GeForce RTX 3080 Ti vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which features core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 270 Watts (338%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti should be 715% faster than the Radeon RX 560 in general, due to its higher data rate. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 819609 (715%)

Texel Rate

The GeForce RTX 3080 Ti should be quite a bit (more or less 481%) more effective at texture filtering than the Radeon RX 560. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 361600 (481%)

Pixel Rate

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

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 134080 (713%)

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 information (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
