GeForce GTX 460 2GB		115200 MB/sec
	Difference: 220800 (192%)

Texel Rate

The GeForce GTX Titan Black should be a lot (about 464%) more effective at texture filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 175560 (464%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan Black is the winner, by a large margin. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 21072 (98%)

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 (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
