Second, math lesson -- percentage increase is difference over original so 6/38 and 135/880. That is 15.7% and 15.3% percentage respectively. Before I just truncated.
Third, you made the claim that 929MHz to 1017MHz doesn't scale well. I provide an exampled that shows it scales fine in another game. If you were only talking about one game then state that clearly. I haven't seen at benches for any game at 1100Mhz so I can't comment on that. If 1000Mhz to 1100MHz scales so badly show some proof of runs at those clocks.
Really all you have done is shown that AMD drivers don't play nice with BC2. That may be true, but you can't say the 6970 won't scale to 1100MHz or that it is only useful in CFX at 1600p or above based on one game review at one review site. As on other games, I can provide arguments to the contrary. Also, people play different games... just because you always play BC2 doesn't mean I do as well.
BC2 was just one of many games showed. Other games had similar performance problems at 5760x1080 as well and when they didn't, they did exactly equal or almost as good as the 570s. BC2 tends to be the standard just as BF3 will be in November. Some people may be more into RTS games and won't care though.
The original post was simply stating that 6970s are more equal to 570s than a 580 as someone else claimed in their post. As far as single card comparisons, the 560 did better than the 6970 in BC2, Metro 2033 and MW2. I showed benchmarks showing equal OC comparisons providing that information. I also said that the 6970 would be a better choice even though the 570 does just as good at 2560x1600 and below because it has more framer buffer to crank the AA up.
- You didn't provide benchmarks of 929 to 1017. You provided a comparison from 880 to 1015. If you actually knew about OCing, you would know that bumping the clock from 1100Mhz down to 1000 wouldn't drop fps by an exact 9% as you're trying to claim it being completely linear all the way.
I already stated that I tested my DCII 570s beyond my current 1020Mhz using up to 1.212V and didn't see much of a performance gain and didn't feel comfortable with the high voltage or heat. There is a point at which further OCing will have severe diminishing returns as any good OCer would know. The Sapphire HD's fps won't scale up to 1100Mhz as well as the MSI Lightning for instance since it can handle more current.
4th - There were other games besides just
BC2 where the 6000s had serious performance issues at 5760x1080. When they didn't, they didn't do any better than the 570s which seems strange due to their extra 720MB of frame buffer.
I'm not claiming that people only play BC2 and that they only
have problems with BC2; I was just pointing out that the 570s are more equal in performance/price than 580s are.Edited by PoopaScoopa - 4/15/11 at 7:55pm
