Intel-Wafer

Today, Intel announced its upcoming Kaby Lake hardware refresh. This launch is the showtime iteration of Intel's new Procedure – Compages – Optimization strategy (dubbed PAO) that replaced Tick-Tock earlier this twelvemonth. It's a modify driven by the realities of lithography. As die shrinks have become more difficult, it now takes longer to move from ane node to the next. This difficulty is somewhat exacerbated for Intel considering it continues to perform total node shrinks rather than relying on hybrid proccess nodes similar TSMC and Samsung.

Intel-Kaby-Lake2

Kaby Lake is built on what Intel is calling "14nm+" rather than its original 14nm. While the company isn't revealing specifics on its design changes at this point in time, information technology has stated that its 14nm+ offers an improved fin contour, improved transistor strain, and a larger pitch. In semiconductors, pitch is defined every bit the center-to-center altitude between ii features. Historically, manufacturers wanted a smaller pitch, non a larger 1 — only packing chips into tighter and tighter spaces increases power density, which ultimately harms performance at this stage. Intel is challenge that these improvements can yield up to a 12% performance improvement and allows for higher clock speeds in the same power envelopes.

Anandtech has details on the specific SKUs, and the top-rated frequencies at the various ability windows have all increased substantially. Intel'due south Cadre i7-7Y75 has a iii.6GHz burst frequency compared to 3.1GHz for the Skylake-derived m7-6Y75. 15W chips are also seeing a large frequency leap, from a similar 3.1GHz summit frequency for the i7-6500U to 3.5GHz for the Core i7-7500U. The overall TDP is higher because the CPU's base of operations frequency jumps — the iv.5W parts all accept base of operations frequencies of 1GHz – one.3GHz, while the 15W fries are in the 2.5GHz – 2.7GHz range. This should ensure that users see at least some small benefits in all cases, but the difference between a 15W chip at 2.5GHz and a 15W chip at 2.7GHz is pretty tiny. Because manufacturers have the choice to build chips that target a variety of clock speeds and cooling arrangements, how much time any organization spends at its heave frequency will depend on the particulars of the cooler. We saw this create somewhat erratic performance with systems based on the first Intel Core One thousand, and that problem doesn't seem to have been eradicated.

Improved multimedia processing

Kaby Lake's larger gains are in the realm of video and multimedia processing. Dissimilar Skylake, which couldn't support H.265 / HEVC Main10 decoding fully in GPU hardware, Kaby Lake can — and Intel is claiming a huge operation increase and subsequent power consumption boost besides. VP9 8-bit and 10-bit decode and encode are also supported in hardware.

Media-Engine

QuickSync and AVC encode as well become a boost in this update, which should provide overall improved functionality — but how many people really use these codecs or settings on a daily basis? It's non a trivial question — the majority of online video is still encoded in H.264, and while information technology'south bang-up to see Intel beingness proactive and adopting these technologies, it's not going to make much of a divergence for owners asking whether or not they should purchase hardware to encounter a meaningful update at present. Then again, Anandtech is reporting that 4K Netflix support, when it somewhen comes to PCs, may only be available to Kaby Lake owners. Skylake customers may be out of luck due to a lack of support for the DRM that Netflix evidently requires.

Faster Speed Shifting

Equally CPUs have evolved, the conditions for "winning" the race have changed as well. The ability to movement between turbo and non-turbo clocks and in and out of slumber states has turned 0W into the new 1GHz — past which I mean that the ability to enter and exit low power states has a critical touch on on battery life and arrangement operation. With Skylake, Intel introduced Speed Shift — an option that immune the CPU to handle its own ability land shifting rather than relying on the operating system.

With Kaby Lake, Intel is introducing Speed Shift 2 and improving its ability to transition between power states.

Intel-Kaby-Lake3

Seventh generation Kaby Lake processors tin boost to maximum frequency much more than quickly and cutting their frequencies when they striking turbo limits. In theory this should make systems faster and more responsive. Overall, Intel is predicting that Kaby Lake volition heave operation by x-19% over Skylake. Presumably most of this boost will be in mobile, where power limits and TDP are critically important. Desktop hardware isn't expected until later this year.
