AMD Radeon HD 6790 is a great overclocker

Written by Slobodan Simic

Might be unlockable as well
Our sources that are currently preparing for AMD HD 6790 launch have confirmed that the card is a great overclocker and that disabled shaders might even be unlockable.

As you already know, the HD 6790 is based on quite well known Barts GPU, the same one behind both cards in the HD 6800 series, and it even uses the PCB that is similar, if not the same, as the one used for the HD 6870 cards. The choice of HD 6870 PCB should explain the maximum value TDP of 150W and even the fact that it needs two 6-pin PCI-Express power connectors.

For now we can only confirm that the upcoming HD 6790 cards will have an insane overclocking potential, and we are hearing that 1GHz is possible and quite easily achievable. Bear in mind that partners will surely go for their own cooling solutions that should make those overclocking ventures even easier, and if the shader unlockability gets confirmed, AMD might have a really good card on shelves once it launch on 5th of April.

We'll keep our ear close to ground to hear if any of our sources manage to confirm the shader unlock rumour.

Unlock could save it from being an other 5830 I guess.

see what i mean...ur speaking the truth and still get negative hits! 5830 was overpowered and underperforming , i thought the very same thing about this card, but wouldn't it most likely unlock to 6850 performance, which only uses 1 six pin?

Theo only way to get positive votes. Is to declare you're undying love towards all things AMD.
And that Nvidia and Intel are the scum of the earth.
Fudzilla is over run with AMD fanboys so any negativity towards AMD will get you a down voted. Best just to ignore the votes they don't do any thing so i don't under stand why there there.

We can pretty much estimate the power and price already. The TDP of a 6870 and performance lower then a 6850 = a bad card IMO, the only thing that can make it look good is a 100€ price tag.

@The blue fox/bardenck

Its pretty much about the time. There are times when NV fanboys overweight AMD ones...guess I just missed it, oh well.

It's pretty obvious that the power consumption is due to the HD 6790 being a salvaged HD 6870 since it uses the same circuit board. That's why it has 2 PEG ports. It is also the reason that it will overclock like crazy. If the price is right, this could be a good card.

Exactly bbo320... most people see the two PEGS and think "OMG! this card must be power hungry".

Another reason I think they are using two pegs is for the segment these cards are addressed to. If the cards are cheap they are to be put in cheap computers hence cheap PSU's that won't really match high-end PSU's usually used in setups that have 6800 or 6900 in them.

Also, I said this in an older article, the power usage comes from active shaders, and as proof there is the 6950 unlocking case which made the card draw as much power as a 6970. Following this logic a lower active shader count equals to a lower power usage.

You're a nvidia fanboy but I completely agree with you on this one. The 5830 was a failure: performance slightly above the 5770 and price slightly below the 5850.

You're a nvidia fanboy
But I have a 5770 @ 930/1330 and even an AMD cpu >.>
