if ati/amd release a 1gb model on launch day... i'll have 2.... :)
and my old 4870's will go towards the robot im building in the corner of my room...

Wouldn't it be nice if this site had dig and dugg features? :)
I still remember how all the GPU utilities/apps. showed RV770 as a 480SP GPU,even after it launched.It took some time for it to be recognized as 800SP part.So OBR,maybe you are not seeing it right^^(not implying RV790 is a SP-improved RV770,just saying never say never again :D).

Heh,you read my mind :D
probably big bang XYZ ;)
Problem 1: If it were 220W it would definitely need 8pin + 8pin.
Problem 2: 100Mhz bump does not justify 220W (50W EXTRA) neither.
I do not want to seem very doubtful or wishful, but couldn't it hapen that whatever he used to get the info from the card (unless it was in the docs) did not show the correct details ?
wiw for RV790 -> better idle consumption. The PP2.0 talk was a farce.... will be enabled with later drivers... haha....
Hornet331,
The thing with RV770's idle consumption is, GDDR5 is to blame. RV770 GPU chip is very power efficient in idle and manual downclocking of the VRAM will drop the consumption to sub-30W figures. HD4850 idles around 25W at stock, without manual tampering...
Here's Josh's take on RV790.

A Bit of History
The other day Fudzilla reported that the RV790 was far more than a faster clocked version of the current RV770 which powers the Radeon 4800 series. Initial reports were that the RV790 was to be a slightly optimized RV770 which would run around 150 to 200 MHz faster in core clock speed. Nothing terribly exciting to see here. Or so we were led to believe...
AMD will simply look foolish if the new card requires 6+8 pin PEG connectors, considering nVidia's success making GTX 285 into a 6+6 pin PEG connectors compliant card. And unless GDDR5 gets worse as it gets ramped up, the added VRAM capacity shouldn't affect the TDP THAT bad. But commenting on an attention wh*re poster is just like feeding a troll, perhaps i shouldn't even write this post, huh. :down:
This is the biggest piece I've seen on a product that no one knows anything about but it offers some great insight into the thought and design process of ATI's release relative to Nvidia.

Latest rumor from reliable source says nVidia wants to put a GTX275 against the HD4890. If true that also says something about RV790 performance.
Is that the card nVidia wants to launch the same day as ATI, OBR?
its definitely interesting how they predict what a card would be like if it was built a little larger on the 40nm node, just by doing some math. AMD/ATI did something great with the R700s, now keep it up for dx11 and opencl, and maybe my stock will go back up a little.
What I honestly think is that if the new chip was just an overclocked RV770, they wouldn't give it a different codename.
AFAIK, ATI never did that with codenames.
How many RV790 theads do we need for any new speculation?
We already have this speculation in two of the others:
