GeForce GTX 750 Ti		86400 MB/sec
	Difference: 105984 (123%)

Texel Rate

The GeForce GTX 580 3GB should be a lot (more or less 21%) better at AF than the GeForce GTX 750 Ti. (explain)

GeForce GTX 580 3GB		49408 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 8608 (21%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 580 3GB is superior to the GeForce GTX 750 Ti, by far. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
GeForce GTX 750 Ti		16320 Mpixels/sec
	Difference: 20736 (127%)

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 data (counted in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 potential to get to the max fill rate.
