We know at least a handful of details: DDR4 memory support, 14nm process technology, modest IPC gains and impressive GPU improvements. But the details have remained a mystery on how the "tock" of Skylake on the 14nm process technology will differ from Broadwell and Haswell. That changes today with the official release of the "K" SKUs of Skylake — the unlocked, enthusiast class parts for DIY PC builders. PC Perspective has a full review of the Core i7-6700K with benchmarks as well as discrete GPU and gaming testing that shows Skylake is an impressive part. IPC gains on Skylake over Haswell are modest but noticeable, and IGP performance is as much as 50% higher than Devil's Canyon. Based on that discrete GPU testing, all those users still on Nehalem and Sandy Bridge might finally have a reason to upgrade to Skylake.

The system bus design has also been upgraded this time; we are now on the third revision of DMI with a bump in performance to 8.0 GT/s, which is equivalent to x4 lanes of PCI Express 3.0. This upgrade in bandwidth turns out to be incredibly useful for platform builders like ASUS that can take advantages of up to 20 lanes of PCIe 3.0 on the Z170 chipset itself! That means new storage options, configurations and more expandability for the non-E level of processors from Intel.

The integrated graphics on Skylake are drastically improved though the details on how they are doing it are still a mystery until we get to IDF. Our IGP test shows nearly 50% performance improvements for the Intel HD Graphics 530 compared to the HD Graphics 4600 on Haswell. As it turns out, Broadwell and the Core i7-5775C with its Iris Pro graphics and eDRAM implementation are still going to blow the Core i7-6700K out of the water, but more on that later.

Intel’s early issues with 14nm yields have been well documented and we won’t go into them here, but 14nm is a more expensive process with an increased number of lithography steps as we reach the limits of current semiconductor technology. FinFET was introduced back in 22nm, but to move down to 10nm makes either the current process more expensive or other methods have to be used. As a result, we see Moore’s Law stretching out from an 18-24 month cadence to a 24-30 month cadence for the first time in fifty years. As we’ve seen with the graphics card market recently stalling at 28nm, there is a need (or at least opportunity) to develop more power efficient architectures rather than just relying on die shrinks to do it for you.

I've never seen the CPU market this stagnated. Thanks AMD. If Intel had some real competition, we wouldn't be seeing these 7-10% performance increases year after year. This is frankly ridiculous.




I love how they left out the 5th Gen cores...
