We already know that ASUS’s MARS II is a massive and bulky card and the impressive multiphase VRM explains all.
The MARS II embarks a 20-phase VRM: 10 phases for each group of {GF110 + 1.5GB GDDR5}. 8 phases are reserved for each GPU whereas 2 phases are dedicated for each 1.5GB of GDDR5 memory.
The specs of the beast are the following:
- GPU: 2 x GF110 @ 772MHz (2x512SP)
- Memory: 2 x 1.5GB GDDR5 @ 1000MHz, 2 x 384-bit
- Power connectors: three 8-pin PCI-E connectors
- VRM: 20 phases: 8 phases per GPU + 2 phases per GPU memory
For comparison, the GTX 590, also powered by two GF110 @ 607MHz, has 5 phases per GPU.
The price of the MARS II should be around US $1000 and only 1000 samples will be produced.
Still only 1.5GB per GPU! What is wrong with these guys?!?
It’s a shame that this video card did not come with 3GB of video ram per GPU. It would be perfect if so.

3 (6)GB memory can not make a difference
Problem?
lol you know half the people that write those things are Writers not techs 3GB would make a difference if you running multiple screens it would buffer textures ect but the app must be able to use that mem but having it in multi-desktop mode + playing games or rendering or maybe playing a game + watching a movie that is where more Video Ram will make the difference also video editing prog’s are taking advantage of GPU’s now days as well.
