Intel Core i7-7700K "Kaby Lake" SANDRA Scores Surface
Someone with access to a Core i7-7700K "Kaby Lake" processor and an ASRock Z270-Extreme4 motherboard put the chip through SiSoft SANDRA 2015 CPU tests. Engineering sample or not, the clock speeds of the chip appear to check out with those of the lineup as we know it. The core ticks at 4.20 GHz, with a maximum Turbo Boost frequency of 4.50 GHz. You also get 8 MB of L3 cache, and HyperThreading. The benchmark confirms that Intel is working on a new platform refresh chipset, with the Z270 chipset succeeding the existing Z170. Existing LGA1151 could support the new chips, with BIOS updates.
At its stock speeds, the i7-7700K churns out a SANDRA 2015 "Processor Arithmetic" score of 151.94 GOPS. Its "Processor Multimedia" score yielded is 379.8 Mpix/s. To put things in perspective, a Core i7-6700K "Skylake" processor running at its stock speed of 4.00 GHz core with 4.20 GHz Turbo Boost typically yields 140.88 GOPS in "Processor Arithmetic" and 353.8 Mpix/s in "Processor Multimedia" tests, according to LegitReviews. Intel is expected to launch the 7th generation Core processor family, alongside the 200 series chipset, later this year. Kaby Lake is Intel's third CPU micro-architecture for the 14 nm process, after "Skylake" and "Broadwell."

First year of CPU life, the new CPUs are generally less than 5% of all CPUs Intel produces that year.
Also, I own both, Intel and NVIDIA. Must be AMD fanboy, right?
its stupid? Like cadaveca said they have had new CPUs and chipsets to go with each new CPU line up release. Nothing has changed. And why should it? Software hasnt gotten very far to warrant any huge break throughs in cpu performance, and Intel has zero competition. Intel could literally sit on Skylake for a few years, but they have to do something to keep the investors happy.
If Intel had any competition the fate for K CPUs would be the same but other non-K CPUs would get higher frequency raise than they do currently annually.
7.35% more Mpix/s
5.00% higher clockspeed
So, in terms of IPC, Kaby Lake is only 2.35-2.85% faster than Skylake which begs the question, "why does Kaby Lake exist?" There's no doubt in my mind that Intel could sell a Skylake 6750K with 4.2 GHz clock speed defeating the purpose of introducing another architecture.
Just going to bump my clock speed a bit and I'll have the same performance :-)
....and stay in business....
