Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 480 will be 404% quicker than the Radeon R9 M375 overall, due to its greater data rate. (explain)

GeForce GTX 480		177408 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 142208 (404%)

Texel Rate

The GeForce GTX 480 will be a little bit (about 3%) more effective at anisotropic filtering than the Radeon R9 M375. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 1400 (3%)

Pixel Rate

The GeForce GTX 480 should be quite a bit (about 107%) faster with regards to FSAA than the Radeon R9 M375, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon R9 M375		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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 potential to get to the maximum fill rate.
