GeForce GTX Titan Black vs GeForce GTX Titan X

Intro

Compare those specifications to the GeForce GTX Titan X, which has a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is comprised of 3072 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

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 will be a small bit (more or less 11%) better 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

The GeForce GTX Titan X is quite a bit (approximately 125%) better at anti-aliasing than the GeForce GTX Titan Black, and should be capable of handling higher screen resolutions while still performing well. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
