Geforce GTX 780 vs Nvidia Titan X

Intro

Compare all that to the Nvidia Titan X, which comes with a core clock speed of 1417 MHz and a GDDR5X memory frequency of 1251 MHz. It also uses a 384-bit memory bus, and uses a 16 nm design. It is comprised of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Nvidia Titan X should theoretically be much superior to 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 a lot (more or less 92%) better at texture filtering 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 a better choice, and very much so. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out 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 4 instead. 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 applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
