GeForce GT 310		31 Watts
Radeon R7 370 2G		110 Watts
	Difference: 79 Watts (255%)

Memory Bandwidth

In theory, the Radeon R7 370 2G will be 1020% faster than the GeForce GT 310 in general, due to its greater bandwidth. (explain)

Radeon R7 370 2G		179200 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 163200 (1020%)

Texel Rate

The Radeon R7 370 2G will be much (more or less 1224%) faster with regards to texture filtering than the GeForce GT 310. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 57688 (1224%)

Pixel Rate

The Radeon R7 370 2G will be much (more or less 1224%) better at AA than the GeForce GT 310, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 28844 (1224%)

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 max amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
