GeForce RTX 2080 SUPER vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which has a clock speed of 1626 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It features 1792 SPUs, 112 TAUs, and 64 Raster Operation Units.

Radeon RX 6600		132 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 118 Watts (89%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER is 121% faster than the Radeon RX 6600 overall, due to its greater bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 278528 (121%)

Texel Rate

The GeForce RTX 2080 SUPER will be quite a bit (about 74%) faster with regards to AF than the Radeon RX 6600. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 134688 (74%)

Pixel Rate

The GeForce RTX 2080 SUPER is a bit (more or less 1%) more effective at AA than the Radeon RX 6600, and should be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 1536 (1%)

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 largest amount of data (in units of MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
