GeForce GT 130		12000 MB/sec
	Difference: 180384 (1503%)

Texel Rate

The GeForce GTX 580 will be a lot (approximately 312%) more effective at anisotropic filtering than the GeForce GT 130. (explain)

GeForce GTX 580		49408 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 37408 (312%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 580 is the winner, by far. (explain)

GeForce GTX 580		37056 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 29056 (363%)

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 (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
