In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics Desktop (Bay Trail) are massively better than the Nvidia GeForce 4 MX 440.

The Graphics Desktop was released over three years more recently than the 4 MX, and so the Graphics Desktop 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 Graphics Desktop does not have an entry, so the two GPUs cannot be reliably compared in this area.

The HD Graphics Desktop (Bay Trail) has 4 Shader Processing Units and the GeForce 4 MX 440 has 2. However, the actual shader performance of the Graphics Desktop is 18 and the actual shader performance of the 4 MX is 1. The Graphics Desktop having 17 better shader performance and an altogether better performance when taking into account other relevant data means that the Graphics Desktop delivers a slightly smoother and more efficient experience when processing graphical data than the 4 MX.

The HD Graphics Desktop (Bay Trail) requires 10 Watts to run but there is no entry for the GeForce 4 MX 440.
