GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 230784 (401%)

Texel Rate

The GeForce GTX Titan will be much (approximately 458%) better at AF than the GeForce 8800 GT 1GB. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 153888 (458%)

Pixel Rate

The GeForce GTX Titan will be quite a bit (approximately 319%) faster with regards to AA than the GeForce 8800 GT 1GB, and should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 30576 (319%)

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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
