GeForce RTX 3080 Ti vs Radeon RX 580

Intro

Compare that to the Radeon RX 580, which comes with core speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 580		185 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 165 Watts (89%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 Ti should be 256% faster than the Radeon RX 580 in general, because of its higher bandwidth. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 672153 (256%)

Texel Rate

The GeForce RTX 3080 Ti should be a lot (approximately 141%) better at AF than the Radeon RX 580. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 255792 (141%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3080 Ti is the winner, by a large margin. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 112656 (280%)

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 (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
