Can OpenGL And OpenCL Overhaul Your Photo Editing Experience?

Benchmark Results: Photoshop CS6

Finally, the crown jewel of our benchmark apps: Photoshop CS6.

Again, with no hardware-based support, Intel’s Core i5 puts in a remarkably fine showing, losing out only to our FX/Radeon HD 7970 configuration. But with GPU-based OpenGL enabled, we see performance increase by roughly 200% to 500%. Surprisingly, our A8/APU config turns in the best GPU-accelerated time, and we did not see the same sort of scaling expected when we moved to testing on the Radeon HD 7970.

Not unexpectedly, CMYK takes 10% to 20% longer to process than RGB, but otherwise, the response patterns are almost identical. Adobe’s first swing with OpenCL in Photoshop exhibits very clear scaling across our platforms. From the “low” of our mobile A8 APU to the best-of-breed FX/Radeon HD 7970, we see over a 2x gap, which, in our opinion, speaks fairly highly of the APU’s capabilities. When you can get 50% of the performance of a top-end card essentially for free, that’s a good deal. The desktop A8 APU lands smack between these two, making an even more persuasive case for budget buyers with plans to use this application.

When we step up the blur load to 300, we see CMYK suddenly finishing much faster—go figure. Nevertheless, the scaling pattern remains similar, although we’re now approaching a 200% difference between low- and high-end with GPU-accelerated OpenCL enabled. Moreover, check out how much more benefit GPU acceleration delivers across the board compared to running in software with the workload increase to 300—up to a 15x benefit in our A8/Radeon HD 7970 configuration.

    Now Adobe uses both CUDA and OpenCL that's superb.

    Tahiti is pretty darned fast for compute, especially for the price of the 7900 cards, and if too many applications get proper OpenCL support, then Nvidia might be left behind for a lot of professional GPGPU work if they don't offer similar performance at a similar price point or some other incentive.

    With the 7970 meeting or beating much of the far more expensive Quadro line, Nvidia will have to step up. Maybe a GK114 or a cut-down GK110 will be put into use to counter 7900. I've already seen several forum threads talking about the 7970 being incredible in Maya and some other programs, but since I'm not a GPGPU compute expert, I guess I'm not in the best position to consider this topic on a very advanced level. Would anyone care to comment (or correct me if I made a mistake) about this?

    How many CPUs would it take to match the tested GPUs?

    That would depend on the CPU.

    Would be interesting to compare the i7 ivybridge against trinity in openCL

    can you test like these combos:
    core i5 + 7970
    core i5 hd4000
    trinity + 7970
    trinity apu
    core i7 + 7970
    and core i7 hd 4000, and compare against fx8150 (or piledriver) + 7970.
    it seemed to me as if the apu bottlenecks the 7970 and the 7970 could work better with an intel i5/i7 cpu on the graphical processing workloads.

    Nvidia cards test please. People needs to know if it's better/faster to go OpenCL or CUDA.

    no intel or nvidia because for professional editing you need hardware capable of more than gaming...

    2687W: 2P server CPU, 8 core (16 threads), 3.1 GHz (3.8 GHz turbo), and 20 MB of L3 cache.

    Cost per CPU: $1885

    Quadro, Tesla... These are graphics cards that are also capable of more than gaming, even if like alpha said above, many of them aren't always the very fastest such cards for compute performance anymore and most definitely aren't the fastest compute cards for the money.

    I'll have a look and see if I can find benchmarks to compare with those done in this article.

    I'm hoping that OpenCL will make it possible to implement high demanding video codecs for smartphone GPU's.

    This would allow software vendors to implement their video format of choice everywhere while making it able to play fluently everywhere where it matters!

    And being able to play video's fluently on computers with weak CPU's.

    What semi-modern computer has a CPU so weak that it can't play video? Even a single core Atom CPU can play video without trouble. I'd be more worried about old GPUs (such as older Atom netbook GPUs and other weak GPUs) not always being able to play modern video very well, not CPUs. Heck, even my almost ten year old laptop with an old P4 is GPU limited in video, not CPU limited.

    Prior to the HD3k, Intel wasn't able to play videos decently; only blocky and badly rendered pictures of something moving on the screen. Period.

    And no, unless the Atoms are on the ION platform, they can't play any video in more than SD format. Let alone apply filters for re-size.

    And to directly answer your question. Core2 Duos on laptops were not able to play videos decently and nothing before that was able to, where any iGPU from nVidia or AMD was able to prior to the C2D's in notebooks. I'm pretty sure in desktop was not that much different.

    Cheers!

    My GMA 950 IGP of my 2GHz Pentium-Dual Core computer (on-board IGP) from 2007 or so would disagree with you. It handles 720p excellently and 1080p well and even my Pentium 4 630 from my 2004 desktop can handle 1080p excellently once I gave it a Radeon 5450. It's CPU is only a 3GHz P4. My old Dell 2.4GHz P4 laptop with an Intel IGP (I'd have to check to make sure which one it is) can't handle 720p very well, but the CPU has not trouble with it, just the GPU. Heck, my Atom netbook (1.6GHz single core from around two years ago, I'd have to check the model to be sure of it's GPU and CPU model number) can play 480p just fine and 720p/1080p also don't tax the CPU much, just the GPU.

    My whole point is that weak CPUs have no trouble with video, only weak GPUs have trouble with video. You'd have to find an extremely slow CPU to be unable to watch video on it so long as the rest of the computer, such as the graphics, are good enough. Even low-end GPUs like my GMA 950 can handle video playback decently, so having a GPU should not be much of a problem except with extremely weak systems such as some Intel netbooks or a very old notebook/desktop without a decent video card.

    Maybe so, howerver, nVidia is supporting openCL with 301.42 drivers. IMHO, having nVidia cards benchmarked would be of interest to those of us who own nVidia cards.

    that's why there are more CUDA apps out there....you are very wrong my friend....CUDA is and will be the better engine
