Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X should be 14% faster than the GeForce 8800 GTS (G80) 640MB in general, because of its greater data rate. (explain)

Radeon R9 M375X 72000 MB/sec
GeForce 8800 GTS (G80) 640MB 63360 MB/sec
Difference: 8640 (14%)

Texel Rate

The Radeon R9 M375X is a lot (more or less 65%) faster with regards to anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)

Radeon R9 M375X 40600 Mtexels/sec
GeForce 8800 GTS (G80) 640MB 24624 Mtexels/sec
Difference: 15976 (65%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M375X is a better choice, by far. (explain)

Radeon R9 M375X 16240 Mpixels/sec
GeForce 8800 GTS (G80) 640MB 10260 Mpixels/sec
Difference: 5980 (58%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must 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 applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
