RD790 to gain triple and quad CrossFire capabilities

AMD is preparing to update its aging 580X chipset later this year with the upcoming RD790. The upcoming RD790 serves double duty as the single and dual processor platform of choice for AMD desktop products. RD790 introduces 41 PCIe 2.0 lanes to AMD’s Socket AM2+ platform for Stars-family processors.

Motherboard manufacturers can distribute the PCIe lanes in many configurations, including four PCIe 2.0 x16 slots with eight-lane signaling. With all 41 PCIe 2.0 lanes, the RD790 chipset has a TDP up to 10-watts. AMD roadmaps reveal the multiple PCIe 2.0 slots are used for an improved CrossFire multi-GPU technology. The improved CrossFire multi-GPU technology supports up to four ATI Radeon HD 2900 XT graphics cards in Quad CrossFire configurations.

Unlike NVIDIA’s SLI, which supports dual or quad graphics cards in SLI, the improved CrossFire solution can take on three cards for improved performance. AMD claims CrossFire scaling with three cards yields a 2.6x performance increase. Two cards in CrossFire yield a 1.8x performance improvement. AMD roadmaps do not divulge how well CrossFire scales with four GPUs.

Expect RD790 to arrive later this year in time for the AMD Phenom product launch in single and dual processor configurations.

read the article stu boy

does two 2900xt's beat the gtx yes

why does it beat the ultras in (HDR correct anti aa )

because no 8800 series will run at the above mentioned max settings

so go change your green underwear and hope the high failure rate of the 680i chipset doesn't touch you

or if you want to play call of juarez be prepared to turn it down from the max settings

no, it's because techland wouldn't bother to implement that technique in the way that works efficiently on both nv and ati chips. sorry to pour some rain on your ati parade, but once techland fixes that - the only dx10 game that artificially inflates ati score in dx10 benches will disappear, I'm afraid

then what would you do with your shiny new triple 2900xt setup, besides cooking your eggs&bacon on it of course?

slap nvidia users with it? maybe :) or use it as a paperweight, or (the best!) sell them to other ati losers, there are crowds of them around - just look at my rating going down - they are pouring in, whoooshhh... what a flow! :)

I love it

all I have to do is wait,

the ATI gpu is more flexible and if you keep reading the review's after the inital release you can see the gap closing (driver optimization)

the HD 2900 series was always supposed to be at 65nm according to roadmaps do you think they aren't still working on it

and personally all my parts are eventually moved down to my HTPC so heat and noise is always a factor to me thats why I never run NVIDIA chipsets they haven't had decent thermals since NFORCE3

and that whole pay extra for substandard pure video crap moved me away from their video cards

and they never seem to play nice with my tuners either

any way time for the commute home I'll have to complete my tirade later

regards

well you should understand there are currently 3 dx10 games

one a game performance only api move (lost planet)

1. call of juarez favors ATI (and yes there is api impelementation dispute between Techland and NVIDIA)

2. company of heroes DX10 patch favors nvidia

all the reviewers pan lost planet calling it a poor clunkie port xbox console game

so nividia has a massive one game lead

aren't they also having trouble with vista 64 somthing about open gl not functioning at all

I will give you across the board best DX9 performace ever but I think its supposed to be a DX10 card where there is no crushing dominance either

which purchase is the most future proof is it easier to code with the ATI slant (call of juarez ) or the NVIDIA slant (company of heroes)

Its really early in the DX10 game to even try to call a winner

in hardware winner today, loser tomorrow

nvidia 8800GTX/Ultra cards are 1) somewhat faster in general 2) somewhat more expensive because of that 3) came out much earlier 4) much more energy efficient

I call it a winner for today ;)

Actually, two 2900XTs do not beat "a single" 8800 GTX. Put down that red kool-aid!
