GeForce 8800 GT 256MB 44800 MB/sec
Radeon R7 M265 32000 MB/sec
Difference: 12800 (40%)

Texel Rate

The GeForce 8800 GT 256MB will be quite a bit (more or less 93%) faster with regards to 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 using high levels of AA is important to you, then the GeForce 8800 GT 256MB is superior to the Radeon R7 M265, by far. (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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
