>> Intel Launches 7th Generation Kaby Lake: 15W/28W with Iris, 35-91W Desktop and Mobile Xeon
The death of Intel’s ‘Tick-Tock’ means that Kaby Lake is Intel’s third crack at their 14nm process. 14nm started with Broadwell (5th Gen, tick), introduced a new microarchitecture with Skylake (6th Gen, tock), and now is in the ‘optimization’ stage with Kaby Lake (7th Gen). This means an improved ‘14nm Plus’, offering better power efficiency and higher frequencies through a less strained transistor floorplan. Intel is launching a myriad of SKUs under Kaby Lake, ranging from mobile KBL-U at 15W and 28W through mobile KBL-H at 45W and desktop-class KBL-S at 35W to 91W. This includes three overclocking SKUs for desktop, including an i3 variant. Here’s the front page of AnandTech’s Kaby Lake launch coverage. ... <snip rest: full artticle at link below>+

>> The Intel Core i7-7700K (91W) Review: The New Out-of-the-box Performance Champion
The i7-7700K, launched today, is Intel's fastest ever consumer grade processor. Using Intel’s third set of processors at 14nm, using the new 14+ variant, we get processors with a better frequency / voltage curve that translates into more performance, better efficiency, and the potential to push the silicon further and harder. The i7-7700K is part of Intel's 7th Generation of Core CPUs, which often goes by its internal code name 'Kaby Lake'. The Kaby Lake family, as of today's launch, stretches from 91W on the mainstream desktop down to 4.5W for notebook processors, all using the same underlying technology in different core and integrated graphics configurations. The i7-7700K is the top part of this processor family, featuring four cores with hyperthreading, a 4.2 GHz base frequency, a 4.5 GHz turbo frequency, a couple of new tricks and all for $303 list (so about $330 retail). ... <snip rest: full artticle at link below>

>> The Intel Core i5-7600K (91W) Review: The More Amenable Mainstream Performer
The Core i5-7600K, launched today (January 3, 2017), is the other unlocked processor from Intel’s 7th Generation line of Kaby Lake Processors. Kaby Lake is Intel’s third set of processors at 14nm, using the new 14+ process variant, which aims to give processors with a better frequency / voltage curve that translates into more performance, better efficiency, and the potential to push the silicon further and harder. Here is our review. ... One of the big debates in a lot of online PC performance forums is the Core i5 vs Core i7 debate. On the one hand we have a cheaper processor with four cores, while the other has hyperthreading and costs more. The argument always steers towards whether hyperthreading actually works, whether it is needed, whether the cost justifies it, or if it makes any difference in the workload for that user. ... Ultimately it comes down to this: in most cases, the Core i5 will perform equal or reasonably equal to the Core i7, especially when it comes to gaming. As a result, there’s no need to spend the extra, especially given that the Core i7 typically comes at a large ($50-$100) premium, which could be better spent getting an SSD or a better graphics card. ... <snip rest: full artticle at link below>
