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

Texel Rate

The GeForce GTX Titan should be quite a bit (more or less 72%) more effective at anisotropic filtering than the Radeon R9 280X. (explain)

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

Pixel Rate

The GeForce GTX Titan is a lot (approximately 48%) more effective at FSAA than the Radeon R9 280X, and will be able to handle higher resolutions without losing too much performance. (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 (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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