In theory, the GeForce GTX 460 1GB will be 86% quicker than the GeForce 8800 GTS (G92) in general, because of its higher data rate. (explain)

GeForce GTX 460 1GB		115200 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 53120 (86%)

Texel Rate

The GeForce 8800 GTS (G92) will be just a bit (more or less 10%) faster with regards to anisotropic filtering than the GeForce GTX 460 1GB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 3800 (10%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 1GB is the winner, by a large margin. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 11200 (108%)

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 largest amount of data (counted in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
