GeForce GT 130 vs GeForce GTX 660

Intro

Compare that to the GeForce GTX 660, which features core clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 960 SPUs along with 80 Texture Address Units and 24 ROPs.

GeForce GT 130		12000 MB/sec
	Difference: 132192 (1102%)

Texel Rate

The GeForce GTX 660 should be much (approximately 553%) better at texture filtering than the GeForce GT 130. (explain)

GeForce GTX 660		78400 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 66400 (553%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 660 is the winner, by far. (explain)

GeForce GTX 660		23520 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 15520 (194%)

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 transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result 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 AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
