GeForce GTX 660 Ti vs GeForce RTX 2060 Super

Intro

Compare that to the GeForce RTX 2060 Super, which has core speeds of 1470 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 2176 SPUs as well as 136 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 660 Ti		150 Watts
GeForce RTX 2060 Super		175 Watts
	Difference: 25 Watts (17%)

Memory Bandwidth

Performance-wise, the GeForce RTX 2060 Super should in theory be quite a bit better than the GeForce GTX 660 Ti overall. (explain)

GeForce RTX 2060 Super		458752 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 314752 (219%)

Texel Rate

The GeForce RTX 2060 Super should be quite a bit (more or less 95%) more effective at anisotropic filtering than the GeForce GTX 660 Ti. (explain)

GeForce RTX 2060 Super		199920 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 97440 (95%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2060 Super is the winner, by a large margin. (explain)

GeForce RTX 2060 Super		94080 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 72120 (328%)

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 information (counted in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 memory bandwidth is, the lower the potential to get to the max fill rate.
