Still no word on HD 6790 unlockability

Written by Slobodan Simic

Might not be a simple BIOS flash
There was some talk and rumors regarding HD 6790 unlockability in the weeks prior to the launch, but now, when the card is launched and reviews are out there is still no confirmation that the HD 6790 can be unlocked.

The story is quite simple as the HD 6790 is based on the same Barts GPU as its HD 6800 series brethren, it simply makes sense that these card could be unlocked. Some partners based their own design on the HD 6870 PCB, thus giving the HD 6790 two PCI-Express 6-pin power connectors and HD 6790 is also a decent overclocker as it can pretty easily reach the 1GHz clock for the GPU. Of course, we are talking about overclocking potential of the non-reference cards and not the AMD reference design.

The other side of the story is that AMD might have implemented more serious measures in order to keep the HD 6790 below the HD 6800 series, so it wouldn't interfere with the sales of the latter. AMD definitely learned a thing or two from the HD 6950 launch as during that time the unlockability of the HD 6950 to HD 6970 was almost 100 percent (and might still be) and it simply made no sense to go for the HD 6970, at least for those that were familiar with simple BIOS flashing.

We are still waiting for even some hint of HD 6790 unlockability as this would make this card really interesting and not just another US $150 mid-range card.

It could be unlockable. AMD's yields on these Islands chips are so high that it's likely all the SPU's are present and correct.

Contrast this to Nshittia, who can barely put out a card with all their cores enabled. Utter shit.

I'm pretty sure that they are unlockable although the success rate might not be as high as on the HD 6950... But still waiting for the confirmation... Unless AMD made sure that they aren't as there is always that possibility ...

Wtf...

6790 = Barts LE
6870 = Barts XT
5770 = Juniper XT
5870 = Cypress XT

Both the 6790 and the 6870 have the same Barts GPU, unlike the 5770 and the 5870.

I got so many vote downs but i still think there is no chance that 6790 will be unlocked to 6850/6870 we will see...
