Radeon RX 5500 XT vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which features GPU core speed of 1168 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon RX 570		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon RX 5500 XT is a bit (about 1%) more effective at anisotropic filtering than the Radeon RX 570. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 1592 (1%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5500 XT is superior to the Radeon RX 570, by a large margin. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 17568 (47%)

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 (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
