GeForce GTX 1660 Ti vs GeForce GTX 660 Ti

Intro

Compare that to the GeForce GTX 660 Ti, which features core speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 TAUs and 24 Rasterization Operator Units.

GeForce GTX 660 Ti		144000 MB/sec
	Difference: 150912 (105%)

Texel Rate

The GeForce GTX 1660 Ti should be a lot (approximately 41%) more effective at AF than the GeForce GTX 660 Ti. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 41520 (41%)

Pixel Rate

The GeForce GTX 1660 Ti should be quite a bit (more or less 228%) more effective at FSAA than the GeForce GTX 660 Ti, and also able to handle higher resolutions while still performing well. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 50040 (228%)

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 (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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.
