Back in the month of August, we showcased for you two of the current top Pro Graphics cards in the industry, the NVIDIA Quadro FX 2000 and the ATi FireGL X1.  However, at the time we were testing those two cards, NVIDIA was readying the follow-on product to their new Quadro FX 2000, dubbed the Quadro FX 3000.  A derivative of the NV30 GPU, the Quadro FX 2000 was built upon NVIDIA's NV30GL for Workstation graphics.  In kind, NVIDIA's Quadro FX 3000 is based on their NV35GL GPU and all the enhancements its base NV35 architecture brings to the table.  Specifically, the NV35GL has a 256 bit memory bus, driving standard 850MHz DDR memory.  As we have seen with their consumer level product, this wider memory bus should significantly improve available memory bandwidth to the GPU (27.2GB/sec versus 16GB/sec for the NV30GL) and thus boost performance considerably.

Beyond that, NVIDIA also beefed up certain features of the chip, targeting it to perform in specific Professional Graphics scenarios, while offering additional features which cater to this Pro Graphics market segment.  Let's run down some of the specifications and look deeper into the Quadro FX 3000.

In our last Pro Graphics article, NVIDIA noted that they specifically enhance their "GL" products for support of things like AA points and lines, overlay planes, stereo functionality, clip regions, two sided lighting, specific hardware logic operation like hardware driven X/ORs, Hardware Stippled Lines and OpenGL quad buffered stereo.  Processing Stippled Lines for example, are not something the average consumer graphics buyer would care too much about, since they are probably not nearly as prevalent as they may be in certain CAD applications.  Essentially a "stippled" line is a broken line rendered as short dashes and sometimes dashes and dots across the screen, which can be useful in representing objects in the background or foreground of a design.

As we'll show you in the pages ahead, although NVIDIA's consumer and workstation GPUs have the same core architecture, the feature support that is bolted on to these workstation class cards, can yield significant increases in performance within various CAD and DCC applications.

Aside from that, if we didn't tell or show you the differences, you would note that on the surface, the Quadro FX 3000 sports a core GPU running at 450MHz, 256MB of DDR DRAM at 850MHz, as well Dual DVI and Stereo outputs..
