Intel didn’t just launch the new Core i7-7700K desktop CPU, it made a comprehensive update to its entire product line. The initial Kaby Lake mobile refresh was limited to a handful of SKUs; with this launch Intel is bringing out a larger number of cores intended for every price point. The new chips are, for the most part, drop-in replacements for the Skylake SKUs Intel launched in 2015 and 2016, though most of the models feature at least a small clock jump over and above what Skylake offered.

Kaby Lake is priced nearly identically to Skylake in virtually every case, but the Core i5-7600K has a 3.8GHz base clock and a 4.2GHz turbo clock, whereas the Core i5-6700K was a 3.5GHz – 3.9GHz chip. These gains are preserved through most of the product stack; the 35W Core i5-7400T has a 2.4GHz base, 3GHz turbo, compared with the Core i5-6400T with its 2.2GHz base and 2.8GHz turbo.

There’s a new nomenclature attached to many of Intel’s 15W and 28W CPUs. These new chips feature what Intel is calling “Iris Plus,” meaning they incorporate a 64MB EDRAM chip alongside the GPU core. The 128MB EDRAM cores that Intel has previously shipped with Skylake and Broadwell aren’t being carried over to the Iris Plus line, at least not for now. OEM uptake on these cores has never been high, even though they can improve integrated graphics performance by almost 100%.

All of the new 7th-Generation chips support VP9 hardware decode, as well as supporting H.265 encode/decode completely in hardware. As a result, all of these cores are comparable with streaming 4K video from Netflix or any other service that agrees to use Windows PlayReady DRM via the Edge browser. Intel has already said it won’t bring its EDRAM to any desktop quad-core SKUs this cycle, so if you were hoping for a non-embedded chip with Iris Plus you’ll have to look for a Skylake-based core or consider the Broadwell-based Core i7-5775C, which does have the 128MB cache.
