CPU Performance, Short Form
For our motherboard reviews, we use our short form testing method. These tests usually focus on if a motherboard is using MultiCore Turbo (the feature used to have maximum turbo on at all times, giving a frequency advantage), or if there are slight gains to be had from tweaking the firmware. We leave the BIOS settings at default and memory at JEDEC (DDR4-2133 C15) for these tests, making it very easy to see which motherboards have MCT enabled by default.
Video Conversion – Handbrake v0.9.9: link
Handbrake is a media conversion tool that was initially designed to help DVD ISOs and Video CDs into more common video formats. For HandBrake, we take two videos (a 2h20 640x266 DVD rip and a 10min double UHD 3840x4320 animation short) and convert them to x264 format in an MP4 container. Results are given in terms of the frames per second processed, and HandBrake uses as many threads as possible.
Compression – 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.
Point Calculations – 3D Movement Algorithm Test: link
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. For a brief explanation of the platform agnostic coding behind this benchmark, see my forum post here.
Rendering – POV-Ray 3.7: link
The Persistence of Vision Ray Tracer, or POV-Ray, is a freeware package for as the name suggests, ray tracing. It is a pure renderer, rather than modeling software, but the latest beta version contains a handy benchmark for stressing all processing threads on a platform. We have been using this test in motherboard reviews to test memory stability at various CPU speeds to good effect – if it passes the test, the IMC in the CPU is stable for a given CPU speed. As a CPU test, it runs for approximately 2-3 minutes on high end platforms.
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.

First! Great Article Ian..I really wish Intel hadn't decided to stop the Mobo work around's allowing i3 overclocking..ImSpartacus - Friday, March 18, 2016 - link
Yeah, fantastic article. I loved how he ran benchmarks at various overclocks.edlee - Friday, March 18, 2016 - link
This was really a shame that this article was not testing a regular i3 with a normal tdp, it would have shown a definate overclock to 4.5ghz and beating stock i5 by a good margin.It would become the celeron 300a of this generation

Yeah, is there a section that explains why a 6100 wasn't used?I admittedly still haven't read the whole article, I found the part that states that a 6100te is a very unusual oem-only part.

Hardly the 300a was a guaranteed 50% oc affecting both cpu, FSB and memory on a socket giving a clean & supported widely deployed set of frequencies, without any drawbacks. It meant a relatively cheap Celeron could compete with top of the line PII's using slower cache memory on Slot riser cards.The skylake BCLK oc, seems to come withdrawbacks slow downs have shown up in some benchmarks, probably due to the complexity of multiple timing domains in modern chips.

The awesome thing with the 300A was the 128KB of full speed cache. I beleive the PII's had double the cache but at half the speed. I loved the 300A - possibly my favorite processor of all time because of when I got it, etc. I had a friend who did the hack to go dual socket 300A's. I remember this whole problem of wanting to run 98SE, but only the NT kernel supported multiple CPU's/sockets/cores (all the same back then...memories).Anyone remember the Voodoo 1/2 add-in cards? Those things were pretty sweet for what they did for 3D games, despite the funny VGA passthru cable...

Voodoo 2 and the 300A. The good old days.I didn't get to play with the 300A, but I got the Celeron 500 and 533, they'd hit 700+ if done right. I got to play with dozens of them and find a good one. It was fun overclocking a Dell.

The point is that CPUs get thermally limitted, increasing volts can increase Watts in a very small area. Therefore there's some sense in trying out a power efficient chip, which has headroom.What the benchmarks really seem to show, is to do well on multi-threaded you need.. 4+ cores. In single thread the cheap Pentium and this i3, do well against the more expensive stock chips.

Interesting article, although it is a little bit skewed to compare the stock performance of that i5 6600 vs the overclocked i3 without including overclocked numbers for the i5, which you could have gotten using the same motherboard you tested the i3 on.Ian Cutress - Thursday, March 17, 2016 - link
That might be in a future piece. Depending on how open base clock overclocking is going to be, at this point I'm wondering if each Skylake CPU I get in should have the overclock treatment given how so few motherboards enable it.
