GeForce GTX 1660 Ti vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which features GPU clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM set to run at 1500 MHz through a 192-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 1660 Ti		294912 MB/sec
	Difference: 49152 (17%)

Texel Rate

The Radeon RX 5600 XT should be much (about 38%) better 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 is much (about 22%) faster with regards to FSAA than the GeForce GTX 1660 Ti, and should be able to handle higher resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 amount of texture map elements (texels) that can be processed per second. This number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
