I am not sure of the price of the 6700K, but I do think Intel will price it aggressively (between 4770K and 4790K) considering it is a mainstream part and doesn't carry any expensive silicon like eDRAM (hint: 5775C). That being said, I feel like Intel hit their CPU and GPU performance improvement targets. From my numbers, I would estimate that Intel made a 5-10% IPC improvement in CPU performance and 10-25% in integrated GPU improvements. Combine the IPC improvements with a 4GHz base frequency and some pretty awesome overclocking, and I think Intel has a winner on their hands.
In fact the consistency of their releases is unquestionably the key element. Whereas a decade or so ago there were always caveats, nowadays every processor is so well rounded that there is very little to say beyond the obvious 'it's excellent' mantra. If you'll allow us to divert for a moment there is an expression amongst guitarists called GAS. Guitar Acquisition Syndrome. No matter how good the axe you own is, the new ones always leave you reaching for your wallet. A similar statement (PAS?) would hold true with new Intel releases. Even if you own an i7-4770K it's difficult to look at the capabilities and overclocking potential of the Skylake CPUs and Z170 chipset and not find yourself thinking it's about time you upgraded.
Those overclocking capabilities are probably the star of the show. If you've been tinkering with CPUs for as long as we have then you'll remember the delicate balancing act between FSB/BCLK and the CPU multiplier. Trying to extract as much performance from all your hardware as possible. When the BCLK was locked it was a shock to the system and we all learnt new ways of overclocking. Gradually Intel have freed up that feature again from big steps (100/133/166) to today's Skylake SKU which frees you up to overclock in whichever manner you choose. It's largely why we did a 200x20, just for old times sake. Combining this BCLK freedom with the insane memory performance really sets things apart though. Our i7-6700K was running and 4.8GHz CPU 3.6GHz Memory. Even the i5-6600K had 4.75GHz/3.3GHz available. If that doesn't excite you we're not sure what will, particularly in light of how these big clocks responded in our benchmarks.
The Core i7-6700K has a lower Turbo Boost ceiling than Core i7-4790K. But its superior IPC translates to better performance in most single- and multi-threaded workloads. Under the heaviest tasks it typically only trails six- and eight-core Haswell-E parts. Of course, the benefit of Intel's mainstream platforms is their more modern feature sets. So do you want all of the features I just listed off, or do you need lots of processor-based PCIe and more cores?
Intel will go into more depth on Skylake during IDF later this month, and I don't see any reason to rush into a purchase before then (provided processors surface for sale right off the bat, that is). Should everything we learn support the data we generated today, then I think it's safe to say Skylake will become the first architecture to really get enthusiasts excited since Sandy Bridge-and not even entirely because of the processors themselves.
I like Skylake, a lot. Outside of the performance and connectivity benefits that it offers, Skylake is the most mature launch platform that I have ever worked with. The Intel Core i7-6700K and i5-6600K and new Z170 motherboards should give Sandy Bridge users a perfect place to jump off into the cool cool Skylake waters without concern.
Intel is bringing clarity to the 2015 premium consumer processor lineup with the launch of the Skylake-based Core i7-6700K and Core i5-6600K.
Though not quite ready to reveal the secret sauce that powers these two processors that harness a revised architecture, Skylake performance is a small step up from the Haswell, Ivy Bridge and Sandy Bridge CPUs many users have been clinging on to.
Be aware that being invited to the Skylake party requires further investment in a Z170 motherboard and, most likely, DDR4 RAM, with the latter not widely available in 8GB sticks just yet. The outlay is considerable, dampening the excitement that often greets a new architecture, but early adopters will receive ancillary benefits such as dedicated PCIe lanes to super-fast storage and that extra dollop of performance which regular Haswell cannot deliver.
It could be successfully argued that Intel hasn't pulled out any of the stops with desktop Skylake because it doesn't need to. Rival AMD is, for now, releasing its own incremental updates to APUs whose CPU performance is shattered by four-year-old Sandy Bridge, while the long-in-the-tooth FX series is compromised by a chipset that is out of date.
No enthusiast would have batted a lid if Intel had seen out the year with Haswell-based processors - they are plenty fast enough, while X99 retains the performance crown without a serious challenge - but Skylake finally brings DDR4 and a decent chipset to the masses.
The Core i7-6700K is at the vanguard of the 2015 Skylake rollout, and it's better than the popular Core i7-4770K/4790K in every way whilst costing the same. Thinking of building a new PC platform and want it as futureproof as possible? Skylake is where you start.
KitGuru says: Skylake is towards 10% faster than the Haswell architecture and offers consistently positive overclocking gains. Despite tough pricing competition for the flagship i7-6700K, the overall platform and its capabilities are where Skylake shines.

If the power included in the overall consideration with which predecessors have little chance. A 20 to 30 percent lower power consumption can book the Skylake processors against the direct predecessor. In particular, the Core i5-6600K offers excellent differential values that do not exceed 60 watts. The increase in efficiency is sometimes massively, when the comparison is made with the predecessor.
