CPU Benchmarks

The dynamics of CPU Turbo modes, with both Intel and AMD, can cause concern during environments with a variable threaded workload. There is also an added issue of the motherboard remaining consistent, depending on how the motherboard manufacturer wants to add in their own boosting technologies over the ones that the CPU manufacturer would prefer they used. In order to remain consistent, we implement an OS-level unique high performance mode on all the CPUs we test which should override any motherboard manufacturer performance mode.

HandBrake v0.9.9: link

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.

HandBrake v0.9.9 2x4K

The variable turbo speeds of the CPUs results in a small difference in low quality conversion, and the high single core frequency of the 4790K wins there. For 4K conversion the problem becomes more parallel and the extra cores of the 5960X push it ahead of the pack. The 5930K and 5820K are both behind the 4960X however.

Agisoft Photoscan – 2D to 3D Image Manipulation: link

Agisoft Photoscan creates 3D models from 2D images, a process which is very computationally expensive. The algorithm is split into four distinct phases, and different phases of the model reconstruction require either fast memory, fast IPC, more cores, or even OpenCL compute devices to hand. Agisoft supplied us with a special version of the software to script the process, where we take 50 images of a stately home and convert it into a medium quality model. This benchmark typically takes around 15-20 minutes on a high end PC on the CPU alone, with GPUs reducing the time.

Photoscan's four separate components rely on different amounts of high frequency vs. many cores: check our Bench database for more detailed results but overall the 5960X comes out on top. That being said, the 5820K is less than 40% of the price and is only 1.2 minutes behind.

Dolphin Benchmark: link

Many emulators are often bound by single thread CPU performance, and general reports tended to suggest that Haswell provided a significant boost to emulator performance. This benchmark runs a Wii program that raytraces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single core task using most aspects of a CPU. Results are given in minutes, where the Wii itself scores 17.53 minutes.

Dolphin Emulation Benchmark

Dolphon loves single core speed and efficiency, meaning the 4790K wins out again. Interestingly the large L3 cache of the 5960X also helps here against the 5820K, despite the 5820K having a higher single thread frequency.

WinRAR 5.0.1: link

WinRAR 5.01, 2867 files, 1.52 GB

WinRAR is a variable thread workload, but more cores still wins out. Interestingly the xx60X CPUs are ahead of the xx30K CPUs followed by the xx20K. After this comes the 4790K, and then the 990X on par, showing how far three generations of Intel CPU have developed.

PCMark8 v2 OpenCL

A new addition to our CPU testing suite is PCMark8 v2, where we test the Work 2.0 and Creative 3.0 suites in OpenCL mode.

PCMark8 v2 Work 2.0 OpenCL with R7 240 DDR3

PCMark8 v2 Creative 3.0 OpenCL with R7 240 DDR3

PCMark v8 relies on a number of factors, and it would seem that frequency is preferred over cache and memory. Interestingly the 4930K beat the 4960X in the Creative Suite with no obvious explanation.

Hybrid x265: link

Hybrid is a new benchmark, where we take a 4K 1500 frame video and convert it into an x265 format without audio. Results are given in frames per second.

Hybrid x265, 4K Video

Converting 4K video gets another step in the preference for more cores in Hybrid x265. The 5820K matches the 3960X, showing the progression of CPU generational development.

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.

FastStone is a purely single threaded exercise, showing here how the lower core CPUs with high turbo perfom best, and by quite a margin.

    Gaming was the first area I wanted to look at, so seeing all the comments and review messages saying this is a skip for gaming is great, actually. It means prices will probably drop soon for the gaming parts, hopefully. Reply

    Well there is a LOT more to computing than gaming so this is exciting for a lot of us. Reply

    Not at all, if you're into computing then you'll more than likely buy Xeon anyway. Reply
  • gilles3000 - Friday, August 29, 2014 - link

    Not really, xeons can't be overclocked, even the new 6C 5820K will give you a lot more bang for your buck. Xeons are great for Professional or Enterprise solutions(And are very expensive because of that). But if you need 6-8C and no ECC ram, I'd take a Haswell-E I7 over a Haswell-EP Xeon anyday. Reply

    ECC RAM is pretty nice though, even on a prosumer PC. Reply

    I agree, most xeons are too expensive for all but the most multithreaded jobs. Reply

    actually we overclock Xeon's all the time... see Supermicro Hyperspeed. we OC all the E5-2600v2 we use - 2650v2, 2670v2 and 2690v2. Reply

    One could put together a HEDT system with OC headroom, tons of RAM, and a fancy GPU for the price of an entry level xeon processor, let alone full on server. Xeons aren't for people, they're for companies. HEDT are for prosumers and I think I'm right in saying a lot of people reading anandtech fall into that category. Reply

    Exactly. This is the platform for professional computing home stuff. Reply

    Unless you require ECC memory and-or the ability to install two processors on one motherboard, the Xeon processors are a waste of money. You can also do a modest overclock on the i7 Extreme edition and get some really good performance compared to an 8 core Xeon that costs probably twice as much and can not be overclocked.

    And if you're getting ECC memory that you don't really need, it costs a lot more too. The money you save on the i7 Extreme over the Xeon can also be put towards extra big and or fast solid state storage. The people who do need ECC ram or dual processors tend to know it and they are not even looking at these i7's anyway. There are a lot of things that a lot of power users do that do not need or benefit from ECC ram. That's who these processors are marketed to.
