GeForce GTX 1660 Ti vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which features core clock speeds of 1375 MHz on the GPU, and 14000 MHz on the 6144 MB of GDDR6 RAM. It features 2304 SPUs as well as 144 TAUs and 64 ROPs.

Texel Rate

The Radeon RX 5600 XT is a lot (more or less 38%) more effective at texture filtering than the GeForce GTX 1660 Ti. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce GTX 1660 Ti		144000 Mtexels/sec
	Difference: 54000 (38%)

Pixel Rate

The Radeon RX 5600 XT should be much (more or less 22%) more effective at full screen anti-aliasing than the GeForce GTX 1660 Ti, and also should be able to handle higher screen resolutions better. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 16000 (22%)

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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
