In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 7050 are very slightly better than the AMD Radeon Xpress 1100 128mb.

The GeForce 7050 was released over a year more recently than the Xpress 1100, and so the GeForce 7050 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Xpress 1100.

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 GeForce 7050 and the Radeon Xpress 1100 128mb have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 7050 has 5.3 GB/sec greater memory bandwidth than the Xpress 1100, which means that the memory performance of the GeForce 7050 is marginally better than the Xpress 1100.

The GeForce 7050 has 2 Shader Processing Units but the Xpress 1100 does not have an entry, so the two GPUs cannot be reliably compared in this area.
