Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X is 350% quicker than the GeForce GT 310 overall, due to its higher data rate. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M370X will be quite a bit (more or less 579%) better at AF than the GeForce GT 310. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 27288 (579%)

Pixel Rate

The Radeon R9 M370X is quite a bit (approximately 443%) faster with regards to anti-aliasing than the GeForce GT 310, and should be able to handle higher resolutions better. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 10444 (443%)

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 (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its 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 core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
