GeForce GT 310		31 Watts
Radeon RX 460 2GB		75 Watts
	Difference: 44 Watts (142%)

Memory Bandwidth

In theory, the Radeon RX 460 2GB will be 600% faster than the GeForce GT 310 overall, because of its higher bandwidth. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 96000 (600%)

Texel Rate

The Radeon RX 460 2GB will be quite a bit (approximately 1195%) faster with regards to anisotropic filtering than the GeForce GT 310. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 56328 (1195%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 460 2GB is a better choice, by a large margin. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 15084 (640%)

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 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 card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
