GeForce GT 130		12000 MB/sec
	Difference: 148000 (1233%)

Texel Rate

The Radeon R9 M395X is quite a bit (about 671%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 80544 (671%)

Pixel Rate

The Radeon R9 M395X should be quite a bit (about 189%) more effective at full screen anti-aliasing than the GeForce GT 130, and also should be capable of handling higher resolutions better. (explain)

Radeon R9 M395X		23136 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 15136 (189%)

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 data (counted in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's 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 higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
