GeForce GTX 280		141696 MB/sec
	Difference: 194304 (137%)

Texel Rate

The GeForce GTX Titan Black will be much (approximately 343%) better at anisotropic filtering than the GeForce GTX 280. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 280		48160 Mtexels/sec
	Difference: 165200 (343%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan Black is the winner, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 23408 (122%)

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 largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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