Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 is 167% quicker than the Radeon R9 M370X in general, because of its higher data rate. (explain)

GeForce GTX 580		192384 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 120384 (167%)

Texel Rate

The GeForce GTX 580 should be a lot (about 54%) better at anisotropic filtering than the Radeon R9 M370X. (explain)

GeForce GTX 580		49408 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 17408 (54%)

Pixel Rate

The GeForce GTX 580 is quite a bit (approximately 190%) better at FSAA than the Radeon R9 M370X, and also will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 24256 (190%)

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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
