In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce4 Ti 4200 are significantly better than the Nvidia GeForce 4 MX 440.
The GeForce4 Ti 4200 was released less than a year after the 4 MX, and so they are likely to have similar driver support for optimizing performance 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 GeForce4 Ti 4200 and the GeForce 4 MX 440 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The 4 MX has 1.4 GB/sec greater memory bandwidth than the GeForce4 Ti 4200, which means that the memory performance of the 4 MX is marginally better than the GeForce4 Ti 4200.
The GeForce4 Ti 4200 has 4 Shader Processing Units and the GeForce 4 MX 440 has 2. 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.
GeForce4 Ti 4200 is part of the GeForce4 GPUS released by NVIDIA in 2002. Only compatible with DirectX 8.1 or less and with a max memory of 128 MB, it can't play today's games.
Still, games before 2004 should be fully playable at max settings.
GeForce4 MX 440 is part of the GeForce4 GPUS released by NVIDIA in 2002. Only compatible with DirectX 7 or less and with a max memory of 128 MB, it can't play today's games.
Still, games before 2003 should be fully playable at max settings....
