GeForce GTX 1660 Ti vs GeForce RTX 3060

Intro

Compare all that to the GeForce RTX 3060, which has clock speeds of 1320 MHz on the GPU, and 1875 MHz on the (Unknown) MB of GDDR6 RAM. It features 3584 SPUs as well as 112 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1660 Ti		120 Watts
GeForce RTX 3060		170 Watts
	Difference: 50 Watts (42%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 3060 should in theory be a lot superior to the GeForce GTX 1660 Ti in general. (explain)

GeForce RTX 3060		368640 MB/sec
GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 73728 (25%)

Texel Rate

The GeForce RTX 3060 is just a bit (approximately 3%) more effective at texture filtering than the GeForce GTX 1660 Ti. (explain)

GeForce RTX 3060		147840 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 3840 (3%)

Pixel Rate

The GeForce GTX 1660 Ti should be a small bit (more or less 14%) faster with regards to FSAA than the GeForce RTX 3060, and will be able to handle higher screen resolutions better. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce RTX 3060		63360 Mpixels/sec
	Difference: 8640 (14%)

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 max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
