First of all, the card's name should give you a clue of what to expect. The Sonic badge, much like Type-R badges on souped-up Hondas, indicates that it is from Palit's line of factory-overclocked cards. If you are wondering, and you must be, the Palit GTX 260+ Sonic comes with its core clocked at 625MHz, memory at 2200MHz DDR and shaders at 1348MHz, substantially more than the reference's clock speeds of 576MHz at the core, 1998MHz DDR at the memory, and finally, 1242MHz at the shaders. What these figures all mean is that it should perform significantly better than a reference GTX 260+.
However, sheer outright clock speeds are not the core focus in this segement. The highlight of this card has got to be its customized cooler. The cooler, at first glance, is remarkably similar to the one found the Revolution 700, except that it is slimmer and the whole card only occupies two slots in total. It features massive twin 75mm fans, which blow cool air over an elaborate heatsink with triple heat pipes and multiple fins. It looks really aggressive and we are hoping for some good temperature readings in our tests.
