A supposed leaked slide has reared its face online, possibly one of many taken from a Nvidia partner presentation detailing Nvidia's upcoming dual-GPU graphics card, the GeForce GTX 590. The leak arrives just after AMD launched its Radeon HD 6990 graphics card sporting dual Cayman GPUs, a dual-BIOS toggle switch, and a hefty $699 pricetag.
According to the slide, the GeForce GTX 590 will feature a 12 layer, 2-oz copper printed circuit board (PCB) designed with a 10-phase power layout. There's also dual vapor chambers, 3 GB of GDDR5 memory (1.5 GB per GPU) and a PCIe dual x16 custom bridge chip. Oh and let's not forget the two GF110 GPUs with a total 1024 (2 x 512) CUDA cores.
To round out Nvidia's big 11-inch package, a removable cover will allow for easy cleaning. It also seems to reveal three DVI ports, possibly for 3D Vision Surround, and a dual-slot center-fan design that blows the air to the GPUs seated on the left and right.
The card will also require additional power through two 8-pin PCIe power connectors. If it's anything like AMD's monster Radeon HD 6990, the parent rig will need a 750W power supply at the least, 1200W for optimal performance. What's surprising is that the card comes packed with 1 GB less memory than AMD's offering, leading us to wonder if the slide may be mistaken.
Currently the Nvidia GeForce GTX 590 is rumored to be shipping on March 22, mere weeks away. We're still waiting on something official to trickle through the Nvidia lines, so stay tuned.
And we are still waiting for the card to trickle down to you all so you can review it for us! =)
Sounds more like a race car!
Kevin, would you care to explain what is surprising ? Nvidia's GTX580 card, which is the base for this card, was designed like that; adding memory would result in either a 6GB card (3Gb per GPU), or a memory system redesign.
Is this - the card should come with 6GB - what you mean ?
It's been rumored for some time that the GTX590 would feature 3GB GDDR5, and this makes perfect sense as the GTX580 has 1.5GB on a 384-bit mem interface. So I'm not sure why this alone would lead anyone to question the legitimacy of the slides. The only way 4GB would be possible is if the bus width on the GTX590 were downgraded to 2x 256-bit, or bumped up to 2x 512-bit, neither of which seem remotely likely.
I can't see how it can "only" do with two 8-pin connectors, not unless it's being significantly downclocked. I checked Anandtech's power readings for their 6990 review and the 6990 uses 130W less power than two 580s playing Crysis, and considering AMD throttle their cards for FurMark, the stock 6990 uses 300W less power in comparison (using the OC BIOS still results in 166W lower drain). The removable cover is a nice touch. All in all, this card isn't going to be cheap and I reiterate that I can't see it being fully clocked - hell, even the 6990 isn't all that.
22nd March is just next Tuesday so we don't have long to wait for answers.
By putting both gpus on one board you eliminate ALOT of redundant circuitry which helps them maintain the lower than you would expect power envelope without having to downclock too severely. I think it will be a safe bet that this will both out perform and out cost the 6990
Jury is out on noise and heat until some review get up
