Radeon HD 6970 has 250W PowerTune Maximum Power

Written by Fuad Abazovic


Typical gaming 190W, 20W idle
PowerTune Maximum Power is something that we’ve mentioned yesterday and disclosed that AMD claims less than 300W TDP for its high end Cayman part.

Things are a bit better as the PowerTune Maximum Power is claimed to sit at acceptable 250W. AMD also tells its partners and press that the typical gaming power is expected to be 190W while the typical idle power is a quite nice 20W.

The big issue is how do you define and compare Power Tune maximum power with something that we are familiar with, eg. TDP, but we will have some answers after we test the power of these cards in our own environment.

Cypress XT, Radeon HD 5870 had 188W TDP and 27W in idle, which means that the load got much worse, but idle consumption is better. The funny part is that the new chip has 1536 shader, some 64 fewer than the Radeon HD 5870, which has 1600. We suspect that some things got disabled at Cayman for the sake of better yields.

320 5D in Cypress, 384 4D in Cayman, some 20% more

At least AMD is using real TDP watts unlike nvidia's "funky" watts. I'm confident that new Radeons consume less than GTX580.

Yeah and the performance will obviously be much better. They are called "tradeoffs"

As for the specs, you are comparing two completely different architectures! Why?

Nice unbiased neutral article you typed there Fuad, I also love how you added that last sentence and told us all what YOU suspect.

I mean, we totally care about what you suspect rigth?

Shill or not, this is his website. If you want pretty AMD love, go to Semiaccurate. It is interesting that AMD has chosen to hinge their power ratings on something called Power Tune. Why not use what we are all are used to, TDP? We will find out when the cards are released. So my guess is that Power Tune is a big marketing tool being used to pull a haze over what the actual TDP is.

It is starting to hurt, Fuad!!

So much bullshit!

6970 is a complete redesign. 4D shaders instead of 5D.

NOTHING HAS BEEN DISABLED!

Quoting korben43:

well TDP is the maximum amount of power that the coolers need to be able to dissipate (hence the name Thermal Design Point).
its the maximum amount of power the card will every use.

but if in typical usage the card uses much less (and 60watts less is quit a difference), it makes sense to mention that as well.

Troy now you are talking! if Nvidia manages to release a 520mm2 chip with no parts disabled then why Amd should disable their chips?
