GeForce GTX 660 Ti vs Nvidia Titan X

Intro

Compare all of that 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 RAM. It features 3584 SPUs along with 224 TAUs and 96 ROPs.

	Difference: 100 Watts (67%)

Memory Bandwidth

Performance-wise, the Nvidia Titan X should theoretically be much superior to the GeForce GTX 660 Ti in general. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 347520 (241%)

Texel Rate

The Nvidia Titan X will be much (approximately 210%) more effective at anisotropic filtering than the GeForce GTX 660 Ti. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 214928 (210%)

Pixel Rate

If running with high levels of AA is important to you, then the Nvidia Titan X is superior to the GeForce GTX 660 Ti, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 114072 (519%)

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 information (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units 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 per second.

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