Nvidia Titan X vs Nvidia Titan Xp

Intro

Compare those specifications to the Nvidia Titan Xp, which comes with a GPU core clock speed of 1582 MHz, and 12288 MB of GDDR5X RAM 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

Theoretically speaking, the Nvidia Titan Xp should perform a bit faster than the Nvidia Titan X in general. (explain)

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

Texel Rate

The Nvidia Titan Xp should be just a bit (approximately 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

The Nvidia Titan Xp should be a little bit (approximately 12%) better at full screen anti-aliasing than the Nvidia Titan X, and also able to handle higher resolutions while still performing well. (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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
