GeForce GTX 660 Ti vs Radeon RX 5600 XT

Intro

Compare all that to the Radeon RX 5600 XT, which features a core clock frequency of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also features a 192-bit bus, and uses a 7 nm design. It features 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 95520 (93%)

Pixel Rate

The Radeon RX 5600 XT will be much (more or less 301%) faster with regards to anti-aliasing than the GeForce GTX 660 Ti, and able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 66040 (301%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
