GeForce GTX 285 1GB		158976 MB/sec
	Difference: 177024 (111%)

Texel Rate

The GeForce GTX Titan Black should be quite a bit (more or less 312%) faster with regards to AF than the GeForce GTX 285 1GB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 285 1GB		51840 Mtexels/sec
	Difference: 161520 (312%)

Pixel Rate

The GeForce GTX Titan Black should be much (about 106%) more effective at AA than the GeForce GTX 285 1GB, and should be capable of handling higher screen resolutions better. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 285 1GB		20736 Mpixels/sec
	Difference: 21936 (106%)

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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
