GeForce GTX Titan Black vs GeForce GTX Titan X

Intro

The GeForce GTX Titan Black comes with clock speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 memory. It features 2880 SPUs as well as 240 Texture Address Units and 48 ROPs.

Compare all that to the GeForce GTX Titan X, which features core speeds of 1000 MHz on the GPU, and 1750 MHz on the 12288 MB of GDDR5 memory. It features 3072 SPUs along with 192 TAUs and 96 ROPs.

3DMark Fire Strike Graphics Score

GeForce GTX Titan X 17879 points
GeForce GTX Titan Black 11666 points
Difference: 6213 (53%)

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 perform the same. (explain)

Texel Rate

The GeForce GTX Titan Black will be a little bit (approximately 11%) better at AF than the GeForce GTX Titan X. (explain)

GeForce GTX Titan Black 213360 Mtexels/sec
GeForce GTX Titan X 192000 Mtexels/sec
Difference: 21360 (11%)

Pixel Rate

The GeForce GTX Titan X should be quite a bit (about 125%) better at full screen anti-aliasing than the GeForce GTX Titan Black, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX Titan X 96000 Mpixels/sec
GeForce GTX Titan Black 42672 Mpixels/sec
Difference: 53328 (125%)

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 moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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.
