Video card maker Palit late today spoiled NVIDIA's plans for its next 500-series graphics chipset with details given out days ahead of launch. Sales sheets sent out early have shown the GeForce GTX 570, a more mainstream alternative to the GTX 580, that would potentially outperform the older GTX 480 flagship while still costing less. The design would have a lower 1.28GB of RAM and a narrower 320-bit bus, according to Kitguru's copy, but would boost the main clock speed from 700MHz to 732MHz while also using faster individual shaders and video memory.
