In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6600 GT are very slightly better than the Nvidia GeForce FX 5600 Ultra.

The GeForce 6600 GT was released over a year more recently than the FX 5600, and so the GeForce 6600 GT is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the FX 5600.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce FX 5600 Ultra and the GeForce 6600 GT have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 6600 GT has 9.6 GB/sec greater memory bandwidth than the FX 5600, which means that the memory performance of the GeForce 6600 GT is marginally better than the FX 5600.

The GeForce FX 5600 Ultra has 4 Shader Processing Units and the GeForce 6600 GT has 11. However, the actual shader performance of the FX 5600 is 1 and the actual shader performance of the GeForce 6600 GT is 6. The GeForce 6600 GT having 5 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 6600 GT delivers a marginally smoother and more efficient experience when processing graphical data than the FX 5600.

The GeForce 6600 GT requires 48 Watts to run but there is no entry for the FX 5600.
