ASUS Working on MARS II Dual GTX 480 Graphics Accelerator

After treating the enthusiast community to the Republic of Gamers (ROG) ARES Dual HD 5870 graphics accelerator, ASUS isn't wasting any time is designing its successor, referred to (for now) as "MARS II". This graphics accelerator uses two NVIDIA GeForce GTX 480 (GF100) GPUs on one board, that's right, the first dual-GPU accelerator based on GF100, which is dreaded for its thermal and electrical characteristics so much, that NVIDIA is content with having the second-fastest graphics card in the market (GTX 480), with no immediate plans of working on a dual-GPU accelerator.

ASUS' ambitious attempt is in the design stage deep inside its R&D, where the design is in an evaluation state. The R&D gave us some exclusive pictures of the MARS II PCB to treat you with. To begin with, the card's basic design is consistent with almost every other dual-GPU NVIDIA card in recent past. There are two independent GPU systems, each with its own VRM and memory, which are interconnected by an internal SLI, and connected to the system bus by an nForce 200 bridge chip. On this card, two GF100 GPUs with the same configuration as GeForce GTX 480 (GF100-375-A3) are used, each having 480 CUDA cores, and connecting to 1536 MB of GDDR5 memory across a 384-bit wide memory interface.

ASUS' innovations kick in right from the PCB, since it takes a lot of effort to keep such a design electrically stable, as well form an overclockers' product. MARS II uses a PCB with 3 oz copper layers to increase electrical stability, and used a strong VRM. Each GPU system is fed by an 8+2 phase VRM of its own, which use a new Super Alloy choke that reduces core energy loss. The card takes its power input from three 8-pin power inputs, which are fused.

The card is quad SLI capable, and can pair with another of its kind (and probably single GTX 480s).To cool this monstrosity, ASUS is coming up with a beefier than ever cooling solution. With the product being still at an evaluation stage, how long it will take to reach production, or whether it will in the first place, remains to be seen.

I don't even want to imagine the air cooler they'll use. Watercooling should be mandatory.

that's gonna be ridiculous.

can't wait for it .

 

[C0RR0SIVE]

Water cooling should be the stock cooling unit for that thing if it ever makes it to the market.

LOl, Im waiting for the "April fools" joke here. Dual 480's on one PCB?!? Really? That mother is going to put out some heat lmao.

And anybody notice it looks taller than a normal card? or is it just me? o_0

 

[yzmxer608]

Probably is, has to be heavier than a normal card too. 3 8 pins... That's a lot of power for one card lol.

 

[C0RR0SIVE]

It appears to be about an inch taller than a standard card, but yea, if it aint water cooled, expect tripple slot cooling.

Do I smell some mad DICE runs??

 

[Poizen22]

ooh ive been looking for a new heater. this thing will literaly make your pc a do it all . who needs t ocook eggs when you can cook a steak on that beast ???? aint nothing more fun then frying steak and playing cod lol.

All jokes aside, it might be a good thing. The possibility of this dropping the price of a 480 is 50/50.

It's only one product from one manufacturer. Wouldn't other manufacturers follow this just to make the current GTX 480 fall down in price?
