The PCB has 13-phase VRM, 8-pin plus 6-pin power connectors, OC+ module support, and a beefy cooling solution with two 92mm fans, five 8mm thick nickel-plated copper heatpipes and an aluminium fin array.
A review by Asian tech site Expreview reveal the GeForce GTX 660 Ti Extreme delivers about the same performance as a GeForce GTX 670, making it about 12 percent faster than a standard GeForce GTX 660 Ti. The card also overclocks well, the reviewers achieved a core clockspeed of 1401MHz and 7608MHz GDDR5 with the included air cooler and overvolting.
With over-voltage, and using the air-cooling included with the card, the reviewers managed a GPU core offset of a staggering 1401 MHz, with memory frequency of 1902 MHz (7.608 GHz GDDR5-effective), resulting in a memory bandwidth of 182.6 GB/s. The card then went on to munch 3DMark 11 performance preset, yielding a score of P9232 (comparable to that of a GTX 680).
