GeForce GTX Titan Black vs GeForce GTX Titan X

Intro

The GeForce GTX Titan Black uses a 28 nm design. nVidia has clocked the core speed at 889 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this specific model. It features 2880 SPUs along with 240 Texture Address Units and 48 ROPs.

Compare those specifications to the GeForce GTX Titan X, which features clock speeds of 1000 MHz on the GPU, and 1750 MHz on the 12288 MB of GDDR5 RAM. It features 3072 SPUs as well as 192 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The GeForce GTX Titan Black is a small bit (more or less 11%) better at texture filtering 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

If using a high screen resolution is important to you, then the GeForce GTX Titan X is the winner, by far. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface within 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 must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high 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 texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at 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 could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
