Texel Rate

The GeForce GTX Titan Black will be quite a bit (about 96%) better at anisotropic filtering than the Radeon R9 280X. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 104560 (96%)

Pixel Rate

The GeForce GTX Titan Black will be a lot (about 57%) more effective at full screen anti-aliasing than the Radeon R9 280X, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 15472 (57%)

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 information (measured in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
