Radeon RX 5500 vs Radeon RX 570

Intro

Compare those specifications to the Radeon RX 570, which comes with a clock frequency of 1168 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and uses a 14 nm design. It features 2048 SPUs, 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 bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon RX 570 should be a little 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 using lots of anti-aliasing is important to you, then the Radeon RX 5500 is superior to the Radeon RX 570, 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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
