GeForce GTX Titan Black vs GeForce GTX Titan X

Intro

Compare all of that to the GeForce GTX Titan X, which comes with a clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 384-bit bus, and makes use of a 28 nm design. It is made up of 3072 SPUs, 192 TAUs, and 96 Raster Operation Units.

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 theoretically they should perform the same. (explain)

Texel Rate

The GeForce GTX Titan Black is a little bit (about 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

The GeForce GTX Titan X is much (approximately 125%) better at FSAA than the GeForce GTX Titan Black, and capable of handling higher screen resolutions better. (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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
