Radeon R9 280X		288000 MB/sec
	Difference: 48000 (17%)

Texel Rate

The GeForce GTX 780 Ti should be much (more or less 93%) faster with regards to AF than the Radeon R9 280X. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 101200 (93%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 780 Ti is a better choice, and very much so. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 14800 (54%)

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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are applied 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 better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
