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

Texel Rate

The GeForce GTX Titan Black will be a lot (more or less 312%) more effective at anisotropic filtering 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

If running with a high resolution is important to you, then the GeForce GTX Titan Black is a better choice, and very much so. (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: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 maximum fill rate.
