GeForce GTX Titan Black vs Nvidia Titan X

Intro

The GeForce GTX Titan Black features a GPU core speed of 889 MHz, and the 6144 MB of GDDR5 memory is set to run at 1750 MHz through a 384-bit bus. It also is comprised of 2880 SPUs, 240 TAUs, and 48 ROPs.

Compare those specs to the Nvidia Titan X, which uses a 16 nm design. nVidia has clocked the core speed at 1417 MHz. The GDDR5X RAM works at a frequency of 1251 MHz on this particular card. It features 3584 SPUs as well as 224 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Nvidia Titan X should theoretically be a bit superior to the GeForce GTX Titan Black in general. (explain)

Nvidia Titan X 393216 MB/sec
GeForce GTX Titan Black 336000 MB/sec
Difference: 57216 (17%)

Texel Rate

The Nvidia Titan X is a lot (more or less 49%) faster with regards to AF than the GeForce GTX Titan Black. (explain)

Nvidia Titan X 317408 Mtexels/sec
GeForce GTX Titan Black 213360 Mtexels/sec
Difference: 104048 (49%)

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is the winner, by far. (explain)

Nvidia Titan X 136032 Mpixels/sec
GeForce GTX Titan Black 42672 Mpixels/sec
Difference: 93360 (219%)

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 data (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
