The Quadro FX
Our tour of the Quadro GPUs start with the top model, the FX 5800. Based on the same GPU architecture as the GTX 200 series and with the same stream processor count (240) as the GTX 280, it's without a doubt the most powerful single GPU workstation card from NVIDIA and it's reflected in its US$3499 price tag. There are some crucial differences of course, chief being the 4GB DDR3 memory that is found on the FX 5800, four times that of the GTX 280. The memory bandwidth too is lower than the typical GTX 280, but the interface remains at 512-bit wide.
The maximum TDP on the FX 5800 is also lower than the GTX 280, though two power connectors are still required. Rear outputs are changed from the standard GTX 280, with the addition of a DisplayPort and a 3D stereo port for professional stereo display options (such as 3D glasses and 3D displays).
The Quadro FX 4800 meanwhile is the GTX 260 equivalent in the Quadro family, with 192 stream processors, meaning it's akin to the original GTX 260 and not the enhanced 216-core version in the consumer segment at the moment. Similar to the Quadro FX 5800, its memory bandwidth is reduced from that on the consumer gaming card though the frame buffer is increased to 1.5GB. It remains costly at US$1999 until you compare it to the FX 5800.
