Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Radeon R9 M295X		125 Watts
	Difference: 50 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X is 1367% quicker than the GeForce GT 130 in general, because of its greater data rate. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 164000 (1367%)

Texel Rate

The Radeon R9 M295X should be a lot (more or less 700%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 84000 (700%)

Pixel Rate

The Radeon R9 M295X should be quite a bit (about 200%) better at anti-aliasing than the GeForce GT 130, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 16000 (200%)

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 over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 can be applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
