Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 480 should in theory be quite a bit better than the Radeon R9 M375X in general. (explain)

GeForce GTX 480		177408 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 105408 (146%)

Texel Rate

The GeForce GTX 480 will be just a bit (more or less 3%) better at anisotropic filtering than the Radeon R9 M375X. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 1400 (3%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 480 is the winner, by a large margin. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 17360 (107%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
