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.

Agisoft PhotoScan - Total Time, Overclocked

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 would think since intel seems stuck at a specific design speed for the most part(other than die shrink) that AMD could come up with a better architecture. Maybe there is no better architecture out there? Reply

    ...With the i7-5820K being two generations newer, it should afford a 10-15% performance improvement in CPU limited benchmarks. This is quite amazing if we consider the release price of the i7-3960X was $990 and the release price of the i7-5820K is $389....

    ha, in three years we have 10-15% performance increase.

    Since those parts are nearly identically clocked with a cost per core core being so low you're really getting about a 280% increase in performance per dollar over three years. Compared to other market segments that have practically stalled out everywhere in x86 land yes it is pretty amazing. Reply

    about the gaming benchmarks, core count doesn't really make a difference in most of your chosen games... however there are still a few good CPU-benchmark games that come to mind, Civ V and the Supreme Commander series, to mention a couple. In fact I'd keep an eye out for Planetary Annihilation. It's avalilable this weekend, although I'm pretty sure Uber Entertainment would hand one over just for benchmarking. Reply

    "now the lowest end CPU for the extreme Intel platform". Yep, I'm just using an i7-920, that was exactly at the same spot in its day. Same architecture and memory as the extreme flagship, at a fraction of the cost. Not counting server chips, right?

    Intel Core i7-5820K, you say eh? Hmm... maybe I should write that down for later... Except I'm not planning anything beyond 1080p, then all of these chips and cards are a bit overkill.

    Correction: I want full pedal-to-the-metal at 1080p, perhaps the "average build" should help... right? I appreciate anybody pitching in on the details for a machine to run anything at 1080p (or 1920x1200 actually) at 60 fps, but not more.

    I'd like to add what is the most interesting to me is the 5820k. Hexacore cheap (Intel Hexacore, which IMHO is the only kind that matters). I'll likely never have the budget for a $1000 chip and then the system to do it justice.

    However I currently have an i5-3570 OC to 4GHz. Cost something like $380 for processor and board at the time. For what appears to be around $600 I could now get 50% more cores, hyperthreading and probably be able to reliably OC to a "consevative" 4.2GHz for probably >60% performance improvement for less than half again the cost.

    In comparison to moving up to the i7-4770k, which would only cost maybe $50 or so less, with a modest performance improvement (probably only 15-30%).

    It does make me VERY interested in Broadwell-E and Skylake-E, as those are the most likely points at which I might be looking at an upgrade. I do wonder if Skylake-E will see entry level Enthusiast Octocore, and maybe even if it'll mean high end mainstream Skylake Hexacore.

    That would be an interesting decision if 6 or 8 core processors were not terribly far off in price.

    Dude, did you forget about the cost of having to buy DDR4 memory modules? That will throw your numbers out the window.

    Well, since Broadwell is not out yet, I doubt we'll see SkyLake that soon... Reply
