In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 765M are massively better than the AMD Mobility Radeon 9000 64MB.

The GeForce GTX 765M was released over three years more recently than the Radeon 9000, and so the GeForce GTX 765M is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon 9000 when running the latest games.

The GeForce GTX 765M has 1984 MB more video memory than the Radeon 9000, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 765M also has superior memory performance overall.

The GeForce GTX 765M has 60.9 GB/sec greater memory bandwidth than the Radeon 9000, which means that the memory performance of the GeForce GTX 765M is much better than the Radeon 9000.

The GeForce GTX 765M has 768 Shader Processing Units and the Mobility Radeon 9000 64MB has 1. However, the actual shader performance of the GeForce GTX 765M is 653 and the actual shader performance of the Radeon 9000 is 0. The GeForce GTX 765M having 653 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 765M delivers a massively smoother and more efficient experience when processing graphical data than the Radeon 9000.

The GeForce GTX 765M requires 65 Watts to run but there is no entry for the Mobility Radeon 9000 64MB.
