GeForce GTX 780 Ti vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which uses a 16 nm design. nVidia has set the core frequency at 1417 MHz. The GDDR5X RAM is set to run at a speed of 1251 MHz on this model. It features 3584 SPUs as well as 224 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Nvidia Titan X should in theory be quite a bit superior to the GeForce GTX 780 Ti overall. (explain)

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

Texel Rate

The Nvidia Titan X will be quite a bit (approximately 51%) more effective at 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 using a high resolution is important to you, then the Nvidia Titan X is superior to the GeForce GTX 780 Ti, by far. (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 megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 applied in a second.

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