At Computex 2013, the first rumors spoke of a possible custom dual-GPU card based on two GeForce GTX 770 or 760. Well, there are increasing reports that as early as next week, ASUS will release the ROG MARS 760. As the name implies, the ROG MARS 760 uses two GPUs on one PCB, which we know from the GeForce GTX 760. No final clock speeds or other specifications have been made public, but on the basis of what NVIDIA put into the GeForce GTX 760, the ASUS ROG MARS could be equipped with two 760-GK104 GPUs, each with CUDA 1,152 cores, 96 texture units and 32 ROPs.
In terms of architecture, the ROG MARS 760 and the GeForce GTX 780 should be very similar, although the former would have 64 instead of 48 ROPs. In addition, the memory configuration with 2x 2048 MB instead of only 3072 MB would be somewhat more lush. Instead of a single 384-bit memory interface, such as in the GeForce GTX 780, the ASUS ROG MARS 760 features 2x 256 bits.
The positioning of such a card is difficult. Depending on the clock, it could be a bit faster than the GeForce GTX 780 but behind the GeForce GTX Titan and GeForce GTX 780 Ti. With the ROG MARS, ASUS would not have created with a new high-end flagship, but an alternative to the fastest single GPU cards. In addition to the clock speed, questions still open are power consumption and, most importantly, the price. The ASUS ROG MARS 760 is to be officially launched next week.
