GeForce GTX 1660 Ti vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which comes with a core clock frequency of 1968 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 128-bit memory bus, and makes use of a 7 nm design. It features 2048 SPUs, 128 TAUs, and 64 ROPs.

Radeon RX 6600 XT		262144 MB/sec
	Difference: 32768 (13%)

Texel Rate

The Radeon RX 6600 XT should be a lot (more or less 75%) faster with regards to texture filtering than the GeForce GTX 1660 Ti. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 107904 (75%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is the winner, by a large margin. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 53952 (75%)

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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at 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 that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
