GPU Performance: Between a Radeon HD 6450 & 5570

I grabbed some of our most recent GPU testbed data for the Radeon HD 6450 and the Radeon HD 5570, the latter of which is architecturally most similar to the Sumo GPU in the A8-3850. If you're wondering how much sharing memory bandwidth between the GPU and four CPU cores impacts performance, it's pretty significant. The HD 6450 only has 160 cores compared to 400 on the 6550D, while the 5570 has 400 cores running at 750MHz.

Note that these scores are taken with DDR3-1333, however if we push the memory bus all the way to its limit on desktop (DDR3-1866) you end up with performance that's somewhere between a 6450 and a 5570. AMD's branding makes sense in this case (6550D).

Overall the Radeon HD 6550D in AMD's A8-3850 APU performs a lot like a discrete Radeon HD 6450 card. For a GPU that ships integrated with all high-end A8 APUs, I really can't complain. The real question is how does it stack up when compared directly to Sandy Bridge, which brings us to our next page...

    Well there's a few ways to look at it.
    I've played tons of games at 1024x600 resolution, they can still look pretty good.
    Console games run around that resolution sometimes too, so apparently millions of people are fine with it. It's still way above a DVD resolution.
    It's not much of a change to 1366x768 either.
    IGPs are pretty limited on bandwidth so go get discrete to play at 1920x1200 obviously.
    Just my 2 cents.

    I dont see why you toss consoles or DVD in the mix here. We're not talking huge but low dpi TV screens where resolutions like this are quite normal but screens that are used for computers. A screen with that resolution would be tiny, compared the standard these days - and nobody would accept that unless its a crapbook. Reply

    Keep in mind that these are entry level GPUs here, anything above 1280 x 1024 isn't really going to do too well. Llano at least lets us have a conversation at 1280 x 1024 but for the most part integrated solutions are going to keep you to these types of resolutions. I tried to provide both a reference point to older IGP results (1024 x 768) as well as some perspective for discrete cards (page 3 at 1280 x 1024). As you can see by some of the numbers on page 3, at 1280 x 1024 in many benchmarks we're pretty close to 30 fps already.

    That being said, this is just a preview. If you'd like I'll provide some resolution scaling data in the full review :)

    Take care,
    Anand

    I disagree. There are plenty of cases where the AMD chip is in the 100's. Nobody expects them to run Metro 2033 on high so don't bother using that as an excuse.

    1680 minimum, and medium settings - we'll see who holds on to the fps and who collapses. And for god sake put some decent RAM in the AMD system.

    I have to concur with everyone else, Anand.

    There were a couple of tests where this setup had 80-100 fps.

    I think particular attention ought to be paid to the most popular games in your list, and that's probably Call of Duty Modern Warfare 2 + Black Ops and WoW.

    Given that the Llano is a budget desktop chip, who is going to buy one? The semi casual gamer who is probably interested in the Call of Duty franchise or World of Warcraft.

    And in both of those games this APU gets 100+ fps.

    Most screens these days are widescreen, 1366 x 768, 1280 x 720, 1680 x 1050, and 1920 x 1080. I think these are the resolutions to focus on.

    But I really appreciate the review having just discovered this web site last week it's really nice. Keep up the great work!

    My apologies - I was referencing the data on page 3 which purposefully looks at higher resolution/quality settings. There you're not looking at 100 fps in most situations but more down to earth frame rates.

    I've already begun work on high resolution testing and varying memory bandwidth, our story at the end of the month will focus much more attention on these questions as a result of your feedback :)

    Take care,
    Anand

    This would be a perfect scenario for the list older games that you guys were putting together a few months ago.

    Show us some 2005-2008 action at decent resolutions (1366x/1680x)
