GeForce RTX 3080 vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which features GPU core speed of 1469 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Radeon RX 590		262144 MB/sec
	Difference: 516403 (197%)

Texel Rate

The GeForce RTX 3080 should be a lot (about 85%) more effective at AF than the Radeon RX 590. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 180144 (85%)

Pixel Rate

The GeForce RTX 3080 will be a lot (more or less 194%) faster with regards to full screen anti-aliasing than the Radeon RX 590, and also capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 91232 (194%)

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 largest amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
