GeForce GTX 780 Ti vs GeForce GTX Titan X

Intro

Compare that to the GeForce GTX Titan X, which has a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It is made up of 3072 SPUs, 192 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The GeForce GTX 780 Ti should be a bit (about 9%) better at AF 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

The GeForce GTX Titan X should be quite a bit (approximately 129%) faster with regards to full screen anti-aliasing than the GeForce GTX 780 Ti, and also able to handle higher screen resolutions better. (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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 can be applied per second. This figure is worked out by multiplying the total number of texture units 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
