NVIDIA GeForce GTX 570 in December
 

The NVIDIA GeForce GTX 580 flagship, based on a fully-enabled GF110 chipset was launched on November 9. A slightly watered-down version of the GF110, or rather chips that do not meet the GeForce GTX 580 spec, will be placed on the upcoming GeForce GTX 570. The GF110 chip on the GeForce GTX 570 will have one streaming multiprocessor disabled, bringing the total CUDA core count to 480 - the same as the outgoing GeForce GTX 480. Performance is said to be around the GTX 480's level, but with a TDP quite similar to the GTX 470. No further specifications are available, but we would expect 1280MB memory on the new card.
