Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black should be 40% faster than the Radeon R9 280 in general, because of its higher data rate. (explain)

GeForce GTX Titan Black		336000 MB/sec
Radeon R9 280		240000 MB/sec
	Difference: 96000 (40%)

Texel Rate

The GeForce GTX Titan Black should be quite a bit (about 104%) more effective at AF than the Radeon R9 280. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 108864 (104%)

Pixel Rate

If using a high resolution 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
Radeon R9 280		29856 Mpixels/sec
	Difference: 12816 (43%)

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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. 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 better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
