GeForce RTX 3090 vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which comes with core speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 560		114688 MB/sec
	Difference: 843980 (736%)

Texel Rate

The GeForce RTX 3090 will be a lot (approximately 508%) faster with regards to AF than the Radeon RX 560. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 382360 (508%)

Pixel Rate

The GeForce RTX 3090 should be quite a bit (more or less 731%) faster with regards to full screen anti-aliasing than the Radeon RX 560, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 137440 (731%)

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 data (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
