Radeon R7 M260		16000 MB/sec
	Difference: 47360 (296%)

Texel Rate

The GeForce 8800 GTS (G80) 320MB should be much (more or less 43%) faster with regards to texture filtering than the Radeon R7 M260. (explain)

GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 7464 (43%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G80) 320MB is superior to the Radeon R7 M260, by far. (explain)

GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 4540 (79%)

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 largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
