Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260X, in theory, should be much faster than the GeForce GT 310 in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon R7 M260X should be much (about 320%) better at AF than the GeForce GT 310. (explain)

Radeon R7 M260X		19800 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 15088 (320%)

Pixel Rate

The Radeon R7 M260X is a lot (approximately 180%) better at FSAA than the GeForce GT 310, and will be capable of handling higher resolutions more effectively. (explain)

Radeon R7 M260X		6600 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 4244 (180%)

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 MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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