Nvidia Titan X vs Nvidia Titan Xp

Intro

Compare all of that to the Nvidia Titan Xp, which has a core clock speed of 1582 MHz and a GDDR5X memory speed of 1426 MHz. It also uses a 384-bit memory bus, and makes use of a 16 nm design. It 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

As far as performance goes, the Nvidia Titan Xp should theoretically be a small bit better 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 bit (about 20%) more effective 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

The Nvidia Titan Xp should be just a bit (about 12%) more effective at AA than the Nvidia Titan X, and also should be able to handle higher resolutions without slowing down too much. (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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant 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.
