    Where are the cold hard numbers o back this up? What if the hybrid crossover brings better performance then a more expensive dedicated card alone can? Here's an example where at full HD resolusion it provides a significant improvement compared to the same dedicated card alone: http://www.tomshardware.com/reviews/...0k,3224-4.html. Unfortunalety I couldn't find more in depth benchmarks for hybrid crossfire nor any benchmarks of hybrid crossfire on Linux (if it works at all).

    It's questionable because it's not a realistic scenario, most desktops used for gaming today have displays with at least full HD native resolution while the benchmark was only performed at lower resolutions.

    Turn it to 1920x1200 with medium/max detail and check again. Surprise-surprise, you don't benefit from the stronger CPU now and this is exactly what he's been trying to explain you.
    Hence spending more money on a stronger GPU and buying a cheaper APU is likely better than buying a stronger CPU and a weaker GPU for the same sum.
    Two of the test I mentioned were using 1680x1050. Crysis was set at Mainstream details, Civ V at High Quality. Yet the difference was still there. I wish there were more in-depth tests out there. In the meantime, I'll take cold hard numbers over wishful thinking.

    • You said nobody would crossfire with such a puny CPU.
    • He suggests games were generally gpu bound with the APU, as proven by adding a stronger card (thus making crossfire seem like a sensible approach)
    • You pointed out a system which had a significantly stronger GPU (which costs more than the entire APU) doing questionable benchmarks to prove that not all games on all systems are GPU bound.


    That doesn't even make sense.

    Maybe I wasn't clear enough, when I said "Can you show me the game (or any other graphics intensive application) that is CPU bound on this APU?" I meant when using the APU's GPU. And it should have been obvious, when deciding if upgrading the GPU is worth it or not you need to know what the bottleneck is in the current situation, not any other.

    Of course if you'll use a high-end card at a low resolution with low graphics quality any game will be CPU bound, even on an i7. You proved nothing.

    Mwahahahahahaha!!!
    I apologize. I thought you knew what you were talking about.

    All games perform better with a more powerful CPU; all using the same GPU.
    You're not actually making a strong argument when you're talking about all of the tests using a 5870 instead of the onboard GPU. Sure, if you have a 5870 and are played at interesting resolutions, the 5870 is going to be under utilised. We're not talking about that though, we're talking about how much additional room the CPU or the GPU will have on the APU under normal conditions.

    Stick metro on at native monitor res with a HD7670 in both systems, and then show me the diifference and I'll accept your point. Better yet, allow the APU to use crossfire and if the Intel still wins then you've won the argument.

    They do actually, its just on a totally different page which I guess is good for extra clicks and misleading people who were linked directly to the page.

    Either way though, the fact that bug77 linked that suggests he doesn't actually know what he's talking about, so arguing with him is pointless. I'm out.

    Thanks for reminding everyone there are worse benchmarks then those performed by Michael. Compairing the performance of a high-end GPU at 1024x720 low quality is pure genius. Not to mention they don't even mention what GPU they used.

    Anyway, my point was not that there are no faster CPUs out there. I am also aware there are GPUs out there that are fast enough to be starved by the performance of this CPU (or just about any CPU actualy).

    My point was that for example the E-450 APU in my laptop is completely CPU bound, switching graphics from low quality to high sometimes actualy improves the frame rate as more stuff gets offloaded to the GPU. However, this APU (and probably all A series APUs), even though they are slower then most Intel CPUs, are still fast enough and can actualy benefit from a more powerful GPU.
