Compare any two graphics cards:

Radeon RX 5500 vs Radeon RX 570

Intro

The Radeon RX 5500 has a GPU clock speed of 1670 MHz, and the 4096 MB of GDDR6 RAM is set to run at 14000 MHz through a 128-bit bus. It also is comprised of 1408 Stream Processors, 88 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 570, which features a GPU core clock speed of 1168 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon RX 570 is just a bit (more or less 2%) more effective at AF than the Radeon RX 5500. (explain)

Radeon RX 570		149504 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 2544 (2%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5500 is a better choice, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 16064 (43%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
