GeForce GTX Titan Black vs GeForce GTX Titan X

Intro

The GeForce GTX Titan Black has a GPU clock speed of 889 MHz, and the 6144 MB of GDDR5 RAM is set to run at 1750 MHz through a 384-bit bus. It also is made up of 2880 Stream Processors, 240 Texture Address Units, and 48 Raster Operation Units.

Compare all that to the GeForce GTX Titan X, which uses a 28 nm design. nVidia has set the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this particular card. It features 3072 SPUs along with 192 TAUs and 96 Rasterization Operator Units.

These are real-world performance benchmarks that were submitted by Hardware Compare users. The scores seen here are the average of all benchmarks submitted for each respective test and hardware.

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 bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The GeForce GTX Titan Black should be a little bit (more or less 11%) more effective at anisotropic 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 lots of anti-aliasing is important to you, then the GeForce GTX Titan X is a better choice, by a large margin. (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 (counted in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, 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 figure is worked out by multiplying the total amount of texture units of the card by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
