Benchmark Results: OpenCL

AMD Trinity On The Desktop: A10, A8, And A6 Get Benchmarked!
By

Alright. We know that Piledriver represents a respectable improvement over Bulldozer, lending Trinity competitive performance versus its previous-generation Llano-based APUs. And we now know that the more efficient VLIW4 architecture, coupled with higher clock rates, translates into anywhere from 15 to 30%-higher frame rates in a number of mainstream games.

But AMD is trumpeting this message of heterogeneous computing—exploiting processing resources, wherever they may be, to maximize performance. We’ve been working on a series of stories with AMD to quantify the effects of open standards like DirectCompute and OpenCL in different software environments, but it remains a challenge to benchmark some of the applications currently being optimized to exploit the hardware AMD is developing.

We’ve really done video transcoding to death. Although we haven’t yet circled back to cover the quality implications of Intel’s second-gen Quick Sync implementation, Nvidia’s NVEnc, or AMD’s VCE, we know that Ivy Bridge’s fixed-function logic is some of the fastest we’ve tested. Moreover, we still haven’t seen VCE enabled in an optimized application (though UVD3 and VCE are fixed-function components of Trinity).

Short of titles like MediaConverter and MediaEspresso, we’ve been at a loss for incorporating productivity-oriented software into our benchmark suite. That’s starting to change more quickly, as companies like Adobe tie OpenCL support into their offerings. Perhaps the biggest win thus far for AMD is Corel’s WinZip 16.5. I mentioned a few pages ago that Corel is deliberately locking out Intel and Nvidia, and I don’t particularly approve of that. However, the compression utility is still immensely popular, making it a great example of how graphics hardware can be applied to a workload not previously associated with graphics.

I have FX-8150 in there so you can see how long it takes the eight-core chip to finish a workload that’s now supposedly optimized for parallelized hardware.

As you can see, though, enabling OpenCL acceleration has a huge impact on performance. What once took 2:11 on the A10-5800K only takes 1:28 when the APU’s Devastator graphics core contributes to the effort. That’s a 32.8% improvement, and likely what AMD is hoping to see across the board as software developers begin figuring out how much of their code can be sped up using graphics resources.

LuxMark, which centers on the SmallLuxGPU2 rendering engine, is another OpenCL-based measurement tool we’ve been using.

In it, we see an A10-5800K trailing a discrete GeForce GTS 450 graphics card in an FX-8150-based machine.

Remember, Trinity employs AMD’s VLIW4 architecture, not GCN, which bolsters compute performance substantially. As such, it’s not surprising to see the Llano-based A8-3850 outrun the A8-5600K with fewer shaders. The next-gen APU family, Kaveri, will employ GCN, though.

We also had plans to run Musemage 1.9—introduced to us in William Van Winkle’s most recent exploration of GPU-accelerated image editing apps. However, the software’s licensing scheme is such that, after three hardware changes, it is revoked. Paraken Technology, the company responsible for Musemage, sent up a handful of licenses to use, but I didn't have time to get everything set back up again. We do plan to test Musemage going forward, though.

    This is so exciting! AMD is probably going to dominate the lower-end and give the poor gamers like me more bang-for-buck as their IGP get better and better :) !

    Well, where are the Ivy/Sandy i5's and i3's???

    Once they are pitted against each other, that will be A TRUE measure of the APU Trinity's marketability

    depending on how its priced, its a really nice alternative for bare budget gaming that opens up a quad core as well

    JiggerByteSo this means that a 'Crossfired' Trinity APU would beat ANY similarly-priced Intel (CPU+discrete GPU) ???Well at least in gaming


    really the question is what gpus are able to hybrid crossfire with it. the information was never public. not all amd gpus will hybrid crossfire with it.

    in the OpenCL Winzip benchmark, when openCL is enabled the workload is done only by the iGPU or the CPU as well ?

    i mean what is the processor usage during the benchmark ? are all CPU cores used? or only one?

    Good question--I'll take a look for you.

    This is awesome. Glad to hear pile driver is making improvements.

    It was public... It will crossfire with up to the 7670, which is a rebranded 6670 from what i know, but with some slight improvements.

    Next stop is to overclock and bench the a10-5800k with some nice 1866-2100 memory. Also some dual gpu action with these apu's.

    Intel fanboy here but I'd really hope AMD catches up this time, coz once they fail, it'll be all over for us consumers, we can't afford Intel to dictate their ultra-ridiculous pricing scheme yet again, in these tough economic times, fewer and fewer people can afford a 200-dollar CPU, so, PLEASE AMD, don't fail us again

    Thats what I was wondering... every time you get an intel cpu review they always throw in an amd or two for comparison. Why didnt they do that here? Cant make an informed purchase if you compare 3 versions of the same car make and model when there are other makes and models out there to look at.

    Oh and Jill... amd only has 10% of the market even with the APU's out there. So if they fail intel only goes from 89-99% of the market... dont see them changing their pricing plans over that.

    Dual Graphics is actually in there ;-)

    Because this is an article of amd's apus. They've already done a comparison between trinity's igp's and intels 4000 series.

    Piledriver is looking good. I'm looking forward to the FX-8350.

    Hope to see these in retail soon, I want to put together a budget box for general web surfing and HD video and I'd love a 65w trinity for it.

    I want to point out an observation. If in floating-point intensive applications, Trinity is negligibly worse than Llano, meaning they're pretty much the same. Doesn't that mean the 2 floating-points units (2 modules) of Piledriver are acting on par with the 4 (4 cores) of Llano?
    Anyone tell me if I'm wrong and why.

    EDIT: Oh wait, they're clocked higher, but not by that much, though it is substantial. I would think it's still a big architectural improvement.

    Also, I've noticed that in multiple articles, the writers are strapped for time. This isn't good though it could be understandable. Maybe TH should hire more "hands" or something?
    I'm not sure how we'll find out when that video mentioned of the comparison with the A8-3870K and the i3-2100/2105 would show up. Well, unless we constantly check back.

    Don't worry TH, you haven't lost me as a fan. It's just constructive feedback. I love you guys!

    Don't worry--I'm working on the data right now. As it stood, this story took more than a week of all day/all night testing, troubleshooting, new BIOS installing, and re-testing to nail down. It can go on indefinitely if you let it ;-)
