GeForce GTX 780 Ti vs GeForce GTX Titan Black

Intro

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

Compare those specifications to the GeForce GTX Titan Black, which features a GPU core clock speed of 889 MHz, and 6144 MB of GDDR5 memory running at 1750 MHz through a 384-bit bus. It also features 2880 Stream Processors, 240 Texture Address Units, and 48 Raster Operation Units.

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

Texel Rate

The GeForce GTX Titan Black will be a small bit (more or less 2%) faster with regards to AF 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, not by a very large margin though. (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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
