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.

    was waitting for this reviw very badily......

    probabily amd llano desktop version is just a beafed up amd apu mobile version, it has a clear winnig point on its mobile platform ( added advantage of batterylife and graphics performance for relatively lower price than the intel counter part )

    but for desktop its a mixed review....i think the bulldozer family apu..which is the real desktop apu variant must come into picture, for a face to face comparison with the intel counter part ...phew we have to wait another 4-5 months for that i guess.

    a8-3850 would be good for casula gamers....else i3 will provide more performance and lower tdp for others

    Hi Anand,

    -Thank you for the nice review, but would you add image quality (IQ) comparison as well? From what I found around the internet, Intel HD 2000/3000 still lacking competitive/comparable quality of the rendered images. So, it would be better to show what's the actual IQ the user will see even when the frame rate (FPS) looks like it's playable.

    Thanks again.

    Yes, that is coming up in a separate review. Give me a couple of hours. Reply

    -Wow, what a quick reply, thanks!

    -Hmm, Anand said you're covering HTPC scenarios, right? So would that mean video (output) quality only? Or that will include 3D games as well?

    Regards.

    Thanks. very much looking forward to that t, being gaming or video. Reply

    Seconded, a comparison of image quality would be nice. I'd also like to see 1024x768 dropped from testing, who runs that resolution? Looking at a couple of other reviews, the tests were done@ 1680x1050 with good frame rates on Llano. If a game has to be dropped down to 1024 to play then why bother, it's going to look ugly anyway.

    -In my place, budget/value systems often bundle with second-hand 15" or 17" CRT (sometimes LCD too) to reduce the sale price. So, I think 1024x768 (and 1280x1024) resolutions are still relevant. :)

    Regards.

    Hey, you dissin' me? My home rig is 17", my work rig is 2x17", and not gonna change soon. I don't want to. I enjoy life even at sub-HD resolutions too... Reply

    Just kiddin', my laptop is 17" too ... 17" of eye-killing 1920*1200 madness.

    No reason to change, except you can get LED pannels for like 130 euros now .. and damn it's good for the movies.
