The GeForce GTX 460 SE should be quite a bit (approximately 438%) faster with regards to anisotropic filtering than the Radeon HD 3650 512MB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 25400 (438%)

Pixel Rate

The GeForce GTX 460 SE will be a lot (more or less 617%) more effective at anti-aliasing than the Radeon HD 3650 512MB, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 17900 (617%)

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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
