Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X should be 25% faster than the GeForce 8800 GT 512MB overall, because of its greater data rate. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M375X is much (approximately 21%) better at AF than the GeForce 8800 GT 512MB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 7000 (21%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375X is superior to the GeForce 8800 GT 512MB, by far. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 6640 (69%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
