nVidia released the GeForce 4 MX as budget card. Practically it's nowhere near the GeForce 4 Ti but closer to the GeForce 2.

This card is the MX440-SE model which is slower. SE doesn't mean 'Special Edition' which lot's of people thought back in the time. The SE-model is an AGP-8x chip with a narrow memory bus (64-bit) which affects performance quite badly. > Read more

A 'normal' (with 128-bit memory bus) GeForce 4 MX 440. This model has an AGP 8x interface which doesn't really improve performance but is just newer technology.

The GeForce 4 MX is the budget GeForce 4 variant. It is nowhere as fast as a GeForce 4 Ti which has all the features and performance. In terms of performance the GeForce 4 MX is a bit faster than the GeForce 2 Ti or Ultra but it cannot compete with the GeForce 3. The MX is rather an advanced GeForce 2 than a stripped GeForce 4 Ti.

Despite the fact that performance and features aren't impressive, the GeForce 4 MX sold in large quantities. > Read more

A built-by-nVidia GeForce MX 440 with AGP 8x (p162nz, A2). It uses the NV18-chip which is basically identical to the NV17, except for the AGP8x bus. The NV17 only has support up to AGP4x.

Because the MX440 isn't able to even fully utilize the AGP4x bus it doesn't have benefits from AGP8x. In this case it's even worse because the AGP8x card has a 64-bit memory bus (which is most common) whereas the XFX GeForce MX 440 with AGP4x has 128-bit. > Read more
