GeForce GTX 980 Ti vs GeForce GTX Titan X

Intro

Compare all of that to the GeForce GTX Titan X, which features a core clock speed of 1000 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 3072 SPUs, 192 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce GTX Titan X is a bit (approximately 9%) faster with regards to anisotropic filtering than the GeForce GTX 980 Ti. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 16000 (9%)

Pixel Rate

Both cards have the exact same pixel fill rate, so in theory they should perform equally good at at anti-aliasing, and be capable of handling the same screen resolutions. (explain)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
