Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 8800 GTX should in theory be just a bit better than the Radeon R9 M375X overall. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The Radeon R9 M375X is a bit (more or less 10%) more effective at AF than the GeForce 8800 GTX. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 3800 (10%)

Pixel Rate

The Radeon R9 M375X is a little bit (about 18%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTX, and also capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 2440 (18%)

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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
