Radeon RX 5500 vs Radeon RX 570

Intro

Compare all that to the Radeon RX 570, which comes with a GPU core clock speed of 1168 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The Radeon RX 570 is a bit (more or less 2%) faster with regards to anisotropic filtering than the Radeon RX 5500. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5500 is a better choice, and very much so. (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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
