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.

I began reading Anandtech long before I actually had a PC, let alone began overclocking.What was that Celeron everyone raved about back in the day? Celeron 200A or something?
I remember Anand used to make reference to it. These overclockable i3s remind me of that. A budget chip that could blow away the higher-performing (and costing) chips of the day when overclocked.
Simpler times... :)

So Why Do We Not See an Overclockable i3 CPU? No competition from AMD.Macpoedel - Saturday, March 19, 2016 - link
Zo SuperMicro seeded you a slow Core i3 that you only got as vast as a regular Core i3. Basically what you showed Here is that a regular Core i3 6100 isn't !much slower than a regular Core i5 6500 but it is over $50 cheaper. Could it have hurt to mention that a Core IE 6100 runs at 3,7GHz?Couldn't you just get the Core i3 6100 yourself or is Anandtech not allowed to buy hardware? I get that you can't just go out and buy a Core i7 5960x or a GTX Titan X, but the company couldn't pay a $100 CPU? Funds can't be that tight. The only conclusion I can make is that you have some deal to only use seeded parts.
Honestly what is the point of this 15 page article if you don't get the relevant parts? Are you yourself satisfied about these results? I think you've done a lot of work completely in vain. It's good that you try to be a little more than just another promotion channel for Intel/SuperMicro/etc but you should have been a little more critical to yourself when reviewing the results and considering the parts you're using.

Oops some words got autocorrected to Dutch in the first paragraph, but I guess it's clear what I'm saying, can't edit apparently.stardude82 - Saturday, March 19, 2016 - link
I don't see the value here when you are spending such a premium for a budget board. Just looking at Newegg, there is only a $10 savings going from an i3-6100 with this board to an i5-6500 with a H110 board.lagittaja - Monday, March 21, 2016 - link
What a pointless article. A 15 page long article which is completely pointless.Are you yourself satisfied with your article Ian?
What did this tell us consumers?
That if you take an unobtanium slow arse i3 and OC it, it performs about the same as the regular i3's which are widely available?
Great scott! I did not expect that! Mind blown!
Now run along to the store and grab a 6100/6300/6320 and do proper testing. We want to see that 4.5-5Ghz i3 go head to head against the OC'd i5..

I'd like to say that part about BIOS obviously isn't true, as people have tried and succeeded to revert back to older versions. Example:"Assuming you can get your hands on the OC BIOS it is possible to flash back to the previous version to regain the base clock overclocking ability. Again the microcode isn’t written to the CPU and is kept at the BIOS level so rolling back isn’t a problem.
To confirm this, I updated my Z170 Extreme7+ motherboard to version 2.60 and sure enough the overclock no longer worked. After rolling back to version 2.16 the ability to overclock my non-K processors returned."

Free lunch is: Abit BH6 + 300A, nForce 2 + unlocked Athlon XP, P35 + <$200 ConroeNot free lunch: Anything today thanks to incredibly restrictive CPU/chipsets lockdowns. With my 4790K already stock at 4.2GHz I'm not going to bother with OC. I'm not even going to mention the absurdity of pairing $100+ mobo just to hack-OC a $100 already at 3.7GHz CPU that would probably get locked down by Intel with a stealth microcode update.

Great read! Definitely gives a very clear explanation of why Intel has denied us a K SKUed i3. I was very excited when I first heard of being able to OC non K SKUed Skylake chips. I have an extra GB Z170XP-SLI mobo & was planning on getting an i3 6XXX to have a little fun with. Now I have to look into it further as I don't want to buy an i3 & not be able to OC it.It's a shame that Intel pulled the rug out from under this so quickly but I from a business point of view you really can't blame them. I got hopes that other ways around Intel's micro code update will be seen though. I heard ASrock released a mobo aimed squarely at getting around the new restrictions.

Sheeeit! That's the best damn AnandTech article in a long, long time. God bless you, Ian! Fantastic. Quintessential AnandTech! I'm thirsty for more.Maybe a super in-depth article on the effects of faster RAM on modern games? DDR4@3200 seems essential for a new build nowadays, and a DDR3@2133/2400 upgrade could potentially be a great upgrade for gamers stuck on 1333/1600. 16GB a must for Windows 10 gaming? Maybe an article on GPU overclocking, AMD GPUs driver overhead, achieving minimum frame-rates, etc.
