GeForce RTX 3080 Ti vs Radeon RX 570

Intro

Compare all that to the Radeon RX 570, which features clock speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 570		150 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 200 Watts (133%)

Memory Bandwidth

Theoretically, the GeForce RTX 3080 Ti should be quite a bit faster than the Radeon RX 570 overall. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 570		229376 MB/sec
	Difference: 704921 (307%)

Texel Rate

The GeForce RTX 3080 Ti is quite a bit (about 192%) more effective at AF than the Radeon RX 570. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 287296 (192%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is a better choice, by far. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 115504 (309%)

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 maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core 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 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.
