GeForce GTX 780 Ti vs GeForce GTX Titan Black

Intro

The GeForce GTX 780 Ti features a core clock speed of 875 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit bus, and uses a 28 nm design. It is made up of 2880 SPUs, 240 Texture Address Units, and 48 ROPs.

Compare all that to the GeForce GTX Titan Black, which features a core clock frequency of 889 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 384-bit bus, and makes use of a 28 nm design. It features 2880 SPUs, 240 Texture Address Units, and 48 ROPs.

3DMark Fire Strike Graphics Score

GeForce GTX Titan Black 11666 points
GeForce GTX 780 Ti 10900 points
Difference: 766 (7%)

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The GeForce GTX Titan Black will be a bit (about 2%) better at anisotropic filtering than the GeForce GTX 780 Ti. (explain)

GeForce GTX Titan Black 213360 Mtexels/sec
GeForce GTX 780 Ti 210000 Mtexels/sec
Difference: 3360 (2%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX Titan Black is the winner, but not by far. (explain)

GeForce GTX Titan Black 42672 Mpixels/sec
GeForce GTX 780 Ti 42000 Mpixels/sec
Difference: 672 (2%)

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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred across 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 memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 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 higher this number, the better the video 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 number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 potential to get to the maximum fill rate.
