GeForce GTX 780 Ti vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which features core speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X RAM. 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 should in theory be much faster than the GeForce GTX 780 Ti in general. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 780 Ti		336000 MB/sec
	Difference: 155520 (46%)

Texel Rate

The Nvidia Titan X should be a lot (more or less 51%) faster with regards to texture filtering than the GeForce GTX 780 Ti. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 780 Ti		210000 Mtexels/sec
	Difference: 107408 (51%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is superior to the GeForce GTX 780 Ti, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 94032 (224%)

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 largest amount of data (in units of MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
