In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro FX 5600 are significantly better than the AMD Radeon X1900 GT.

The Quadro FX 5600 was released over a year more recently than the Radeon X1900 GT, and so the Quadro FX 5600 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon X1900 GT.

The Quadro FX 5600 has 1280 MB more video memory than the Radeon X1900 GT, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Quadro FX 5600 also has superior memory performance overall.

The Quadro FX 5600 has 38.4 GB/sec greater memory bandwidth than the Radeon X1900 GT, which means that the memory performance of the Quadro FX 5600 is noticeably better than the Radeon X1900 GT.

The Radeon X1900 GT has 36 Shader Processing Units and the Quadro FX 5600 has 128. However, the actual shader performance of the Radeon X1900 GT is 13 and the actual shader performance of the Quadro FX 5600 is 77. The Quadro FX 5600 having 64 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro FX 5600 delivers a noticeably smoother and more efficient experience when processing graphical data than the Radeon X1900 GT.

The Radeon X1900 GT requires 75 Watts to run and the Quadro FX 5600 requires 171 Watts. We would recommend a PSU with at least 750 Watts for the Quadro FX 5600, but we do not have a recommended PSU wattage for the Radeon X1900 GT. The Quadro FX 5600 requires 96 Watts more than the Radeon X1900 GT to run. The difference is significant enough that the Quadro FX 5600 may have an adverse affect on your yearly electricity bills in comparison to the Radeon X1900 GT.

GPU Mini Review

Mini ReviewRadeon X1900 GT is a high-end GPU based on the 90nm variant of the R500 architecture.
It's based on the R580 Core and offers 36 Pixel Shaders, 12 TMUs and 12 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 575MHz and the memory clock operates at up to 600MHz.
Its performance is relatively average but just about 1% faster than Radeon X1800 XT.
Most of today's games might be playable at medium settings although the low preset will have to suffice on some. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
A revolutionary unified architecture, NVIDIA Quadro® FX 5600 and 4600 graphics boards deliver optimized application performance. Combining the industry's most advanced feature set, including largest frame buffers, with a C programming environment, Quadro solutions solve the most complex problems. The reference standard for Shader Model 4.0, Quadro FX 5600 and 4600 enables next generation applications with unprecedented image quality.
