GeForce GT 130		12000 MB/sec
	Difference: 60000 (500%)

Texel Rate

The Radeon R9 M275X is a lot (approximately 200%) more effective at texture filtering than the GeForce GT 130. (explain)

Radeon R9 M275X		36000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 24000 (200%)

Pixel Rate

The Radeon R9 M275X will be quite a bit (approximately 80%) more effective at FSAA than the GeForce GT 130, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 M275X		14400 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 6400 (80%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, 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 in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
