Nvidia Titan X vs Nvidia Titan Xp

Intro

Compare all of that to the Nvidia Titan Xp, which has GPU clock speed of 1582 MHz, and 12288 MB of GDDR5X memory set to run at 1426 MHz through a 384-bit bus. It also is made up of 3840 SPUs, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Nvidia Titan Xp, in theory, should perform a bit faster than the Nvidia Titan X overall. (explain)

Nvidia Titan Xp		560845 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 69325 (14%)

Texel Rate

The Nvidia Titan Xp should be a small bit (about 20%) better at texture filtering than the Nvidia Titan X. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 62272 (20%)

Pixel Rate

If running with a high screen resolution is important to you, then the Nvidia Titan Xp is superior to the Nvidia Titan X, not by a very large margin though. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
Nvidia Titan X		136032 Mpixels/sec
	Difference: 15840 (12%)

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 (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of 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 higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
