What I think neliz is trying to say is this:

The TDP limit can be adjusted by a slider (+/- certain %)and the card adjusts core clock to keep card within the TDP limit (note: not heat, but TDP). The core clock is also the limit of how high the card will clock. That is, if you set TDP to +20% to 240W, but core clock is maintained at 800 MHz, the card will just stay flat at 800MHz at all times. However, adjust it to 900 MHz, and the card will run at 900MHz as long as it is within the TDP limit of 240W you set.

Example: With higher TDP limit, the core clock can be maintained higher - hence the chart shows that at +10% power, the core clock can be maintained at 800 MHz evenly.

To go above 800, you still have to OC the card - and you can adjust the TDP as well to maintain it if you want.

It feels like... turbo core for GPUs

Interesting stuff! It makes 2 x CaymanXT's feasible for 6990 since you can play around with power...
Yeah, that's what I got from his messages as well.

So an all-default HD6970 is not actually an all-default HD6970, because it goes down from its default clocks at some times.
