In theory, the GeForce GTX 460 SE should be 70% quicker than the Radeon HD 6670 (OEM) overall, due to its greater bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon HD 6670 (OEM)		64000 MB/sec
	Difference: 44800 (70%)

Texel Rate

The GeForce GTX 460 SE should be a lot (approximately 63%) better at AF than the Radeon HD 6670 (OEM). (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 6670 (OEM)		19200 Mtexels/sec
	Difference: 12000 (63%)

Pixel Rate

The GeForce GTX 460 SE should be quite a bit (about 225%) better at anti-aliasing than the Radeon HD 6670 (OEM), and also capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 6670 (OEM)		6400 Mpixels/sec
	Difference: 14400 (225%)

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 max amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
