Radeon R9 M270X 72000 MB/sec
GeForce 8800 GTS (G80) 640MB 63360 MB/sec
Difference: 8640 (14%)

Texel Rate

The Radeon R9 M270X should be a bit (approximately 18%) better at anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)

Radeon R9 M270X 29000 Mtexels/sec
GeForce 8800 GTS (G80) 640MB 24624 Mtexels/sec
Difference: 4376 (18%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M270X is the winner, but only just. (explain)

Radeon R9 M270X 11600 Mpixels/sec
GeForce 8800 GTS (G80) 640MB 10260 Mpixels/sec
Difference: 1340 (13%)

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 information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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.
