In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 4 MX 440 are massively better than the AMD Radeon Xpress 1150.

The Radeon Xpress 1150 was released over three years more recently than the 4 MX, and so the Radeon Xpress 1150 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 4 MX 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 4 MX has 128 MB video memory, but the Radeon Xpress 1150 does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the Radeon Xpress 1150 and the GeForce 4 MX 440 have 2 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the 4 MX is 1 and by the Radeon Xpress 1150 is 1. Knowing that the shader performance of the 4 MX is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.
