GeForce RTX 3080 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which has core speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1792 SPUs as well as 112 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 6600		132 Watts
GeForce RTX 3080		320 Watts
	Difference: 188 Watts (142%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 3080 should in theory be much superior to the Radeon RX 6600 in general. (explain)

GeForce RTX 3080		778547 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 549171 (239%)

Texel Rate

The GeForce RTX 3080 will be much (about 115%) better at texture filtering than the Radeon RX 6600. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 209568 (115%)

Pixel Rate

The GeForce RTX 3080 should be a lot (more or less 33%) more effective at full screen anti-aliasing than the Radeon RX 6600, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 34176 (33%)

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 megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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