The Intel Skylake i7-6700K Overclocking Performance Mini-Test to 4.8 GHz

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.
Synthetic – 7-Zip 9.2: link
As an open source compression tool, 7-Zip is a popular tool for making sets of files easier to handle and transfer. The software offers up its own benchmark, to which we report the result.
Conclusions on Office Benchmarks
Similar to the professional tests, the gains here are in-line with what we would expect with +200 MHz overclocks.

Why would it make a difference? The BCLK is now decoupled from anything that would matter... It's just another tool like the ratio, one that could let you eke out an extra 50MHz or whatever if you really care to take it to the edge.Khato - Friday, August 28, 2015 - link
Two inquiries regarding future Skylake testing:1. While the initial review was intriguing in terms of actually exploring the DDR3L vs DDR4 2133 performance difference, higher DDR4 frequency testing is still absent. Will there be a memory scaling article at some point?
2. What's the point of evening including the discrete gaming benchmarks? Is there a plan to revamp this category of testing to provide meaningful data - inclusion of minimum frame rates, exploring different settings, using different games.

Yeah, it would be nice if we could get some proper frame time benchmarking.varg14 - Saturday, September 5, 2015 - link
I too would love to see High end DDR3L compared to DDR4 on skylake and if the tight timings of DDR3l are beneficial in what areas if at all.ImSpartacus - Friday, August 28, 2015 - link
I feel ridiculously shallow for asking this but could we see fewer tables that look straight out of excel going forward?Anandtech has a glassy table & graph design language. While it might be a bunch of excel templates, it still lets me suspend my disbelief a little bit more.
I can't justify my request with any tangible argument other than something "feels" off. I apologize as I understand how frustrating such feedback can be. I trust Anandtech to always be improving & setting the standard on all fronts.

They've used the same format a number of times before and it's pretty damn clear and easy to understand. Prettifying the excel tables on a mini article is a waste of time.ImSpartacus - Saturday, August 29, 2015 - link
You're right, this isn't an isolated issue. I didn't comment on it first time or the second time.And it's hard to tell someone who exhaustively tested numerous scenarios that they oughta spend even more time to ensure that they follow style guides and that the extra time spent won't even affect the utilitarian value of the results.

Nice overview.But isn't overclocking in reality not really relevant anymore? A remnant of days gone by?
Dont get me wrong, I was an eager overclocker myself back in the day. But back then, you could make a 2-300$ part perform like a CPU that cost twice as much, if not more.
Today, processors have gotten so fast, that even the cheap 200$ CPUs are "fast enough" for most tasks.
And when you do overclock a 4ghz CPU by 600mhz or more, is the 5-10% speed increase really worth it? Most people would have been better off taking the hundreds of dollars they invested in coolers, OC friendly motherboards, etc and put them towards a better CPU instead.

There's a lot of people that just do it for fun, same way people mess with their cars for often negligible gains... Not all spend a lot on it either, I'd buy the same $130-170 mobo whether I was OC'ing or not, and I'd run the same $65 cooler for the sake of noise levels (vs something like a $30 212).
