Overclocked Results

As part of our reviews here at AnandTech we have recently been including a section on overclocked results, because in the end a +10% overclock does not always mean an extra +10% on performance. For our overclocking escapades mentioned earlier in the review, while we were able to achieve 4.6 GHz on the Core i7-5960X, the sweet spot was around 4.3 GHz at a very comfortable temperature. This leads to a +43% overclock over the base frequency, similar to what we saw with Sandy Bridge-E overclocking.

For our overclocking tests, we are using the same graphs as in the last two pages, but adding the data from our overclocked Sandy Bridge-E, Ivy Bridge-E, Haswell and Haswell-E CPUs as well, tested fresh for this review on our latest benchmark suite.

In the past overclocking was all about getting the same or better performance for a lower cost, however with Ivy Bridge-E due to its lower frequency, it was a battle to keep on par with Sandy Bridge-E. Now that Haswell-E has the same frequency deficit (200 MHz) but a +8% increase in IPC, it begs the question if Sandy Bridge-E users with good 4.8 GHz+ CPUs should consider upgrading (for anything other than more cores and an upgraded chipset).

SYSmark 2014

SYSmark 2014 - Overall, Overclocked

SYSmark sees the biggest uplift in its media and office benchmark suites when overclocked, although the financial suite does enjoy the more cores to put the 5960X ahead.

HandBrake v0.9.9 2x4K, Overclocked

Interestingly the overclocked 5960X does aid low quality conversion, showing that with enough frequency all the cores can be constantly fed with data. The 5960X takes the top two spots for 4K conversion.

Photoscan also enjoys overclocking in combination with the cores, but the 3960X overclocked will beat the 5960X at stock despite the extra cores of the 5960X.

Dolphin Benchmark: link

Dolphin Emulation Benchmark, Overclocked

Dolphin prefers single threaded speed, so the Haswell CPUs at 4.7 GHz win here. Haswell does well in Dolphin's emulation overall, hence why the older extreme processors, even when overclocked, are further down.

WinRAR 5.0.1: link

WinRAR 5.01, 2867 files, 1.52 GB, Overclocked

More top spots for the 5960X, with the two extra cores at stock beating the other extreme processors.

FastStone Image Viewer 4.9

FastStone Image Viewer 4.9, Overclocked

When overclocked to 4.3 GHz, the 5960X would seem to produce a similar experience in FastStone to the 4790K at stock. This makes sense as the 4790K at stock is 4.4 GHz in turbo mode.

Gaming Benchmarks

F1 2013

F1 2013 SLI, Average FPS, Overclocked


The overclocked 5960X scores a few points in minimum frame rates, giving another +20% while in SLI.

Bioshock Infinite

Bioshock Infinite SLI, Average FPS, Overclocked


Bioshock average frame rates seem to get a small boost when overclocked, but minimum frame rates are more responsive to the 84W and 88W parts. The variation might be more indicative of the benchmark as a whole, as it only takes one errant slow frame to produce a low result in the minimum FPS results.

    You can't use the 5820K with an X79 motherboard. Reply

    Yip,same here.I7 4790 @ 8.8 GHz.I am still good Reply

    Tell us about your system and setup please Reply

    Yep 2500k @ 4.8 Ghz. Not really Just found it funny that each new post beat the previous by 100Mhz Reply
  • Stas - Friday, April 10, 2015 - link

    Agreed, doing quite well with 2500k @ 4.8Ghz Reply

    I don't mean to be a prick, but you're not going to see anything in gaming performance even if intel releases a 32core 200$ 3.0 ghz processor. Because in the end, it's about the developers usage of the processors, and not many game developers want to ostracize the entry level market by making CPU heavy games. Now, when Star Citizen launches, there'll be a bit of a rush for 'better' but not 'best' cpus, and that appears to be virtually the only example worth bringing up in the next forseeable 3years of gaming (atleast so far in the public eye..) All you can do is boost up single core performance to a certain point before there's just no more benefits, upgrading your cpu for gaming is like upgrading your plumbing for pissing. Yeah it still goes through and could see marginal benefits, but you know damn well pissin' ain't shit ;D Reply

    Not prick-like at all, I appreciate the comment. I'm an old dude who hasn't "gamed" for years and I'm just now getting back into it, trying to figure out what will work and for what price. Your insight is very helpful! Sounds like a lot of guys are using OC'ed i5 cores, good to know. Reply

    Crank up World of Tanks video settings to maximum and watch your FPS sink like a rock. A high end system is needed to run this title at max settings, that only recently began to use 2 CPU cores and 2 GPUs. No one using a mid-range Intel CPU and upper-midrange single GPU will see 60fps with the video cranked to maximum. Reply

    That game is just horribly coded. There is no excuse for the amount of CPU and GPU it needs. Reply

    Check out my post above regarding MS-FSX.

    And, yes, I have installed Star Citizen some time ago [alpha release FINALLY allowed some play], and my system has done well with it, even in alpha.
