GeForce GTX 780 Ti vs GeForce GTX Titan X

Intro

The GeForce GTX 780 Ti has a clock speed of 875 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit bus, and uses a 28 nm design. It is made up of 2880 SPUs, 240 TAUs, and 48 ROPs.

Compare all that to the GeForce GTX Titan X, which features a GPU core clock speed of 1000 MHz, and 12288 MB of GDDR5 RAM set to run at 1750 MHz through a 384-bit bus. It also features 3072 SPUs, 192 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The GeForce GTX 780 Ti will be a small bit (more or less 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

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan X is superior to the GeForce GTX 780 Ti, and very much so. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 is calculated by multiplying the total number of texture units by the core speed of the chip. The higher 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 most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
