The Tech Report spotted rumors regarding the overclocking capabilities of NVIDIA's upcoming GeForce GTX 460 (GF104):
The folks at Heise Online say overclocking experiments in East Asia have shown the GF104-based GeForce GTX 460 can climb from a stock 675MHz speed to 830MHz without a voltage bump. If you do raise the voltage a little bit, the card can reportedly hit 900MHz. At that speed, Heise Online claims the GTX 460 beats the existing, GF100-based GeForce GTX 470.
That sounds like quite a feat for a card that's supposed to retail at around $230. Incidentally, Heise Online's story mentions not one, but two GTX 460 variants: the $230 one we've already heard about, with 768MB of RAM and a 192-bit memory interface, as well as a more upscale, $250 model with a full 1GB of RAM and 256-bit path to memory.
