VS

Nvidia Titan X vs Nvidia Titan Xp

Intro

The Nvidia Titan X features a GPU clock speed of 1417 MHz, and the 12288 MB of GDDR5X RAM is set to run at 1251 MHz through a 384-bit bus. It also is comprised of 3584 Stream Processors, 224 TAUs, and 96 Raster Operation Units.

Compare all that to the Nvidia Titan Xp, which features 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 comprised of 3840 SPUs, 240 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the Nvidia Titan Xp should be just 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 a small bit (about 20%) faster with regards to 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 high levels of AA is important to you, then the Nvidia Titan Xp is a better choice, but only just. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
