Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTX 950		90 Watts
	Difference: 15 Watts (20%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950 should be much faster than the GeForce GT 130 overall. (explain)

GeForce GTX 950		105728 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 93728 (781%)

Texel Rate

The GeForce GTX 950 is quite a bit (more or less 310%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 37152 (310%)

Pixel Rate

The GeForce GTX 950 should be much (approximately 310%) better at FSAA than the GeForce GT 130, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 24768 (310%)

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 maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
