| Unfortunately there's no way for me to unlink the stream processors from the rest of the graphics core, so I can't test that, but you're right in the sense that it does help the graphics core OC'ing results that were shown. I didn't mention that, but at the same time I still think you'd see the memory scale better when OC'ed if it truly were bottlenecked.
Perhaps "bottleneck" is the wrong word here. When I hear the word bottleneck, I think of something that's blatantly holding the architecture back from performing to its max potential. Right now, the evidence suggests that the graphics driver is bottlenecking RV870's performance potential more so than its 256-bit memory interface in my opinion. Sure, integrating a 512-bit memory interface may net RV870 a little more performance, but I still think they made the right call here.
Believe me, I was questioning ATI about this quite a bit at first, but now after seeing all the benchmarks I'm a believer. ATI's Dave Nalasco and Baumann made it quite clear that it was an either/or scenario. We weren't going to get 1600 shaders+512-bit memory interface with RV870 and still have a semi-affordable GPU. Something had to give and they decided it was going to be the mem interface. I discussed this in the original 5870 article last week. Flag this | Edit this post |

| Believe me, it's tough picking which resolutions/settings to test. Especially when you mix in such a wide variety of cards as I did for this article. That makes it tougher because you don't want to overdo the settings for cards like the 8800 GT, but at the same time you don't want to end up bottlenecking the high-end cards either.
Again, like I said, it's tough.
And I'm still fixing things here and there with the article btw. There's so much stuff I'd started on and wanted to cover, but ran out of time with the NDA expiring at 12AM EDT. Flag this | Edit this post |

| | Yes, you can run audio over HDMI with the 4890, and any other recent ATI GPU. I haven't tested it at 1366x768 specifically, but I don't see any reason why the hardware shouldn't be able to scale to that resolution. You may just need to tweak a few settings in CCC. Flag this | Edit this post |

| The graphs were correct, the headers weren't. Again, another cut and paste error on my part, and as a result, this 18 page article has now become a 19-page article.
As you can see, I made a lot of changes/additions to the suite of tests from the last CPU review, and that affected the template I use to make the HTML. I tried to catch everything but I obviously missed the addition of Left 4 Dead and how it affected my previous Crysis graphs. If you spot anything else like this in the article pls let me know, it's been a long labor day weekend for me as you can see. Flag this | Edit this post |

| My guess is the adaptive mode isn't as effective at dynamically adjusting power modes and NVIDIA's offering full power as a new alternative. I'm tempted to run some benches and see if there's any difference.
I don't think they'd provide this feature unless they had a reason. Flag this | Edit this post |

| That's a nice price!
When you get a chance, I'd recommend upgrading from that Intel Smackover mobo. It's BIOS layout is terrible and isn't as powerful as the Taiwanese mobo manufacturers. As I'm sure you know, it's also only got 4 DIMMs. Flag this | Edit this post |
