GeForce GTX 780 Ti vs GeForce GTX Titan X

Intro

Compare that to the GeForce GTX Titan X, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1000 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this particular model. It features 3072 SPUs along with 192 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The GeForce GTX 780 Ti should be a little bit (approximately 9%) more effective at texture filtering than the GeForce GTX Titan X. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce GTX Titan X		192000 Mtexels/sec
	Difference: 18000 (9%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan X is a better choice, by a large margin. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 54000 (129%)

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 moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
