GeForce GTX 650 80000 MB/sec
GeForce 8800 GT 1GB 57600 MB/sec
Difference: 22400 (39%)

Texel Rate

The GeForce GTX 650 is a small bit (approximately 1%) better at AF than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 650 33856 Mtexels/sec
GeForce 8800 GT 1GB 33600 Mtexels/sec
Difference: 256 (1%)

Pixel Rate

The GeForce GTX 650 is much (more or less 76%) faster with regards to full screen anti-aliasing than the GeForce 8800 GT 1GB, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 650 16928 Mpixels/sec
GeForce 8800 GT 1GB 9600 Mpixels/sec
Difference: 7328 (76%)

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: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
