GeForce GTX 780 Ti vs GeForce GTX Titan

Intro

Compare all of that to the GeForce GTX Titan, which makes use of a 28 nm design. nVidia has clocked the core speed at 837 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this specific model. It features 2688 SPUs as well as 224 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 780 Ti should theoretically perform just a bit faster than the GeForce GTX Titan overall. (explain)

GeForce GTX 780 Ti		336000 MB/sec
GeForce GTX Titan		288384 MB/sec
	Difference: 47616 (17%)

Texel Rate

The GeForce GTX 780 Ti should be a bit (more or less 12%) better at texture filtering than the GeForce GTX Titan. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 22512 (12%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 780 Ti is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 1824 (5%)

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 maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
