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

Texel Rate

The GeForce GTX Titan is a bit (about 7%) faster with regards to anisotropic 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

The GeForce GTX 980 Ti will be quite a bit (about 139%) better at FSAA than the GeForce GTX Titan, and also will be capable of handling higher resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics 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 that the graphics card could possibly write to its 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 card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
