Newcomer AMD Radeon HD 7970 GHz Edition has "new special faking feature". It is own secret "GPU Boost" technic. AMD driver/GPUz reports different frequencies than they really are! GPU clocks of "GHz edition" are 1.0-1,1 GHz (some vendors has 1,05 or 1,075 MHz) AMD gave them a free hand in this. But there is impossible to check real frequencies, AMD keeps it masked by driver. Stay tuned ... we will prove it later. Card is here ... awaiting for detailed testing.

Update 1: Its look like, GPU is working @ 1,2 GHz instead of 1050 MHz reported in driver/GPUz/utilities. Power consumption/heat/noise corresponds to these higher clocks! Stay Tuned ...

Wow so their card is running at 1.2 ghz out of the box :eek:
Happy days :)
Voltage control and water cooling is going to be fun with these cards :D
 
Probably just wanted to keep these boost speeds under wraps until the NDA expires. Gpu-z probably needs to be updated to read the real clocks.
When are the reviews out?
Gibbo, any news?

This

Entirely possible gpuz isn't reading the clocks correctly.

Nice, why would they mask it though?

In the same way as pedandatic posting masking the 'dynamic boost' feature as not being an 'auto overclocking' feature?;):p
:rolleyes:

Hope it does have it, just to settle the boost/overclocking stock out the box performance debate.:)
 
Have you noticed how the chap,seems to conveniently ignore the Nvidia boost feature, and then starts says AMD is faking scores due to implementing its own boost mechanism?? He is a hardware reviewer from the Czech Republic AFAIK.

Moreover,overclocking tests will highlight any hidden boost mechanism anyway and so will comparisons to existing pre-overclocked HD7970 cards,so as usual,it is an invented conspiracy to gain more page hits. On top of this,even the GTX680 clocks were not properly mentioned by drivers and 3rd party utilities before launch either. I would refer you all back to the Kepler thread where cards were supposedly were running at around 700MHZ when people ran utilities on production cards leaked before the launch.

When it came to the actual launch, the appropriate driver set was only really released then and updated utilities did show the proper clockspeeds.

However,as with the Nvidia feature I really do hope it is documented better by reviews,so we can get a good idea of what clockspeeds production cards will get.

You have to be careful with OBR. He really does not like AMD that much and has been banned from forums like XS due to his attitude(not necessarily the information he gets which can be accurate),so he always tries to twist anything with AMD the worst way.

If it's truly at 1.2GHZ it must have little to no OC'ing headroom.
Since it's a "GHZ edition" People going to think it's 1GHZ 7970, it skews the results in favour of a now massively clocked 7970.

EDIT : Can see this totally not being true :p

Whichever way you word it, it isn't an auto overclock.

If AMD are doing something similar then it's the same principle there as well.

It depends - we don't know if the new SKU has more overclocking headroom. Another factor is the way the boost mechanim(if true) functions. Is it like with Intel and AMD Turbo functions,boosting upto a maximum preset clockspeed,or is it like with the system Nvidia is using where the top boost clock is not preset??

And I will still call it for what I and most other random forum users see it as an auto overclock, reviewers don't mind reffering to it as overclocking do they, so why all the fuss?:

'NVIDIA's dynamic overclocking algorithm works well and provides a nice speed boost for the card.'

As techpower up would tell you when they start most of their reviews!;)

If they all boosted to a set speed rather than a minimum set speed, you might then have an argument.

Paint it up whichever way you like it is still overclocking as we know it, they all boost to different speeds, no 2 cards do the same as such.

It's not a dig, time and time again I have stated that it's a fantastic feature.

And I will still refer it the same, maybe it can be put to bed at last as they will both be doing it, then the pedantic posting will cease as it will be back to the faster card instead of stock out the box this dynamic boost that.

Then hopefully we can then go back to talking about enthusiast overclocking again.
