GeForce GTX 660 Ti vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which has 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 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 5600 is 105% quicker than the GeForce GTX 660 Ti in general, due to its greater data rate. (explain)

Radeon RX 5600		294912 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 150912 (105%)

Texel Rate

The Radeon RX 5600 will be much (more or less 72%) faster with regards to AF than the GeForce GTX 660 Ti. (explain)

Radeon RX 5600		176000 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 73520 (72%)

Pixel Rate

The Radeon RX 5600 should be a lot (more or less 301%) better at full screen anti-aliasing than the GeForce GTX 660 Ti, and capable of handling higher resolutions better. (explain)

Radeon RX 5600		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 maximum amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 fill rate is also dependant 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 maximum fill rate.
