Compute & Video Transcoding Performance

AMD's hope with Fusion is that the GPU transistors will regularly be used for more than just 3D gaming. Today we're still hunting for good uses for GPU compute, but we do have a few benchmarks that we can use to illustrate Llano's GPU compute prowess.

Our compute benchmark comes from Civilization V, which uses DirectCompute to decompress textures on the fly. Civ V includes a sub-benchmark that exclusively tests the speed of their texture decompression algorithm by repeatedly decompressing the textures required for one of the game’s leader scenes. Note that this is a DX11 benchmark and obviously can't run on Intel's Sandy Bridge GPU.

Compute: Civilization V

The Radeon HD 6550D performs as expected - it offers performance close to the 5570 and above that of the 6450. Memory bandwidth constraints are less of an issue here apparently as the 6550D delivers 89% of the performance of the 5570.

One area where we can compare the Radeon HD 6550D and Intel's HD Graphics 3000 is in video transcoding performance. For that we turn to ArcSoft's MediaConverter 7 and measure performance transcoding a 15Mbps H.264 encoded 1080p Quantum of Solace rip to a 4Mbps 720p iPhone 4 compatible file:

Video Transcoding Comparison
  AMD A8-3850 Intel Core i3-2105
Frames Transcoded per Second 63.7 fps 165.2 fps

While the A8-3850 can exploit its GPU cores for transcoding, Intel's Quick Sync continues to be the faster method of transcoding video as we found in our original Sandy Bridge review.

    What happened to them, I thought it was stated that they will be up "in a few hours". And what about some DX11 tests, seeing Llano is capable, why not run a few DX11 games to see what it can do? Reply

    Would be interesting to see how this A8-3850(150$?) will fair vs an intel pentium G840 + amd 5670(85$+70$=155$). Simply because these are the 2 options one would have when picking up a system with same money yeah?

    Also, wont this system would make so much more sense, if mobo makers came out with a 20$ motherboard w\o pci-e, hell no old school pci slots either. One 4gb ram slot of speeds upto 1866. Hmmm, that will bring AMD into the win for ultra cheap desktops. Or I am just crazy maybe. :p ANyway, always best part about AT is the technical part and the colorful graphs yey,

    Slap this in a windows version of a Mac Mini and you have the coolest HTPC/portable 720p gaming system around. Almost as good as a PS3 or 360, tiny, quiet and versatile. Reply

    To me this just will not due for desktop at all. I can see the positives for notebooks and all but unless there is a greater range to crossfire with this is no use to me. Isn't that the problem with PS3 and 360, you are stuck with the video that the unit comes with at the time of purchase. Yes you could just pop in a better Fusion chip later and keep the rest of the system the same,that is better that what you can do with a PS 3 or 360. I have at least 5 AMD video cards that will smoke this thing.

    I know AMD will improve the Fusion line in the future. but they will never come even with the latest separate CPU and video card. Is Open CL really going to be that big of a deal that you will need the feature. I can't see this APU doing Open CL and gaming at the same time. Would, or do games use Open CL/Direct Compute at the the same time as Direct X. Would they not be using the same GPU at the same time and choke the system down.What about multitasking, you couldn't run a Open CL/Direct Compute at the same times as you were playing a DX game at the same time without killing the GPU Right ?!?

    I just don't see what good except as others have said that this desktop stuff is aimed for OEM's to save money and raise the preformance of their lower end computers. I am open to that i'm totally wrong about how this works.

    The Llano APU in a desktop just makes absolutely no sense as a budget gaming system unless you really only want the APU's graphics. Otherwise, if you are planning to actually buy a cheap discrete GPU you'll already surpass Llano's on-board offering with like a $50 board AND you won't be severely bottlenecked by their piss-poor performing CPU. The mobile Llano's make sense, but the desktop ones are just too damn gimped compared to the i3... the lowest performing Intel processor.

    /yawn wake me up when Bulldozer gets here.

    When you did the price calculation of Llano vs. Athlon you forgot to include MB price.
    Llano MB prices are >100$ today.
    And IMO, Phenom X2+d.GPU is much better option for gaming PC than Athlon X4.

    would crossfire work with a nvidia video card? Reply
