GeForce GTX 660 vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which features core speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X RAM. It features 3584 SPUs along with 224 Texture Address Units and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 660		140 Watts
Nvidia Titan X		250 Watts
	Difference: 110 Watts (79%)

Memory Bandwidth

The Nvidia Titan X, in theory, should perform much faster than the GeForce GTX 660 overall. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 660		144192 MB/sec
	Difference: 347328 (241%)

Texel Rate

The Nvidia Titan X should be a lot (about 305%) better at texture filtering than the GeForce GTX 660. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 660		78400 Mtexels/sec
	Difference: 239008 (305%)

Pixel Rate

If running with high levels of AA 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 660		23520 Mpixels/sec
	Difference: 112512 (478%)

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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
