Put side by side with other GeForce-based graphics cards from ASUS, the Mars III is the king of the hill. This beast of a graphics card comes with two GeForce GTX 680 GPU cores, similar to the premium GeForce GTX 690 but faster at 1006+ MHz. While the Mars III maintains 6008+ MHZ memory clock like the GTX 690 and the GTX 680, it packs the largest memory size among the three with its 8GB GDDR5. Given such immense specifications, the Mars is cooled by three fans and makes use of digital 16+ 4 phase power design.
Price- and availability-wise, details about these matters are not fully revealed at the time of writing, but according to the folks at ASUS, interested parties may start inquiring about it sometime in Q3. The Mars III, like the preceding Mars II, is going to be available in a limited number.
