![]() Not to jump the gun here, but that's pretty close to where my three samples landed. With Intel increasing clock speeds by 300-400MHz on most models, my hope prior to the launch was that Kaby Lake unlocked processors would routinely hit 5GHz with overclocking. ![]() There's obviously a higher cost with the EDRAM module, but since it functions as both a high-speed cache for graphics and CPU workloads, it's actually somewhat useful-it would be much more useful than the more than one-third of the CPU die that's currently devoted to graphics many users will ignore, for example. (We may see a future T-series part for AIO, though.) That's not too big an omission, considering many desktop users will have a separate graphics card, though I've always found it interesting that Broadwell (i7-5775C) with a decent overclock to 4.2GHz actually comes out ahead of most other CPUs when it comes to raw gaming performance. One thing worth mentioning is that Intel has no plans at present to release any desktop SKUs with Iris Pro or Iris Plus graphics-meaning, there will be no L4 cache/EDRAM desktop models. For single-threaded performance, it will be pretty close to the 7600K and 7700K, though with less 元 cache. Core i3 parts don't include Turbo Boost so they only have a single base clock speed, and in this case the 7350K tips the scales at an impressive 4.2GHz. Finally, the Core i3-7350K is an interesting beast. The i5-7600K is clocked a bit lower, 3.8GHz base and 4.2GHz turbo-and this is the first Core i5 part to ship with stock clocks that can break 4.0GHz. That's officially the highest stock clock Intel has ever released, beating the i7-4790K by 100MHz. The Core i7-7700K sits at the top of that stack, with a base clock of 4.2GHz, 200MHz higher than the Sylake i7-6700K, and the maximum turbo clock is 4.5GHz (300MHz higher than 6700K). What remains is the usual collection of i7/i5/i3 parts-two i7, four i5, and four i3-and in a small break from tradition, Intel will have K-series (unlocked CPU multipliers for overclockers) for all three lines. In fact, I could argue that the last time we saw a true desktop-first architecture from Intel goes back at least to Nehalem/Bloomfield (CPUs like the i7-920 launched November 2008), and even that architecture was really a server design tweaked for desktop 'enthusiasts.' But Core 2 (early 2006) was a desktop-first design at least, and even the desktop parts derived from mobile and server designs can still be interesting.Īll told, there are 16 new desktop processors, though many won't be particularly interesting for our purposes-like the T-series chips that are more likely to be found in all-in-one systems, so that removes six of the CPUs from our radar. If you're reading between the lines, many of the above changes are for laptops and similar devices, while desktop users are a secondary concern. The net result is that at roughly the same power requirements, Intel should be able to tack on a few extra hundred MHz in clock speed. Intel says 14nm+ will actually be less transistor dense than 14nm, with a larger fin pitch and reduced channel strain. Outside of these architectural changes, Kaby Lake appears to be largely the same as Skylake, with one qualification: Intel is tweaking the 14nm process, with a refined fin profile (the FinFET part of the process) they're calling 14nm+. Intel's Kaby Lake uses a new 14nm+ process technology to improve clock speeds.
