GeForce GTX Titan X vs Nvidia Titan X


Intro

The GeForce GTX Titan X has a GPU core speed of 1000 MHz, and the 12288 MB of GDDR5 RAM runs at 1750 MHz through a 384-bit bus. It also is made up of 3072 SPUs, 192 TAUs, and 96 ROPs.

Compare that to the Nvidia Titan X, which features a clock frequency of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also features a 384-bit memory bus, and uses a 16 nm design. It is comprised of 3584 SPUs, 224 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X will be 46% faster than the GeForce GTX Titan X overall, due to its greater bandwidth. (explain)

Nvidia Titan X 491520 MB/sec
GeForce GTX Titan X 336000 MB/sec
Difference: 155520 (46%)

Texel Rate

The Nvidia Titan X is a lot (approximately 65%) better at anisotropic filtering than the GeForce GTX Titan X. (explain)

Nvidia Titan X 317408 Mtexels/sec
GeForce GTX Titan X 192000 Mtexels/sec
Difference: 125408 (65%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is the winner, by far. (explain)

Nvidia Titan X 136032 Mpixels/sec
GeForce GTX Titan X 96000 Mpixels/sec
Difference: 40032 (42%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
