Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6670 (OEM)		63 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 87 Watts (138%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE will be 70% quicker than the Radeon HD 6670 (OEM) in general, because of its greater data rate. (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 will be quite a bit (approximately 63%) more effective at texture filtering 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 much (more or less 225%) faster with regards to full screen anti-aliasing than the Radeon HD 6670 (OEM), and also capable of handling higher resolutions while still performing well. (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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the 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 most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
