Intel released model-names and clock frequencies for Kaby Lake processors by way of a Product Change Notification. We are talking about the desktop models of course, including the Core i7-7700K and Core i5-7600K.
It is now fact that Intel is to announce the new processors during CES 2017 (in January). 14nm Kaby Lake is merely a small product refresh over Skylake and will introduce some new models and alongside of it a new chipset that will unfold towards Z270, H270, Q270, Q250, B250 and C422 and X299. Kaby lake processors will however remain compatible with the current Series 100 chipset, but does require a BIOS update.

| Core i5-7500 | 4/4 | B0 | 3.4 /? GHz | 200MHz | 6 MB | 65 W |

First photos however now have surfaced on the desktop processors, in specific a Core i5-7600K. If you look at the laser imprint, this is not an engineering or Qualification Sample, instead a CPU. In addition, there are some CPU-Z screenshots available as well.
The laser imprint also shows the base-clock of 3.8 GHz Core i5-7600K processor. The Core i5-7600K is a 4 core chip without multi-threading support. This chip has 6MB of L3 cache and 95W TDP. Base clock is 3.8GHz and is capable of boosting to greater than 4GHz. The Kaby Lake desktop processors will release early 2017 although the corresponding Z270 chipset motherboards might come out before that.
Core i5 7600K 3.8 GHz – Overclocked to 5.1 GHz
The Core i7 7700K listed would be a quad-core with HyperThreading enabling 8 logical CPUs. The clock frequencies have changed towards higher numbers though. As it stands now this flagship quad-core processor is clocked at 4.2 GHz and can Boost to 4.50 GHz. To compare a little, a Core i7 6700K runs at 4.00 GHz with a boost to 4.20 GHz. The cache is the same, 256 KB per-core L2, and 8 MB shared L3 caches. Clock-for-clock and core for core you should not expect much performance differences though. The processors will use the current socket LGA1151 which means that after a motherboard firmware upgrade, you should be ready to go with your current motherboard. The second K model would be the Core i5-7600K and will get a 3.80 GHz clock that may boost towards its 4.00 GHz Turbo. It will have less L3 cache (6 MB) and also will lack hyper-threading. Lower in the stack will be lower TDP based SKUs like the i7-7700 (non-K) with a 3.60 GHz base clock and TBA turbo clock.
