Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTX should be a bit faster 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 will be just a bit (approximately 10%) more effective at anisotropic filtering 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 small bit (about 18%) faster with regards to FSAA than the GeForce 8800 GTX, and should be able to handle higher 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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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