Generational Tests on the i7-6700K: Legacy, Office and Web Benchmarks

Moving on to the generational tests, and similar to our last Broadwell review I want to dedicate a few pages to specifically looking at how stock speed processors perform as Intel has released each generation. For this each CPU is left at stock, DRAM set to DDR3-1600 (or DDR4-2133 for Skylake in DDR4 mode) and we run the full line of CPU tests at our disposal.


Some users will notice that in our benchmark database Bench, we keep data on the CPUs we’ve tested back over a decade and the benchmarks we were running back then. For a few of these benchmarks, such as Cinebench R10, we do actually run these on the new CPUs as well, although for the sake of brevity and relevance we tend not to put this data in the review. Well here are a few of those numbers too.

Cinebench R10 - Single Threaded Benchmark

Cinebench R10 - Multi-Threaded Benchmark

x264 HD Benchmark - 1st pass - v3.03

x264 HD Benchmark - 2nd pass - v3.03

7-zip Benchmark

Even with the older tests that might not include any new instruction sets, the Skylake CPUs sit on top of the stack.

Office Performance

The dynamics of CPU Turbo modes, both Intel and AMD, can cause concern during environments with a variable threaded workload. There is also an added issue of the motherboard remaining consistent, depending on how the motherboard manufacturer wants to add in their own boosting technologies over the ones that Intel would prefer they used. In order to remain consistent, we implement an OS-level unique high performance mode on all the CPUs we test which should override any motherboard manufacturer performance mode.

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 totalling 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.

    as my last greatest laptop was back in like 2007.. I had bad laptops ever since and when skylake had huge power saving options I decided to get an Alienware 17 R3 with 4k IGZO screen and 980m Reply

    Looking forward to read up :) Gonna be an awsome review - as always!

    In the section "Skylake's Launch Chipset: Z170":

    "In the previous Z97 chipset, there are a total of 18 Flex-IO ports that can flip between PCIe lanes, USB 3.0 ports or SATA 6 Gbps ports. For Z97, this moves up to 26 and can be used in a variety of configurations"

    Was that last Z97 meant to be Z170?

    Also, thank you for another quality review

    "Was that last Z97 meant to be Z170?"

    Indeed it was. Thank you for pointing it out.

    Man I have been waiting for this! Pumped about DDR4. Reply
  • freaqiedude - Wednesday, August 5, 2015 - link

    why? it basically has no performance impact whatsoever...
    and the powerbenefits are negligable, and it's more expensive...
    I never understand why people buy premium RAM anymore, it simply has no impact on performance except for very very specialized benchmarking applications.

    This CPU is a total joke.... Why Intel would make us pay over 300 bucks for a CPU and not put in GT4e graphics is a total fail. Reply

    Good integrated graphics are a waste here. Reply
  • richardginn - Wednesday, August 5, 2015 - link

    A full on waste. If you are going to spend 300 bucks plus on a CPU you are going to spend at least 200 bucks on a GPU, BUTTT when you can throw in GT3e graphics in a broadwell i7-5775c CPU you must no bring us the pile of crap that is GT2 graphics for the 6700k CPU. Reply

    not true, i'd gladly pay for the best CPU, but have littler interest in buying a GPU that takes extra space and energy/heat.

    Not everyone who wants CPU performance is a hardcore gamer.
