While sales in the high end market are only a small portion of revenue streams, both nVidia and AMD are keen to be seen to dominate. With the imminent release of AMD's 6900 Cayman cards we thought it was a good time to have a look at the performance of this card within several systems.
The GTX 580 is a 3 billion transistor design which demands significant power, although nVidia have made changes to the architecture to ensure that latencies and electrical leakages are reduced. The Geforce GTX580 has 512 cuda cores (an increase from 480 on the Geforce GTX480) and it also features 64 texture memory units and 48 ROP's via a 384 bit memory interface with 1.5GB of GDDR5 memory onboard.
