Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Geforce GTX 770		230 Watts
	Difference: 155 Watts (207%)

Memory Bandwidth

In theory, the Geforce GTX 770 is 1770% quicker than the GeForce GT 130 in general, because of its higher bandwidth. (explain)

Geforce GTX 770		224384 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 212384 (1770%)

Texel Rate

The Geforce GTX 770 is quite a bit (about 1016%) more effective at AF than the GeForce GT 130. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 121888 (1016%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 770 is the winner, by far. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 25472 (318%)

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 over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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 ability to reach the max fill rate.
