Office Performance

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.

All of our benchmark results can also be found in our benchmark engine, Bench.

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.

WinRAR 5.0.1: link

Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30 second 720p videos.

The single module of the 7400K shows the deficit in a slightly threaded workload.

Image Manipulation – FastStone Image Viewer 4.9: link

Similarly to WinRAR, the FastStone test us updated to the latest version. 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 thus single threaded performance is often the winner.

For a purely single threaded test, both of the AMD APUs performed similarly here.

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 well known tests with Chrome 35 as a consistent browser.

Professional Performance: Windows

We have a few benchmarks to characterise professional level performance on Windows.

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.

Cinebench R15

Cinebench is a benchmark based around Cinema 4D, and is fairly well known among enthusiasts for stressing the CPU for a provided workload. Results are given as a score, where higher is better.

Linux Performance

Built around several freely available benchmarks for Linux, Linux-Bench is a project spearheaded by Patrick at ServeTheHome to streamline about a dozen of these tests in a single neat package run via a set of three commands using an Ubuntu 11.04 LiveCD. These tests include fluid dynamics used by NASA, ray-tracing, OpenSSL, molecular modeling, and a scalable data structure server for web deployments. We run Linux-Bench and have chosen to report a select few of the tests that rely on CPU and DRAM speed.

C-Ray: link

C-Ray is a simple ray-tracing program that focuses almost exclusively on processor performance rather than DRAM access. The test in Linux-Bench renders a heavy complex scene offering a large scalable scenario.

NAMD, Scalable Molecular Dynamics: link

Developed by the Theoretical and Computational Biophysics Group at the University of Illinois at Urbana-Champaign, NAMD is a set of parallel molecular dynamics codes for extreme parallelization up to and beyond 200,000 cores. The reference paper detailing NAMD has over 4000 citations, and our testing runs a small simulation where the calculation steps per unit time is the output vector.

NPB, Fluid Dynamics: link

Aside from LINPACK, there are many other ways to benchmark supercomputers in terms of how effective they are for various types of mathematical processes. The NAS Parallel Benchmarks (NPB) are a set of small programs originally designed for NASA to test their supercomputers in terms of fluid dynamics simulations, useful for airflow reactions and design.

    AMD's marketing department are a bunch of jerks. The A10-
    7700K has the iGPU from the A8 line! That's going s screw up a lot of people who don't know what they're buying. AMD could really benefit from clearer branding. Trying to be more obscure than Intel is not a good plan. This is the equivalent of Intel launching a new i5 chip with only 2 cores or an i7 without hyperthreading. The one thing that made buying the A10 worthwhile was that iGPU.

    Based on the pricing and performance difference they could easily just have one of each category A10, A8, A6 and Athlon and not lose anything. AMD's marketing idiots are not their only problem but you can't beat the market leader if you under perform them at every step. Clearer marketing would be a real help.

    AMD and marketing go together like oil and water. They have always been hopelessly inept at it. Reply

    *raises hand*

    I was that guy.

    I built my brother a mostly TF2 box to upgrade his ancient athlon desktop this past christmas, and I picked up an A10-7700k for him thinking it had the same igpu as the rest of the A10 line, not the A8 line. :/

    Not your fault. Just blame those AMD guys.
    If you ever met with AMD employees, ask him whether he knows or if he is in charge on naming the product. Punch the guy who gave this atrocious naming

    I always look at specs before I purchase something. Especially since, the part numbers are nearly useless by themselves. I don't care if it's AMD, Nvidia, Intel, Asus, G.Skill, or anyone else. If you get roped in by a product number, your geek card is suspended for a few months. :-P Reply

    Could be worse. I bought an A8 3870 APU. Then bought a motherboard without video output.

    I'm amazeballs, I am.

    Still, for what I do, paired up with an R280 (was 7770) it's fine. I'm waiting for the Zen cores to come out before considering an upgrade, we'll see how they compare to whatever Intel is pushing at that point in terms of price/performance.

    If you upgrade to Windows 10 then your build will be pretty dam good. In fact it will be a far better gaming rig than ANY Intel i3, i5 or i7. Reply

    They paid him the same amount they are going to charge him for a Windows 10 upgrade. He was also probably mentioning it because that chip will benefit greatly in the future from low-level APIs such as DX12. Good troll, I mean try, though. Reply

    In so far as budget gaming is concerned AMD is not under-performing at all. The 860k(and 870k no doubt) is a far more intelligent choice than the similarly priced G3258. It's a shame this test was done the day before Godavari's launch. For those of us not red/green colorblind a review of the 7870k and 870k with their larger stock cpu coolers and improved IPC would have been very welcome. Reply
