Nvidia Titan X vs Nvidia Titan Xp

Intro

Compare those specs to the Nvidia Titan Xp, which features a clock speed of 1582 MHz and a GDDR5X memory frequency of 1426 MHz. It also uses a 384-bit bus, and makes use of a 16 nm design. It is made up of 3840 SPUs, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Nvidia Titan Xp will be 14% quicker than the Nvidia Titan X overall, due to its higher bandwidth. (explain)

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

Texel Rate

The Nvidia Titan Xp is a bit (approximately 20%) more effective 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 bit (about 12%) better at FSAA than the Nvidia Titan X, and should be capable of handling higher screen 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
