ASUS Republic of Gamers MARS III Dual GTX 680 Pictured
ASUS is known for its crazy custom-designed graphics cards sold under the Republic of Gamers “MARS” name, and the MARS III lives up to expectations. The card is shown to sport two full NVIDIA Kepler GK104 GPUs as seen in the GeForce GTX 680 and quite possibly clocked at the full speed of 1,006 MHz, a fair bit faster than the 915 MHz seen on the GeForce GTX 690. Memory is taken care of by a total of 32 (16 per GPU) 2Gbit GDDR5 chips, which adds up to no less than 8 GB shared evenly across the two cores.
ASUS has used a PLX PEX8747 PCI-Express 3.0 bridge chip to link the two GPUs, offering 48 lanes of bandwidth for inter-core communications. The card has three 8-pin PCI-e power connectors which combined offer up to 525 watts (150 watts per connector plus 75 watts for the slot) to a 21-phase VRM setup which in turn powers the GPUs. It is not yet known whether the card will be available to the general public or if it’s simply a show of engineering, but you can be certain that if it is released it will be a very limited run and will command a very high price-tag.
