Geforce GTX 780 vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which has core clock speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X memory. It features 3584 SPUs as well as 224 TAUs and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Nvidia Titan X should theoretically be quite a bit better than the Geforce GTX 780 in general. (explain)

Nvidia Titan X		491520 MB/sec
Geforce GTX 780		288384 MB/sec
	Difference: 203136 (70%)

Texel Rate

The Nvidia Titan X should be quite a bit (about 92%) faster with regards to AF than the Geforce GTX 780. (explain)

Nvidia Titan X		317408 Mtexels/sec
Geforce GTX 780		165696 Mtexels/sec
	Difference: 151712 (92%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is the winner, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 94608 (228%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, 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 amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
