AMD to Give RV770 a Refresh, G200b Counterattack Planned

[Carfax]

You misunderstood them, they isn't what they were saying at all.
What they were saying is that G200 overclocked still performs better than RV770 overclocked, like it should. They are not saying that G200 scales better with clocks than RV770. G200 has what, a ~15-25% performance advantage on average, so it will still have a performance advantage when both are overclocked.

I'm not claiming the article is stating that the G200 scales better than the RV770.

All I was saying, is that it contradicts a widely held view by ATI fans that the RV770 scales better than the G200 in terms of performance gleaned from clockspeed increases, allowing it to compete with an overclocked G200 even with an inferior overclock, which simply isn't true when you look at the data.

Both the G200 and the RV770 scale similarly in performance when you increase the clockspeed, but because the G200 has more headroom, you can get more out of it.
