Thanks, Marco, for your reply ! The two Sweclockers testers, Jonas Thörnqvist and Emil Björklund, state the following in an explanatory video that they felt compelled to add to the summary section of their detailed, multi-page review (2:59 - 3:17 into the video) : «... the drivers report a clock frequency of 1050MHz, GPU-Z reports a clock frequency of 1050MHz (this could, per se, be due to the software's lack of support for the Turbo fuction), but the point is that, no matter how much one looks at the card, it always runs at 1050MHz ...»

In any event, thanks for an excellent review !...

Marco, when this card was tested by the Sweclockers team (http://www.sweclockers.com/recension/15564-amd-radeon-hd-7970-gigahertz-edition - in Swedish), the conclusions reached were much the same as those you list in your summary above. However, a couple of additional things were noted - the so-called «PowerTune Technology» didn't really work as expected ; instead of the card being tested (much the same line up as in your HH test) running at the basic 1000 MHz speed and being «dynamically» boosted to 1050MHz when required, throughout the whole test the card ran consistently at 1050 MHz, save for a dip to around 1020MHz for perhaps a tenth of a second on a single occasion. Moreover, available software does not permit card voltage to be increased over the standard 1.2V (which itself is a minor increase over the standard 1.175V of the standard 7970), which, of course, limits the card's overclocking potential. Thus, according to the Sweclockers reviewers, the HD 7970 GHz amounts to a factory overclocked HD 7970, in which the engine clock has been boosted to 1050MHz from 925MHz, the memory clock to 6GHz from 5.5GHz, and voltage, as noted above, to 1.2V from 1.175V. An owner of a HD 7970 card should therefore be able to attain the same performance levels as the HD 7970 GHz card by means of a relative modest overclocking of his or her card. In other words, the HD 7970 GHz card, while it does take the speed crown from the GeForce GTX 680 (on most applications), doesn't represent anything new....

Love to hear your comments on the above !...
