How many different versions of 4890x2 are there going to be?
Just standard and vanilla or will we see 4Gb variants with 2Gb of GDDR5 shared inbetween?

mmmm new architecture
But not as new as we are going to see at towards the end of this year, right?Originally Posted by SNiiPE_DoGG

Right, it aint no R800 chip! Anyways, I've always thought it had to be slightly different from the RV770 rather than just clock speed changes, since this chip is called the RV790XT. A big hint there, perhaps? I'm thinking that it would actually beat the GTX 280 and perhaps even go head-to-head with the GTX 285 depending on clock speeds. At least ATI will have the fastest dual-chip card for a few months, if there's not too much of a delay...

I wouldnt be surprised if ATI actually had even lower running clocks on the RV790XT, like 725MHz or so. Notice how the 3870 ran at 775MHz and the 4870 runs at only 750MHz?

Eh?
HD3870 (RV670) was made on 55GT (high performance process) and it ran a high freq, HD4850 (RV770) is made on 55GP (general purpose, normal performance process), then how does it make sense that RV790 made also on 55GT would run slower than 55GP RV770?

LOL, didnt know that. I read about this once a while ago, but forgot.. I just thought that with all of the heat and added transistors from a bigger chip, ATI just had a harder time running it at an equally high clock. Remember how the 6800 Ultra ran at only 400MHz compared to the 5800 Ultra at 500 MHz?

well so far amd told everybody to expect a 25% boost?
so then my guess is that it has 25% more shader units?
that would make it a round 1000...
Or 1280 SPs @ a lower clockspeed to conserve power at both idle and load?
Heh, just suggesting.
I hope that there will be a dual OC version.

Which they cannot currently due without a overhaul of the current shader core...
960(12 SIMDs) or 1120(14SIMDs) would be the next steps.
I was hoping for a 40nm RV790 that would up the shaders in a SIMD from 16 to 24 but I guess that will have to wait for RV870.

Will the AMD RV790 Architecture be Something Different?
http://www.pcper.com/article.php?aid...e=expert&pid=1Initial rumors had the RV790 pegged as a speed optimized RV770, which currently powers the Radeon HD 4800 series of cards. Recent information has hinted that there is far more than a simple speed increase, and AMD could be catching us unawares with a potentially exciting new part. I take a look at AMD's releases over the past two years and make a few guesses as to what we might expect to see.
Ok, so what we have here is more rumor recycling with guessing based on info from yesteryear!
What next?

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?
What programme did you use to read the information?New info about HD 4890 ( i have sample without drivers) - 800 SP cores, 850 MHz GPU, 3600 MHz MEMs, TDP 220W, 6pin + 8pin ..., similar cooler like HD 4870 ...
But price will be very cool for that performance ... BUT YOU ALL will be surprised, what will release NV that same DAY!
Never Argue With An Idiot. They'll Lower You To Their Level And Then Beat You With Experience!
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).
@Pressure
Heh,you read my mind
Well we all know that a giant demon is holding NV forcing them to re-brand GPU's and use dishonest marketing practices...New info about HD 4890 ( i have sample without drivers) - 800 SP cores, 850 MHz GPU, 3600 MHz MEMs, TDP 220W, 6pin + 8pin ..., similar cooler like HD 4870 ...
But price will be very cool for that performance ... BUT YOU ALL will be surprised, what will release NV that same DAY!
but I doubt that demon will release NV from its clutches on April 6th.....
probably big bang XYZ
system:
Phenom II 920 3.5Ghz @ 1.4v, benchstable @ over 3,6Ghz (didnt test higher)
xigmatek achilles
sapphire hd4870 1gb @ 820 1020
Gigabyte GA-MA790GP-DS4H
8gb a-data 4-4-4-12 800
x-fi xtrememusic
rip 2x 160gb maxtor(now that adds up to 4...)
320gb/250gb/500gb samsung
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 ?
True to that. It may be launched as silently as the RV770.
Oh, first post btw
Welcome to the forums!True to that. It may be launched as silently as the RV770.

Oh men i wish Amd to stop all this sercrecy and launch the damned cards!!!!
wiw for RV790 -> better idle consumption. The PP2.0 talk was a farce.... will be enabled with later drivers... haha....
