Intel Kaby Lake Processors Confirmed in Product Change Notification

Intel Kaby Lake Processors Confirmed in Product Change Notification

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.

Earlier leaked info indicated the following:

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.

Even at 35 Watt there will be a Ultra Low Power quad-core processor, the Core i7-7700T will have 2.90 GHz clocks and 8 MB of L3 cache. More SKUs can be spotted in the table, courtesy of OCaholic.

Need a definition of Stagnation? ^ This.

Waiting for 10nm CPU's. And fingers crossed for them to be stock 5.0ghz.

Please stop showing us pictures of overclocks with such insane voltages, I cant bare looking at it!

1.5 is like OUCH! However temps look fine, i wonder if its that cool, or that is literally super idle. And goes to like 90c during load. :wanker:

Hmm, if we look into it for the last 5.5ish years(since Sandy Bridge), Intel -K CPU's usually max out about at 5-5.1GHz@~1.50v. With a few exceptions here and there of course.

Might be nothing but it just came to my mind when I saw that 7600k voltage. I guess we are hitting those power/thermal walls pretty hard. :P

Was going to say this, it's starting to feel a bit like the P4 era.
