Radeon R7 M265 32000 MB/sec
Difference: 12800 (40%)

Texel Rate

The GeForce 8800 GT 256MB will be quite a bit (approximately 93%) better at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce 8800 GT 256MB 33600 Mtexels/sec
Radeon R7 M265 17400 Mtexels/sec
Difference: 16200 (93%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GT 256MB is the winner, by a large margin. (explain)

GeForce 8800 GT 256MB 9600 Mpixels/sec
Radeon R7 M265 5800 Mpixels/sec
Difference: 3800 (66%)

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 data (measured in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
