	Difference: 74 Watts (44%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 3GB should be 0% faster than the Geforce GTX 760 overall, because of its higher data rate. (explain)

GeForce GTX 580 3GB		192384 MB/sec
Geforce GTX 760		192256 MB/sec
	Difference: 128 (0%)

Texel Rate

The Geforce GTX 760 should be much (about 90%) better at AF than the GeForce GTX 580 3GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 44672 (90%)

Pixel Rate

The GeForce GTX 580 3GB is a small bit (approximately 18%) more effective at full screen anti-aliasing than the Geforce GTX 760, and capable of handling higher screen resolutions better. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
Geforce GTX 760		31360 Mpixels/sec
	Difference: 5696 (18%)

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 moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 number 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 clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
