AMD dont throttle anything down with Powertune, even on 6990 .... Powertune and the turbo boost are absolutely not the same and not aimed at the same thing .... In one case it is here for limit the TDP if needed, the other one is here for overclocking the card when it think it is possible or needed.
On the other hand, it will be needed to see how this boost work in details for gaming, instead of just benchmark: If the card is able to OC to 1100mhz under a 2 min phase bench, is it the same when you are playing ? or do just play at 1006mhz ? Will you see the same fps or is it just boosting benchmark score ? what happend when your card is going high in temps after 1hour of gaming ?
The reported graph for TDP show a strange thing, each 3Dmark GT test start high.. ( max...) and go down as the test is going, if you compare with framerate and the load given on the test ( each test start at a low level of charge increasing as it goes to the end, easy to check with fps, as you start high, and end with low fps ), here the tdp decrease from 50W from the start of the bench and the end ( during the test )... does the bench start with 1100mhz? and go back to 1006 then ?... is the difference is really of 50W? if you compare with the 7970 curve, the curve increae in each test, the nvidia decrease in each test.
IF the Turbo boost was based on TDP you should see it going to his max limit and trying to stay there, not decreasing it. ( it will not be a flatline, but it will not look like this )
Indeed this is a nice feature, but im not sure the impact is yet exactly what we want it is. Same goes for suround ? can we compare 3 monitors running at full speed ? and 2 at half speed and the main at full speed ?
( what this? we are not able to use 3 monitors on one card at full speed, so we use 2 at half and 1 ? )
( You are testing the card, so you can try a little test: increase the vcore and let stock clock, then run 3Dmark 11, read the increase in TDP and check the difference.. )
