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.

Legacy

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.

    Zen appears to be matching the $1050 i7-6900K. I would say that is far better then Nehalem. Reply

    Zen needs more than 40% improvement to be competent, but I am hoping as well. Reply

    The word you're looking for is competitive. Reply

    Competent, competitive. AMD is neither at the moment so both of you are correct. Reply
  • prisonerX - Thursday, August 06, 2015 - link

    Actually AMD is very competent given how much money they have to work with. AMD would be much more competitive too now if it were not for Intel's well documented illegal practices against AMD.

    It's like a thief robbed your home and you're praising the fact that it's great that you can go to the pawn shop and buy what he stole from you.

    Wow, blaming years of terrible decisions on Intel... that's a new one. It wasn't Intel that made AMD adopt automated design tools, or ignore the much easier, faster and obvious option of releasing a tweaked 8-core Ph2. AMD has made massive losses year after year. Their debts are awful. Blaming all this on Intel is just nuts. Reply
  • medi03 - Thursday, August 06, 2015 - link

    Yeah. Blaming Intel that HP didn't want to use FASTER AMD CPUs FOR FREE, fearing Intel's illegal revenge is just nuts.

    AMD Athlon 64's beat Intel in all regards, they were faster, cheaper and less power hungry. Yet Intel was selling several times more Prescotts,

    Not being able to profit even in a situation when you have superior product (despite much modest R&D budget), yeah, why blame intel.

    In the Athlon 64 days, yes, AMD had a better product but the cold hard truth behind the curtain was that AMD didn't have the manufacturing capacity to supply everyone that Intel was feeding chips to. Reply
