Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760		170 Watts
GeForce GTX 580 3GB		244 Watts
	Difference: 74 Watts (44%)

Memory Bandwidth

The GeForce GTX 580 3GB should in theory perform a little bit faster than the Geforce GTX 760 overall. (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 (more or less 90%) faster with regards to anisotropic filtering 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

If running with a high resolution is important to you, then the GeForce GTX 580 3GB is the winner, but it probably won't make a huge difference. (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 maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
