In terms of overall gaming performance, the graphical capabilities of the AMD Radeon Xpress X200 are noticeably better than the Nvidia GeForce 6150 SE 256MB.

The 6150 SE was released over a year more recently than the Radeon Xpress X200, and so the 6150 SE is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon Xpress X200.

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 6150 SE has 256 MB video memory, but the Radeon Xpress X200 does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the Radeon Xpress X200 and the GeForce 6150 SE 256MB have 2 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the 6150 SE is 1 and by the Radeon Xpress X200 is 1. Knowing that the shader performance of the 6150 SE is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.
