It operates at a base clock of 4.0GHz and the maximum Turbo frequency has been capped at 4.2GHz. The 6700K features 16 PCI Express 3.0 lanes which means a single GPU can connect to the CPU in a 1x16 configuration, while two-way Crossfire or SLI will use the 2x8 configuration.

Reviewers Liked

  • Quickest Intel quad-core yet
  • Support for DDR4, as well as DDR3 in its low-voltage flavour
  • Reasonable IPC improvement
  • Good performance in gaming (excluding early software bugs), especially when factoring in the i5-6600K's pricing

Reviewers Didn't Like

  • Not a major upgrade over the i7-4790K
  • Expensive
  • Intel's product strategy has gone walkies
  • Needs a new platform
  • 20 PCIe 3.0 lanes on the CPU would have been better for two graphics cards and a low-latency PCIe SSD

Though there are still some hotly anticipated titles due in 2016, we might already have the game of the year on our hands. Overwatch has been on our radar for a while now but it recently blew up in a big way with an open beta that attracted over 9...

Those with a Sandy Bridge processor might be tempted, though we suspect 2500K owners will hold out for a more substantial upgrade. Just last week we revisited older Intel CPUs and found that some four-year-old Sandy Bridge models still had plenty of life left in them, not including their overclocking potential.

Last month we finally got our first look at Intel's latest 14nm technology for desktop computers when we reviewed the Core i7-5775C, codenamed Broadwell. Intel's transition to the 14nm node was difficult and as a result Broadwell processors were delayed...

We recommend the Intel Core i7 6700K over all other currently available processors in the market. At the price point it currently retails at, the 6700K outperforms competing models and manufacturers in several departments. 14nm construction, power...

Now that the new 7th generation Intel Core i7-7700K has been tested against the previous 6th generation Intel Core i7-6700K at the same clock speeds (4.5GHz), I have come to my overall conclusion. There is no actual performance increase on the IPC and...

Its performance gains may be modest, but the Core i7-6700K is definitely exciting on the overclocking...

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.

There’s no doubt that in terms of single and multithreaded and performance, Intel’s Core i7-6700K is the best quad-core chip on the market. In a high-end consumer PC, particularly for gaming, there’s nothing better. If you’re shopping for a new desktop PC, get one with a Skylake chip.

As an enthusiast, I am excited for what Skylake brings to the table. And yes, we might finally have a part that gets those Nehalem and Sandy Bridge users off their butts and into the upgrade line.

The Core i7-6700K is at the vanguard of the 2015 Skylake rollout, and while it's better than the popular Core i7-4770K/4790K in every way whilst costing about the same, the improvement isn't nearly as much as we were hoping for. Still, thinking of building a new PC platform and want it as futureproof as possible? Skylake is where you start.

The Intel Core i7-6700K Skylake processor is a very capable processor that has respectable performance at stock speeds and was able to overclock up to 4.7GHz and turn in some rather impressive benchmark numbers
