The 7900GTX is the top-dog and designed to compete head-to-head against ATI’s X1900 XTX card, which it does so quite nicely. Although it has half the amount of total pixel shader units, the move to 90-nanometer means we’re seeing clock speeds ratcheted up to the point where its 24-pipelines are outpacing the competition. At the core of this GPU we really have nothing more than a refreshed 7800 – the same 24/8 pipeline setup is in place; however, the key difference is the smaller core, faster clock and lower price – certainly a recipe for success if NVIDIA played its cards right.
