The Intel 6th Gen Skylake Review: Core i7-6700K and i5-6600K Tested

For the last segment of graphs, we have the same data as the previous few generational pages but we have also included other processors from our database for non-standard comparisons.
All of our benchmark results can also be found in our benchmark engine, Bench.
Office Performance
Dolphin Benchmark: link
Many emulators are often bound by single thread CPU performance, and general reports tended to suggest that Haswell provided a significant boost to emulator performance. This benchmark runs a Wii program that raytraces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single core task using most aspects of a CPU. Results are given in minutes, where the Wii itself scores 17.53 minutes.
WinRAR 5.0.1: link
Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30 second 720p videos.
3D Particle Movement
3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores.
FastStone Image Viewer 4.9
FastStone is the program I use to perform quick or bulk actions on images, such as resizing, adjusting for color and cropping. In our test we take a series of 170 images in various sizes and formats and convert them all into 640x480 .gif files, maintaining the aspect ratio. FastStone does not use multithreading for this test, and results are given in seconds.
Web Benchmarks
On the lower end processors, general usability is a big factor of experience, especially as we move into the HTML5 era of web browsing. For our web benchmarks, we take four well known tests with Chrome 35 as a consistent browser.

With 0 competition at the high end, its not really a surprise.Refuge - Wednesday, August 5, 2015 - link

Yeah, sad. Single digit generational IPC improvements and a trickle up of clockspeed - not exactly exciting times in the CPU world. But I'm kind of happy, in a way, as who wants to have to upgrade their whole system rather than just the GPU every 2 years. It strikes me that Intel are doing a pissload of work for very little results though.wallysb01 - Wednesday, August 5, 2015 - link
What’s lost is that these gains are coming with roughly zero increased power draw. Much of the gains of years past were largely due to being able to increase the power consumption without melting things. Today, we’ve picked all the low hanging fruit in that regard. There is just no point in being disappointed in 5-10% increases in performance, as time moves on its only going to get worse.There is also no point in getting mad at AMD for not providing competition to push intel or at Intel for not pushing themselves enough. If added performance was easy to come by we’d see Intel/AMD or some random start up do it. The market is huge and if Intel could suddenly double performance (or cut power draw in half with the same performance) they would do it. They want you to replace your old Intel machine with a new one just as much as they want to make sure your new computer is Intel rather than AMD.

And yet, one would expect much lower operating voltage and/or much higher base clocks with a new architecture on a 14nm process, as compared to the 22nm Haswell. The relatively tiny improvements in everything except iGPU speaks to either misplaced design priorities (i.e. incompetence) or ongoing problems with the 14nm process...Achaios - Wednesday, August 5, 2015 - link
Very often. You are simply NOT a gamer. There are games that depend almost completely on CPU single threaded performance: World of Warcraft, Total War series games, Starcraft II, etc.Nagorak - Wednesday, August 5, 2015 - link
The games you listed aren't ones where I'd think having hundreds of FPS would be necessary.jeffkibuule - Thursday, August 6, 2015 - link
FPS can vary wildly because so many units end up on screen.vdek - Thursday, August 6, 2015 - link
I'm a gamer, I plan a ton of SCII, my Xeon 5650 6 core @ 4.2 ghz does just fine on any of those mentioned games. Why should I upgrade?Kjella - Wednesday, August 5, 2015 - link
Yeah. I upgraded from the i7-860 to the i7-4790K, the only two benchmarks they have in common in Bench suggests that's roughly a 100% upgrade. And a lot of that is the huge boost to base clock on the 4790 vs the 4770, I prefer running things at stock speed since in my experience all computers are a bit unstable and I'd rather not wonder if it's my overclocking..
At this rate it looks like any Sandy Bridge or newer is basically "use it until it breaks", at 5-10% increase/generation there's no point in upgrading for raw performance. 16GB sticks only matter if you want more than 4x8GB RAM. PCIe 3.0 seems plenty fast enough. And while there's a few faster connectors, that's accessories. The biggest change is the SSD and there you can always add an Intel 750 PCIe card instead for state of the art 4x PCIe 3.0 NVME drive. Makes more sense than replacing the system.
