yeah that's what I was talking about, I had the feeling ATi have constrained performance on these cards a bit to get much lower power consumption since they'd still be as fast as an 4870X2. This shows how fast these cards can get when you throw away the power consumption factor. Bring on a hot and steamy 5870 I say

Thanks to the author for releasing the voltage/speed claims.

Agree that it is testimonial to 5890. Who knows if it'll use 6gbps GDDR5 (probably), but I wouldn't be surprised to see it use 1.3v, just like 4890. Since they quote 1035mhz, normalizing it, 1.3v/1ghz sounds about right for 5890...at around 215W.

That is, of course, if there isn't another revision of the chip ala rv790...which the rumor mill suggests there will be. It's been mentioned (Czech Gamer) if G300 launches this year, ATi will lower prices to compete. If it launches next year, AMD will respond with a new revision and an according x2 part (5890x2) to battle the corresponding G300/gx2 parts.

Getting back to this, it looks like ASUS is really being quite fair with the voltage options...Both would end up (1.35 on 5870, 1.4 on 5850) right at the cusp of 225W, the max allowed (at least by spec) to the power connectors. Bravo. Bring on the bios so everyone can flash theirs just like before...

This really is an overclockers dream
You can overclock and tweak a GPU all you like, but at some point you run out of voltage, power or cooling. This at least removes one of those problems.

Tee hee... wait for the price to drop then 4 of the 5870s in CFX with an i7 975 on H2O. (I wish)

Mmmmmmm....

What are the odds on this utility working with other brands? I guess there is nothing special in hardware, as they will all be reference cards at this point. So a simple BIOS flash should be enough to trick the software...?
