Intel Core i5-7600K Tested, Negligible IPC Gains
Ahead of its launch, a Core i5-7600K processor (not ES) made its way to Chinese tech publication PCOnline, who wasted no time in putting it through their test-bench, taking advantage of the next-gen CPU support BIOS updates put out by several socket LGA1151 motherboard manufacturers. Based on the 14 nm "Kaby Lake" silicon, the i5-7600K succeeds the current i5-6600K, and could be positioned around the $250 price-point in Intel's product-stack. The quad-core chip features clock speeds of 3.80 GHz, with 4.20 GHz max Turbo Boost frequency, and 6 MB of L3 cache. Like all its predecessors, it lacks HyperThreading.
In its review of the Core i5-7600K, PCOnline found that the chip is about 9-10% faster than the i5-6600K, but that's mostly only due to its higher clock speeds out of the box (3.80/4.20 GHz vs. 3.50/3.90 GHz of the i5-6600K). Clock-for-clock, the i5-7600K is just about 1% faster, indicating that the "Kaby Lake" architecture offers only negligible IPC (instructions per clock) performance gains over the "Skylake" architecture. The power-draw of the CPU appears to be about the same as the i5-6600K, so there appear to be certain fab process-level improvements, given the higher clock speeds the chip is having to sustain, without a proportionate increase in power-draw. Most of the innovation appears to be centered on the integrated graphics, which is slightly faster, and has certain new features. Find more performance figures in the review link to PCOnline below.

Also Sandy Bridge was launched in 2011...
Also keep in mind that you get other new technologies by upgrading, such as native USB 3.0, USB 3.1, M.2 and so on.
That said, you're right in saying that Kaby Lake is disappointing overall from a CPU perspective, as the improvements all seems to be on the graphics side, which I presume most of us here on TPU don't care much about.
I might actually side grade to a Skylake if it gets price drops when Kaby releases or if Zen is AWOL or underperforms.
One factor we don't yet know is if Kaby can hold higher overclocking frequency. If Kaby can go to 5Ghz, the that might make it another far favourite. But we don't know these things yet.
Everyone with half a brain knew Kaby Lake was not going to be anything interesting *at all*. Kaby Lake is Intel postponing their shit just a bit more and that is all she wrote. Basically, Skylake confirmed that Intel lost its mojo as far as CPU is concerned. Its underwhelming, and it is the architecture taxed to capacity. Intel needs to add cores to mainstream, it is the only way they now have to improve package performance apart from just raising clockspeeds. And they will, apparently Coffee Lake will be having 6-core mainstream CPUs.
Tick-tock-'optimize' said Intel... and people believed it was going to be great.
LMAOIf... I think what we are seeing here is Intel doing a Nvidia Pascal. The process allows for higher guaranteed clocks and those are directly taken away from its OC capability. The CPUs already have turbo and the clockspeed ceilings have not been going up across the board, but only very situationally. Sandy still clocked as good or better.
It doesn't matter what they have/had or do, the fact is that AMD will be always 3 steps back to Intel.More than you and enough to know that AMD won't never catch Intel.
But after that AMD has not do anything worth in order to keep in competition with Intel, even it looks like year after year AMD is getting worse and worse, their last chance is Zen and let's hope for those AMD believers that this time they go back in the Game.
So I aint never not going to dis what you aint not written.
