The GeForce GT 440 1.5GB will be quite a bit (more or less 146%) faster with regards to anisotropic filtering than the Radeon HD 3650 512MB. (explain)

GeForce GT 440 1.5GB		14256 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 8456 (146%)

Pixel Rate

The GeForce GT 440 1.5GB will be quite a bit (more or less 392%) faster with regards to full screen anti-aliasing than the Radeon HD 3650 512MB, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 11356 (392%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
