GeForce GTX Titan vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which has a core clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also features a 384-bit memory bus, and makes use of a 16 nm design. It is made up of 3584 SPUs, 224 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Nvidia Titan X should theoretically perform much faster than the GeForce GTX Titan in general. (explain)

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

Texel Rate

The Nvidia Titan X will be much (more or less 69%) more effective at texture filtering than the GeForce GTX Titan. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 129920 (69%)

Pixel Rate

The Nvidia Titan X should be quite a bit (about 239%) more effective at FSAA than the GeForce GTX Titan, and also able to handle higher screen resolutions more effectively. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 95856 (239%)

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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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