HD 6900's Here!

ok thining about this switch methodically.
it wouldn't be a switch for what outputs to use, because surely that would be on the output panel.

its position would indicate something to do with the crossfire fingers.

its not going to be for power regulation because didn't they say that the tdp adjustment(overclocking) would be from the control panel (drivers

having a switch that turns of portions of the core, stupid idea, considering how complicated these gpus are is there really going to be a cheap little click switch to turn bits on or off.

no I'm sticking with it being something to do with crossfire.

maybe it allow you to pair up like cards in one position or unlike cards in the other, like a 6970 and a 6950. but then that would be stupid as they would just have it enabled all the time.

no idea we will have to wait and see.

The problem is that it shouldn't be something which software can handle and it's not something you will use daily as someone else has said so possibly a reset switch for when overclocking or bias flashing goes wrong.
 
i remember seeing the 1gb 5870 doing better than a 2gb 5870 at normal and lower resolutions, could the switch be to choose between 1gb or 2gb depending what resoultion ur running?

Oh, that switch. Red-Blue LED on the backplate.

These are quite large another 4cm and they wouldn't fit in a HAF 932 and it's pretty large. Will more than likely be having to remove my HDD cage for the 6990

Oh and NDA ends in 3 days not long to wait

it's just a switch:D think everyone should calm down lol
 
I thought someone had already said it was for bios/firmware flashing of one kind or another. Same way a lot of ssd's have the exact same kind of switch but most production models the switch is hidden behind casing. Pre-production models often have a few switches for either debug modes or to make bios/firmware flashing easier, or other reasons aswell.

information is too silly at the moment, I think AMD made a mistake with not letting someone unofficially leak some reliable info from somewhere we pretty much trust, raised expectations are only bad if your product isn't fast though.

I did say a LONG time ago that 35% would be pretty decent for same process and that AMD has two options really on the same process, bigger, lower yields, uber performance, expensive, similar size and a bit of a performance boost, or same size/marginally smaller, similar performance way cheaper.

Lets be honest, that was the 6870, if they make something 50% bigger than the 6870, with 15-25% more performance I'll be frankly, shocked, and appauled, and may have to sell my AMD stock(literally, it might go down :p ).

But I can't see it, if the 6970 was too new, and the 6870 brought with it efficiency increase Cayman can't match, why make Cayman at all, just bring out a 6970 that is 2x 6870 and thats it, all done, save money, it would be out already and it would beat anything Nvidia can release. I just can't see them doing that, if the 6870 was THAT close to the 6970 that, at 50% bigger would cost circa 60-65% more to produce(255mm2 WILL have higher yields than a 380+mm2 card, thats just how it works), it would be canceled by now.

Theres a slim chance a lot of the missing performance is in something as simple as driver that doesn't know the 4 basic shaders can get together and do stuff the 5th shader normally does. But come on, seriously, what are the chances that a 50% bigger core is less than 30% faster? I'll give you a hint, none.

Then theres one last thing, maybe AMD screwed up, maybe they went with a new metal layer or transistor type from TSMC and its just not working for them, maybe simplified core logic was supposed to enable a higher clock speed and it didn't work out, but AMD haven't really made a big process mistake in quite some time, even 2900xt is astonishing as its a 65nm product backported to 80nm in 6 months and well, worked, thats impressive, it was also fairly decent clocks and beat the 8800 in things like Bioshock in dx10.
