I don't have the time or tools to measure the consistency of the frame delivery and their latency, so I have to take their results to be true.

Going over the article I can't help but feel they are making a big deal of something that really isn't that big of a deal. I personally don't see much difference on an AMD platform versus Intel in frame delivery when both are GPU bound and doing 55 fps in Crysis 2 per say.

If we take their Batman benchmark and look at AMD low and Intel mid... yes intels have less latency spikes when rendering the frames, however the difference isn't large at all.  Phenom 980 seems to deliver 10-70 ms of latency where the i5 2500k is doing 10-60ms. I don't see that being a large difference at all... It just sounds like something that only the hardcore of the hardcore would notice.



So yeah, I don't agree with their "don't bother putting AMD CPU in to gaming machine" conclusion at all.


Maybe I should have linked to their last page, which does a far better job of illustrating the point than any individual test:

Note how the 3470 outperforms every AMD processor by 25% or more and even the Sandy Bridge i7 at a very reasonable price.

Perhaps frame stuttering doesn't bother you, but personally, it drives me nuts.

Yeah, like I said...I believe them but I am not sure I see the big deal. I had FEAR 3 and Crysis 2 running side by side on 2500k and phenom 940, both with GTX 670s and capturing their frame rate. I really don't see any stuttering on the AMD platform which is unnaceptable.

But yeah, if that bothers someone, I see how they would spend the money on the best CPU. Kind of like ranbow effects on DLP projectors...

One thing I'll say about that chart is that AMD pricing is a little wonky. A lot of those AMD chips can be bought for a lot less money. Like a phenom x4 965 should perform very close to 980 and is 99 bucks usually (79 this week at Tiger Direct). Also, these are all CPU bound scenarios. You could have your i7 processor with least amount of latency but you will run in to a GPU latency and bottlenecks, or SLI/crossfire stuttering in very high end rigs and you're back at square 1.
