GeForce GTX 660 Ti vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which makes use of a 16 nm design. nVidia has set the core speed at 1417 MHz. The GDDR5X RAM is set to run at a frequency of 1251 MHz on this particular card. 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 Ti		150 Watts
Nvidia Titan X		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should be 241% quicker than the GeForce GTX 660 Ti overall, due to its greater data rate. (explain)

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

Texel Rate

The Nvidia Titan X is a lot (about 210%) faster with regards to texture 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 should be much (about 519%) faster with regards to AA than the GeForce GTX 660 Ti, and should be able to handle higher screen resolutions without slowing down too much. (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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
