GeForce GTX 660 Ti 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 memory. It features 3584 SPUs as well as 224 Texture Address Units and 96 Rasterization Operator Units.

	Difference: 100 Watts (67%)

Memory Bandwidth

Performance-wise, the Nvidia Titan X should theoretically be much better than the GeForce GTX 660 Ti overall. (explain)

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

Texel Rate

The Nvidia Titan X should be a lot (more or less 210%) better 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

The Nvidia Titan X is much (more or less 519%) faster with regards to full screen anti-aliasing than the GeForce GTX 660 Ti, and should be able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, 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 most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
