GeForce GTX 980 Ti vs GeForce GTX Titan X

Intro

Compare all that to the GeForce GTX Titan X, which features GPU core speed of 1000 MHz, and 12288 MB of GDDR5 RAM set to run at 1750 MHz through a 384-bit bus. It also 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 theoretically they should have identical performance. (explain)

Texel Rate

The GeForce GTX Titan X will be a little bit (approximately 9%) better at 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 exactly the same pixel rate, so theoretically they should perform equally good at at full screen anti-aliasing, and be able to handle 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 data (counted in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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