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.

    I guess I wouldn't call something "mainstream" just because some vendors have leftover stock at non-competitive prices, but I see we have differing definitions of the word. I also wouldn't consider SCSI HDs to be "mainstream" but Newegg does a considerable stock of those as well.

    Don't confuse number of choices with actual popularity.

    Not a budget desktop - you'd be much better of with a cheap intel cpu and a discrete gpu. Then you got a great upgrade path to an i5, and better gpu in the future. As for extra cost of gpu, well you can get a second hand one off ebay cheap, or probably scrounge your game loving friends old one and that would still be faster then the A10.

    Only place these really make sense is a budget laptop, where you can't upgrade anything so need the best balanced solution upfront, but these aren't laptop chips.

    I find that in the games benchmarked the A8-7600 isn't far behind (-2.3%; -5.8%, -8.8% and at most 11%), and sometimes even ahead (+3%) of the A10-7800, at only 2/3 of the cost. Seems to be more of a budget gaming winner, at least in terms of the price/performance ratio.

    Ian great review. One thing Id like to see on CPU reviews the inclusion of a single highend CPU and a minimum baseline CPU. In this review all the hardware was more or less in the same range so it is hard to get perspective relative to the ultra high end and the very low end. Keep it up man!
  • Anonymous Blowhard - Thursday, July 31, 2014 - link

    So can we ACTUALLY buy these low-power APUs now, or is this another paper-launch/vapor-launch?
  • morganf - Thursday, July 31, 2014 - link

    Apparently not. At least, I do not see them on newegg at the moment.

    Is there seriously no power consumption tests? wow. And there's no tests to compare kaveri vs a G3258 + a modest discrete card such as a HD7750. wow why even bother with this review, it tells us nothing. Luckily another side was a bit more competent and their data shows a 34 watt increase at the wall vs an 54W TDP i3. Shocking. All that extra power for less performance. I really want to see the data showing a G3258 + discrete outperforming kaveri in Perf/watt. Imagine the horror of spending billions of dollars to purchase a GPU company and spending and years to integrate its IP only to still be worse than your own discrete gpu combined with your competitor's CPU!

    From other reviews on the web, it looks like the 7800 is good for ~85w under load. Oops. No wonder performance is so close to the 7850k. Of course, maybe we'll get some anandtech numbers using a 1200w "noisy" psu eventually.

    It looks as if there needs to be a simple investigation into the clock speed "sweet spot" for Kaveri. There's been the odd article on SA that shows that the top mobile APU usually performs at 2/3 the speed of the top desktop part albeit for about a third of the TDP, so it's worth proving.

    I did see an article earlier that hinted that the 7800 used a little less power under load at its 65W setting than the earlier 7600... http://hothardware.com/Reviews/AMD-Kaveri-Update-A...

    ...however, it disagrees with this article... http://www.techspot.com/review/856-amd-a10-7800-ka...

    It's almost the same here (7600 wins), but look at the improvement over the previous generations... http://www.guru3d.com/articles-pages/amd-a10-7800-...
