NVIDIA's Fermi architecture will start with three models if it ships before the end of the year as promised, one leak from Friday claims. A flagship single-chip model would have the 512 cores NVIDIA is advertising, but a second model would, like the GeForce GTX 295, have two slightly less powerful chipsets on one card that combined would be much faster. The slowdown may be necessary as Fudzilla believes the card would have a peak thermal power of 300W.
