Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M375X should in theory be a lot better than the GeForce 8800 GT 512MB in general. (explain)

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

Texel Rate

The Radeon R9 M375X should be much (more or less 21%) faster with regards to texture filtering 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

The Radeon R9 M375X should be much (about 69%) better at full screen anti-aliasing than the GeForce 8800 GT 512MB, and also able to handle higher resolutions without slowing down too much. (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 max amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 processed in one second. This number 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
