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.



大意是說 ASUS 這次剛搞完戰神 5870 自體 X2 這次又要搞 480 (GF100) 自體 X2

每塊 GF100晶片 可以獨立使用 1536 MB 記憶體 ，也就是說整張卡有3072MB記憶體，位寬 是 384-bit

外接電源是 3 個 8PIN ， 顯卡有用到 3 OZ 銅層技術（也就是那個主機版3OZ技術增加散熱吧）
每顆GPU用 8＋2相 供電

不過我沒看到數字供電，不知道是不是卡太熱導致不能上

關於SLI還是一樣，能 用2張MARS， 因為自體X2 因此最多是 2張SLI

最後文章說，散熱方案依然處於研究階段，因此發表日期還不知道

個人認為戰神的散熱器絕對壓制不了這東西，不可能的，大家就等待ASUS會研發出什麼恐怖的散熱器吧
希望是直接上水冷就一了百了拉
