GeForce GTX Titan		288384 MB/sec
	Difference: 47616 (17%)

Texel Rate

The GeForce GTX Titan will be a small bit (approximately 7%) better at texture filtering than the GeForce GTX 980 Ti. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 11488 (7%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 980 Ti is superior to the GeForce GTX Titan, by a large margin. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 55824 (139%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
