GeForce GTX 1660 Ti vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which makes use of a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 memory runs at a frequency of 1001 MHz on this card. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Texel Rate

The GeForce GTX 1660 Ti will be a lot (more or less 217%) faster with regards to AF than the GeForce GTX 560. (explain)

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

Pixel Rate

The GeForce GTX 1660 Ti should be quite a bit (approximately 178%) better at full screen anti-aliasing than the GeForce GTX 560, and will be able to handle higher resolutions more effectively. (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 max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
