Radeon RX 5500 vs Radeon RX 570

Intro

Compare all of that to the Radeon RX 570, which features a core clock frequency of 1168 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 256-bit memory bus, and uses a 14 nm design. It is made up of 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 the same performance. (explain)

Texel Rate

The Radeon RX 570 should be a little bit (approximately 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 the winner, 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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
