Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 is 146% quicker than the Radeon R9 M370X in general, due to its greater bandwidth. (explain)

GeForce GTX 480		177408 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 105408 (146%)

Texel Rate

The GeForce GTX 480 will be quite a bit (about 31%) more effective at AF than the Radeon R9 M370X. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 10000 (31%)

Pixel Rate

The GeForce GTX 480 will be quite a bit (approximately 163%) faster with regards to anti-aliasing than the Radeon R9 M370X, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 20800 (163%)

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 largest amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
