In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 4 MX 440 are massively better than the Nvidia GeForce 7100.

The GeForce 7100 was released over three years more recently than the 4 MX, and so the GeForce 7100 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 GeForce 7100 has 128 MB more video memory than the 4 MX, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce 7100 also has superior memory performance overall.

The GeForce 7100 has 1.6 GB/sec greater memory bandwidth than the 4 MX, which means that the memory performance of the GeForce 7100 is marginally better than the 4 MX.

Both the GeForce 7100 and the GeForce 4 MX 440 have 2 Shader Processing Units. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, we sadly do not have enough data in this area to complete the comparison.

We would recommend a PSU with at least 250 Watts for the GeForce 7100.
