Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M265X should be 350% quicker than the GeForce GT 310 overall, because of its greater bandwidth. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M265X is a lot (about 388%) faster with regards to texture filtering than the GeForce GT 310. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 18288 (388%)

Pixel Rate

The Radeon R9 M265X is a lot (about 290%) more effective at AA than the GeForce GT 310, and should be capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M265X		9200 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 6844 (290%)

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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 get to the maximum fill rate.
