GeForce GTX 980 Ti vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which comes with a clock frequency of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit bus, and makes use of a 16 nm design. It is made up of 3584 SPUs, 224 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Nvidia Titan X should in theory be quite a bit faster than the GeForce GTX 980 Ti overall. (explain)

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

Texel Rate

The Nvidia Titan X will be much (approximately 80%) more effective at texture 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 resolution is important to you, then the Nvidia Titan X is a better choice, 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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. 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 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 get to the maximum fill rate.
