GeForce GTX Titan Black vs Nvidia Titan X

Intro

Compare all that to the Nvidia Titan X, which has core speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X memory. It features 3584 SPUs along with 224 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X will be 46% quicker than the GeForce GTX Titan Black in general, due to its higher bandwidth. (explain)

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

Texel Rate

The Nvidia Titan X should be much (more or less 49%) faster with regards to texture filtering 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 superior to the GeForce GTX Titan Black, 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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
