GeForce RTX 3080 Ti vs Radeon RX 580

Intro

Compare those specifications to the Radeon RX 580, which features core clock 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.

GeForce RTX 3080 Ti		350 Watts
	Difference: 165 Watts (89%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 3080 Ti should theoretically be quite a bit superior to the Radeon RX 580 in general. (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 much (about 141%) more effective 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 lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is the winner, and very much so. (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 information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per 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 - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
