In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6600 GT are significantly better than the AMD Radeon HD 2400 Pro PCI-E.

The HD 2400 was released over a year more recently than the GeForce 6600 GT, and so the HD 2400 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6600 GT.

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 HD 2400 has 128 MB more video memory than the GeForce 6600 GT, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the GeForce 6600 GT has superior memory performance.

The GeForce 6600 GT has 8.8 GB/sec greater memory bandwidth than the HD 2400, which means that the memory performance of the GeForce 6600 GT is marginally better than the HD 2400.

The Radeon HD 2400 Pro PCI-E has 40 Shader Processing Units and the GeForce 6600 GT has 11. However, the actual shader performance of the HD 2400 is 21 and the actual shader performance of the GeForce 6600 GT is 6. The HD 2400 having 15 better shader performance is not particularly notable, as altogether the GeForce 6600 GT performs better when taking into account other relevant data.

The Radeon HD 2400 Pro PCI-E requires 25 Watts to run and the GeForce 6600 GT requires 48 Watts. The GeForce 6600 GT requires 23 Watts more than the HD 2400 to run. The difference is not significant enough for the GeForce 6600 GT to have a noticeably larger impact on your yearly electricity bills than the HD 2400.
