GeForce GT 130 vs GeForce GTX 580

Intro

Compare those specs to the GeForce GTX 580, which has a GPU core clock speed of 772 MHz, and 1536 MB of GDDR5 RAM set to run at 1002 MHz through a 384-bit bus. It also features 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

GeForce GT 130		75 Watts
GeForce GTX 580		244 Watts
	Difference: 169 Watts (225%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 should be much faster than the GeForce GT 130 in general. (explain)

GeForce GTX 580		192384 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 180384 (1503%)

Texel Rate

The GeForce GTX 580 will be a lot (more or less 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 high levels of AA is important to you, then the GeForce GTX 580 is the winner, and very much so. (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 data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
