GeForce GTX 980 Ti vs Nvidia Titan X


Intro

The GeForce GTX 980 Ti uses a 28 nm design. nVidia has set the core speed at 1000 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this particular model. It features 2816 SPUs as well as 176 TAUs and 96 Rasterization Operator Units.

Compare that to the Nvidia Titan X, which has a core clock frequency of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit memory bus, and makes use of a 16 nm design. It is comprised of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Nvidia Titan X should theoretically perform quite a bit faster than the GeForce GTX 980 Ti in general. (explain)

Nvidia Titan X 491520 MB/sec
GeForce GTX 980 Ti 336000 MB/sec
Difference: 155520 (46%)

Texel Rate

The Nvidia Titan X is much (about 80%) more effective at anisotropic filtering than the GeForce GTX 980 Ti. (explain)

Nvidia Titan X 317408 Mtexels/sec
GeForce GTX 980 Ti 176000 Mtexels/sec
Difference: 141408 (80%)

Pixel Rate

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

Nvidia Titan X 136032 Mpixels/sec
GeForce GTX 980 Ti 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 maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, 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 graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
