Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Geforce GTX 780		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 780 should perform much faster than the GeForce GT 130 in general. (explain)

Geforce GTX 780		288384 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 276384 (2303%)

Texel Rate

The Geforce GTX 780 should be quite a bit (more or less 1281%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 153696 (1281%)

Pixel Rate

If running with a high resolution is important to you, then the Geforce GTX 780 is a better choice, by far. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 33424 (418%)

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 max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 this number, the better the card will be at handling 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 the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
