The GeForce GTX 460 (OEM), in theory, should be a lot faster than the Radeon HD 3650 256MB in general. (explain)

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

Texel Rate

The GeForce GTX 460 (OEM) is a lot (more or less 528%) more effective at anisotropic filtering than the Radeon HD 3650 256MB. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
Radeon HD 3650 256MB		5800 Mtexels/sec
	Difference: 30600 (528%)

Pixel Rate

The GeForce GTX 460 (OEM) is quite a bit (about 617%) better at anti-aliasing than the Radeon HD 3650 256MB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 (OEM)		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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied 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 number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
