CPU Benchmarks

The dynamics of CPU Turbo modes, 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 Intel 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 LQ Film

The latest Intel processors have the lead for low quality Handbrake conversion, and despite the generational gap between the FX-4350 and the A10-7800, the extra MHz is preferred here.

HandBrake v0.9.9 2x4K

For large frame manipulation, the latest architectures mixed with the most threads perform best.

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.

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

Dolphin seems to work best with high single core speed and Haswell.

PCMark8 v2 OpenCL on IGP

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. As this test is new, we have not run it on many AMD systems yet and will do so as soon as we can.

PCMark8 v2 Work 2.0 OpenCL IGP

PCMark8 v2 Creative 3.0 OpenCL IGP

The combination of processor graphics and OpenCL support push the AMD APUs up to the top of our PCMark tests.

Hybrid x265

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.

Cinebench R15

Cinebench R15 - Single Threaded

Cinebench R15 - Multi-Threaded

Cinebench is typically Intel territory for high IPC processors, but when it comes to multithreaded rendering, extra threads help.

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.

3D Particle Movement: Single Threaded

3D Particle Movement: MultiThreaded

All the calculations in 3DPM deal with floating point numbers, a known sink for AMD compute.

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.

Web Benchmarks

On the lower end processors, general usability is a big factor of experience, especially as we move into the HTML5 era of web browsing. For our web benchmarks, we take four well known tests with Chrome 35 as a consistent browser.

    Unfortunately, Ian's been omitting power consumption numbers lately. Wish he weren't :\

    " News from Intel might change that with Broadwell, as back in May an announcement regarding a socketed, overclockable Iris Pro CPU would be coming to market."

    That sentence gave me a migraine :(
  • leopard_jumps - Thursday, July 31, 2014 - link

    price wise is A8 6600K

    Kaveri: Fantastic if you absolutely require IGP gaming. Otherwise, humiliated by a $60 Pentium.

    I'm sure that AMD must have done the research, but I'd be astonished if the intersection of:
    1) Willing to buy non-Intel CPU
    2) Interested in gaming
    3) Unwilling to invest in a dGPU
    Is big enough to be profitable.

    Or perhaps it's just the least-unprofitable niche that AMD feels it can compete in, having largely ceded the server and high-end desktop markets to Intel, in addition to their questionable mobile story.

    I miss the AMD of yore, but buying up ATI seems like a better decision with each increasingly-lackluster CPU release...

    To make matters worse, you can get a G3258 with an Z97 motherboard from Microcenter for $100. (Overclocked mine to 4.3 GHz).
  • meacupla - Thursday, July 31, 2014 - link

    damn, that's a good deal.

    But the average price for PAE and a Z87/97 mobo is around $160~$180.

    See this thread for overclocking on Non-Z motherboards:

  • silverblue - Thursday, July 31, 2014 - link

    I haven't found enough benchmarks to suggest anything about the 7850K vs. the G3258 barring the price differential...

    Having bought a i7-920, pentium 3220, i7-3770k, i7 4770k, I can say CPU speed matters way more than iGPU if you are not gaming.

    General use - internet/email, you may think cpu speed doesn't matter, but it does. You might get your email to open "instantly" instead of waiting 1-2 seconds.

    watching videos - "gpu acceration" with a gtx 670 just irritates me as the pixels are all meshed and audio becomes out of sync when you seek through the video. I just use the cpu.

    creating videos into 264h content - if you use gpu acceleration, no to encoding runs will produce the same result, in the end, you'll want to use the cpu for consistent results, unless you want to do a quick rip to your ipod, in that case just use quick sync, it's very fast.

    file compression/extraction - cpu speed matters here especially compression.

    file copy - cpu speed matters. If you ever run a low end cpu and try to copy at 100MB/s you start using a non-significant portion of your cpu.

    I've never run into a case outside of gaming where even the GMA 900 with the 915G chipset wasn't good enough, and what ever iGPU intel is using now is much better than that. If you are a "light gamer" and play mostly flash or shockwave, i would say intel igpu is still "good enough." If you are doing "budget" build your monitor would probably be on the "budget" side too, and wouldn't be good enough to display your games at high res or without significant ghosting at high frame rates.

    I'm not an intel fan boy or an amd fan boy, I just go with what suits my needs best. In the end, I ALWAYS read what AMD is up to because the one thing I am waiting for is, AMD manages to run all their cpu-floating point operations through their iGPU. THAT would be very interesting. Similar to the FPGA added to the upcoming line of intel XEON processors.

    Intel needs competition. Unfortunately, AMD isn't providing it.
