What’s the Intel Core i7-7700K?
The i7-7700K may be the most effective processor of Intel’s new “Kaby Lake” generation of desktop processors. A primary successor to the Skylake 6700K, this new model advantages from higher clock speeds, improved graphics performance and a slightly better architecture.

Intel Core i7-7700K – Specifications, Technology and Chipset
The seventh generation of Intel Core chips should give you a minor improvement on the sixth-generation processors. There were no wholesale changes regarding physical design; the chip has been produced using largely the same 14nm (nanometre) fabrication process as the fifth- (Broadwell) and sixth-generation (Skylake) chips.

In simple terms, small the process, the better and for that reason powerful a processor could be. Intel calls the procedure applied to Kaby Lake chips “14nm+”, with every individual transistor profiting from a taller, thinner design for increased efficiency.

With the i7-7700K, we are able to measure just how much of a noticable difference Intel has made out of Kaby Lake: it’s the most effective chip in the marketplace with all the current features you’d expect of a desktop processor.

Those buying significant speed boost will be disappointed, however, and anybody owning a sixth-generation i7-6700K could have few reasons to upgrade. Those running third- or fourth-generation Core i7 chips will dsicover a decent upsurge in performance, though.

To learn more on Kaby Lake, including a complete set of Kaby Lake processors for both laptops and desktops, read our Kaby Lake explainer.

So what’s new? At its most elementary, this chip includes a higher base clock speed because of the efficiency gains permitted by the Kaby Lake architecture. Where in fact the 6700K had a base clock speed of 4GHz, the 7700K manages 4.2GHz.

In addition, the utmost Turbo Boost clock speed – which dictates how fast any given core can go – has been risen to 4.5GHz from 4.2GHz in the old model. That’s a decent jump in performance for a processor which has the same 91W TDP (thermal design power) as its predecessor.

On-board graphics performance has been improved aswell, with Intel HD Graphics 630 replacing the 530 from this past year. As you’ll see from my benchmarks, though, that is no speed demon.

If you’re upgrading your desktop from a sixth-generation Intel Core processor, your present motherboard will be able to accommodate a seventh-gen chip. This will likely need a BIOS update, and that means you should check your motherboard manufacturer’s website to see whether compatible firmware has been released. Asus released Kaby Lake-compatible firmware for our Z170-Deluxe motherboard in December.

If you’re starting afresh, now you can pick from a fresh array of motherboards which includes the Z270 chipset. This new chipset is comparable to the Z170, with extra PCI-E lanes to boost performance on systems with high-performance storage and graphics hardware.

Kaby Lake also supports Intel Optane, that provides a way to increase performance on the cheap. It supports low-capacity, high-performance SSDs to improve the performance of slow devices.

Intel in addition has improved overclocking, both with regards to performance and stability. This will make it far better to push big speed boosts without hanging out obsessing over voltages.

You get the same quad-core architecture with Hyper-Threading, enabling better multi-tasking and performance-heavy tasks such as for example 3D and video rendering.
