Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan should be 0% quicker than the Radeon R9 280X overall, because of its greater data rate. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R9 280X		288000 MB/sec
	Difference: 384 (0%)

Texel Rate

The GeForce GTX Titan should be much (about 72%) more effective at AF than the Radeon R9 280X. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 78688 (72%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan is the winner, by a large margin. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 12976 (48%)

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 information (counted in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 are applied per second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs 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 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 get to the max fill rate.
