GeForce RTX 3070 Ti vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which features clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Radeon RX 550		114688 MB/sec
	Difference: 508211 (443%)

Texel Rate

The GeForce RTX 3070 Ti will be quite a bit (about 759%) better at anisotropic filtering than the Radeon RX 550. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 267200 (759%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3070 Ti is a better choice, by a large margin. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 133600 (759%)

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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends 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.
