In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 5450 Asus Silent 1GB Edition are significantly better than the Nvidia GeForce 6600 GT.

The HD 5450 was released over three years more recently than the GeForce 6600 GT, and so the HD 5450 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 5450 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, overall, the GeForce 6600 GT has superior memory performance.

The GeForce 6600 GT has 8 GB/sec greater memory bandwidth than the HD 5450, which means that the memory performance of the GeForce 6600 GT is marginally better than the HD 5450.

The Radeon HD 5450 Asus Silent 1GB Edition has 80 Shader Processing Units and the GeForce 6600 GT has 11. However, the actual shader performance of the HD 5450 is 52 and the actual shader performance of the GeForce 6600 GT is 6. The HD 5450 having 46 better shader performance is not particularly notable, as altogether the GeForce 6600 GT performs better when taking into account other relevant data.

The GeForce 6600 GT requires 48 Watts to run but there is no entry for the HD 5450.
