GeForce GTX Titan vs Nvidia Titan X

Intro

The GeForce GTX Titan comes with clock speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 memory. It features 2688 SPUs as well as 224 TAUs and 48 ROPs.

Compare those specifications to the Nvidia Titan X, which uses a 16 nm design. nVidia has clocked the core frequency at 1417 MHz. The GDDR5X RAM is set to run at a frequency of 1251 MHz on this card. It features 3584 SPUs along with 224 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Nvidia Titan X, in theory, should be a lot faster than the GeForce GTX Titan in general. (explain)

Nvidia Titan X 491520 MB/sec
GeForce GTX Titan 288384 MB/sec
Difference: 203136 (70%)

Texel Rate

The Nvidia Titan X is a lot (about 69%) faster with regards to AF than the GeForce GTX Titan. (explain)

Nvidia Titan X 317408 Mtexels/sec
GeForce GTX Titan 187488 Mtexels/sec
Difference: 129920 (69%)

Pixel Rate

The Nvidia Titan X is quite a bit (about 239%) more effective at AA than the GeForce GTX Titan, and should be able to handle higher screen resolutions while still performing well. (explain)

Nvidia Titan X 136032 Mpixels/sec
GeForce GTX Titan 40176 Mpixels/sec
Difference: 95856 (239%)

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 data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied 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 higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
