Radeon HD 3650 256MB		78 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 72 Watts (92%)

Memory Bandwidth

In theory, the GeForce GTX 460 SE should be 325% faster than the Radeon HD 3650 256MB overall, because of its greater bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon HD 3650 256MB		25600 MB/sec
	Difference: 83200 (325%)

Texel Rate

The GeForce GTX 460 SE will be a lot (about 438%) more effective at anisotropic filtering than the Radeon HD 3650 256MB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 3650 256MB		5800 Mtexels/sec
	Difference: 25400 (438%)

Pixel Rate

The GeForce GTX 460 SE should be much (more or less 617%) more effective at AA than the Radeon HD 3650 256MB, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 3650 256MB		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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the 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 core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
