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 running at 1426 MHz through a 384-bit bus. It also features 3840 Stream Processors, 240 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Nvidia Titan Xp should theoretically be a small bit better 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 is a small bit (about 20%) better at AF 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 lots of anti-aliasing is important to you, then the Nvidia Titan Xp is the winner, though only just barely. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 can be applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock 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 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 reach the max fill rate.
