, while most information was already publicly available, the slides also show the various turbo clock frequencies, and they certainly are interesting.
The Core i7 9700K is an eight-core and eight-thread processor (that's right no Hyper threading) with a boost up to 4.9 GHz on one single-core. However, it can turbo at 4.6 GHz maximum on all cores.
Intel's soon the be most high-end desktop processor the Core i9-9900K is the same 8-core part, yet now with HyperThreading enabled (16-threads). This processor has some interesting stuff, it can do 5.0 GHz on a single and dual-core turbo frequency. Also really interesting, it'll do a boost up to 4.7 GHz on all cores. That's pretty huge, to be honest. Let's hope the leaked slides are actually valid ones, the originate from PTT(Benchlife).
Core i9-9900K and i7-9700K turbo clocks revealed - 4.7 GHz with all eight cores
