GeForce GTX Titan Black vs Nvidia Titan X


Intro

The GeForce GTX Titan Black comes with core speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 memory. It features 2880 SPUs as well as 240 TAUs and 48 ROPs.

Compare all of that to the Nvidia Titan X, which features a clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit memory bus, and uses a 16 nm design. It features 3584 SPUs, 224 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Nvidia Titan X should theoretically perform quite a bit faster than the GeForce GTX Titan Black in general. (explain)

Nvidia Titan X 491520 MB/sec
GeForce GTX Titan Black 336000 MB/sec
Difference: 155520 (46%)

Texel Rate

The Nvidia Titan X will be much (approximately 49%) better at 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 running with a high screen resolution is important to you, then the Nvidia Titan X is the winner, by a large margin. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
