GeForce RTX 3080 vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which comes with a core clock speed of 1469 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit bus, and uses a 12 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

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

Texel Rate

The GeForce RTX 3080 is quite a bit (more or less 85%) faster with regards to texture filtering than the Radeon RX 590. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 is the winner, by a large margin. (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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
