GeForce GT 130		75 Watts
Radeon R9 270X		180 Watts
	Difference: 105 Watts (140%)

Memory Bandwidth

In theory, the Radeon R9 270X should be 1393% quicker than the GeForce GT 130 in general, due to its greater bandwidth. (explain)

Radeon R9 270X		179200 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 167200 (1393%)

Texel Rate

The Radeon R9 270X should be a lot (about 567%) more effective at anisotropic filtering than the GeForce GT 130. (explain)

Radeon R9 270X		80000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 68000 (567%)

Pixel Rate

The Radeon R9 270X will be a lot (more or less 300%) better at anti-aliasing than the GeForce GT 130, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 270X		32000 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 24000 (300%)

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 (counted in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the ability to get to the maximum fill rate.
