AMD Cayman info (or rumor)

I guess you are mistaken in assuming that with the 250W mode enabled, it automatically ups the clocks; whereas SKYMTL has said that it merely ups the TDP limit (that didn't exist until this point, anyway) and allows for more overclocking.

No, I don't say it automatically ups the clocks, it has a default clock and the tdp limit is there to make sure it doesn't go over it (the TDP), hence the redline at 800 MHz, while at default TDP the card will fluctuate between 650 and 800 (more 650 than 800) to maintain the lower TDP and thus limit performance.

If the card redlines at 800MHZ and 220W, you won't get extra performance at 250W, only if you OC.
