Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 8800 GT 1GB should perform quite a bit faster than the Radeon R9 M375 in general. (explain)

GeForce 8800 GT 1GB		57600 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 22400 (64%)

Texel Rate

The Radeon R9 M375 is a lot (approximately 21%) more effective at texture filtering than the GeForce 8800 GT 1GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 7000 (21%)

Pixel Rate

The Radeon R9 M375 is quite a bit (more or less 69%) faster with regards to AA than the GeForce 8800 GT 1GB, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 8800 GT 1GB		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 information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
