In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7450A are significantly better than the Nvidia GeForce 6600 GT.

The Radeon HD 7450A was released over three years more recently than the GeForce 6600 GT, and so the Radeon HD 7450A 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 Radeon HD 7450A has 896 MB more video memory than the GeForce 6600 GT, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce 6600 GT has 2.4 GB/sec greater memory bandwidth than the Radeon HD 7450A, which means that the memory performance of the GeForce 6600 GT is marginally better than the Radeon HD 7450A.

The Radeon HD 7450A has 160 Shader Processing Units and the GeForce 6600 GT has 11. However, the actual shader performance of the Radeon HD 7450A is 68 and the actual shader performance of the GeForce 6600 GT is 6. The Radeon HD 7450A having 62 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon HD 7450A delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6600 GT.

The Radeon HD 7450A requires 25 Watts to run and the GeForce 6600 GT requires 48 Watts. The GeForce 6600 GT requires 23 Watts more than the Radeon HD 7450A 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 Radeon HD 7450A.
