AMD Dual Graphics Analysis: Better Benchmarks; Same Experience?

Results: Company Of Heroes 2

Even at its lowest detail settings, Company of Heroes 2 brutalizes our hardware at 1920x1080. A lower resolution would likely help, but these configurations simply don't deliver a smooth experience as-tested. Technically, Dual Graphics does show a slight advantage over one card or APU on its own. But with minimum frame rates under 20, the results are hardly exciting.  

Charting frame rate over time shows us that the low minimums we saw in the first chart aren't symptomatic of a one-time dip. Performance actually falls under 30 FPS for a significant portion of the benchmark run.

The frame time variance in Company of Heroes 2 is extremely high. But the frame rates are so low that this probably isn't important. Performance falls below what we consider playable, so there's not much point in comparing the stutter-ridden output in video.

    Hmm, IDK, I feel like there is definitely a performance boost in certain games that are just bordering on playability. That said, if you want really good graphics, why not buy the Athlon with disabled GPU cores? Same goes for the intel P series. Just add a discrete card.

    "That's just not right."

    If I had just paid good money for a new graphics card for Dual Graphics, I'd be feeling pretty well cheated out of my money right now.

    The drivers tested in this analysis are a tiny bit too old, just before the Crossfire Frame Pacing fix was released.

    Could we see this performed again with Catalyst 13.8?

    See page 2:

    "You'll notice that we're using the Catalyst 13.6 Beta 2 driver instead of Catalyst 13.8 Beta, which adds a frame pacing feature for smoother, more consistent output. AMD tells us that the new driver does not affect Dual Graphics configurations. It only works with multiple discrete GPUs. Rest assured that the configuration we're presenting is as up to date as possible."

    Despite the bad news, I think this article was just what a lot of people needed. It helps clears up a lot of confusion and hearsay about AMD Dual Graphics options, like the being able to enable the Radeon HD 7750, or if GDDR5 makes any difference or not. More importantly, it shows how important software optimization is for product performance, and hopefully AMD strives to eliminate similar issues in the future.

    As this issue unfolds, I hope there are as informative follow-ups to accompany them. Good job!

    Ah - my apologies.. Thanks for the response.

    Well, now I see that my Llano box I built for a media center 2 years ago will be completely rebuilt rather than getting an add in card. If AMD's next gen APU will use the FM2+ boards as well I may go that route. If not, I'll probably wind up dumping AMD all together and go with an Intel rig.

    thanks for the clarification

    Can frame pacing be forced?

  • If only AMD spent more of their time and their resources on software optimization rather than on those competition-bashing ads. Seeing some silly ads or reading about some flip/flopping (I now get paid by a different overlord) salesman, bashing Intel or nVidia products, does not instill the confidence in buying AMD products, specifically their APUs and (professional) GPUs. I really do want to buy your stuff AMD; less marketing more software development...pleeease.
