Introduction
Nvidia's gaming graphics cards have been slowly moving away from the old-faithful G80 chip. Now, in fact, Nvidia's latest workstation offerings are outfitted with derivatives of Nvidia's GT200 GPUs, which many have come to know through their inclusion in the cheaper mainstream GeForce GTX 260 and 280 cards.
The first entrants in this product line are the Quadro FX 5800 at the extreme high-end, with its 4 GB frame buffer, and the more "reasonably priced" Quadro FX 4800, with its 1.5 GB of graphics memory. That latter board found its way into our test labs, so that we could put it through its paces. In a few weeks, we expect to get our hands on other models in this series as well.
The FX 4800 commands a price premium of over $300 compared to the equivalent FirePro V8700 from AMD's ATI division, which online resellers retail for about $1,250. Can buyers expect a boost in features and performance for this extra outlay? First, let's take a look at the comparable cards and their speeds and feeds from both companies in the tables that follow, then we'll get around to answering this burning question.
