A week before the arrival of the Radeon HD 6970 and 6950, NVIDIA is getting its arsenal ready with a new derivative of the excellent GeForce GTX 580. On the menu for the GeForce GTX 570, performance levels on a par with the GeForce GTX 480 and reduced energy consumption and noise levels.
The cut down GF110
For this GeForce GTX 570, NVIDIA has of course worked with the latest revision of its high-end GPU, the GF110 A1. To recap, this is in fact a “simple” revision of the GF100 A3 used in the GeForce GTX 470 and 480. Usually this revision would have been called the GF100 B1, but for marketing reasons NVIDIA has preferred to go for a code name that inspires a feeling of innovation rather than seeming simply to be making corrections to the design of its 3 billion transistor GPU.
This GPU used in the new board is partly cut down with one of its 16 blocks of execution units disabled as well as one of its 6 memory controllers, which gives something of a mix, in terms of internal configuration, of the GeForce GTX 480 and the GeForce GTX 470, with as many processing units as the first but with a reduced memory bus like the second. Higher clocks and the several small corrections made to the GPU should allow the GeForce GTX 570 to equal the GeForce GTX 480.
