In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 3400 Series are significantly better than the Nvidia GeForce 6600 GT.

The HD 3400 was released over three years more recently than the GeForce 6600 GT, and so the HD 3400 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6600 GT when running the latest games.

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 3400 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 15.2 GB/sec greater memory bandwidth than the HD 3400, which means that the memory performance of the GeForce 6600 GT is slightly better than the HD 3400.

The Radeon HD 3400 Series has 40 Shader Processing Units and the GeForce 6600 GT has 11. However, the actual shader performance of the HD 3400 is 16 and the actual shader performance of the GeForce 6600 GT is 6. The HD 3400 having 10 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 3400 Series requires 65 Watts to run and the GeForce 6600 GT requires 48 Watts. The HD 3400 requires 17 Watts more than the GeForce 6600 GT to run. The difference is not significant enough for the HD 3400 to have a noticeably larger impact on your yearly electricity bills than the GeForce 6600 GT.
