GeForce GTX 1660 Ti vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which has clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

GeForce GTX 560		128128 MB/sec
	Difference: 166784 (130%)

Texel Rate

The GeForce GTX 1660 Ti will be much (more or less 217%) better at anisotropic filtering than the GeForce GTX 560. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 98640 (217%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1660 Ti is a better choice, by far. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 46080 (178%)

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 data (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 bandwidth is, the lower the ability to reach the maximum fill rate.
