Radeon RX 5500 XT vs Radeon RX 570

Intro

Compare all that to the Radeon RX 570, which features core clock speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 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 exactly the same bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon RX 5500 XT is a little bit (approximately 1%) faster with regards to 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

The Radeon RX 5500 XT is quite a bit (about 47%) better at AA than the Radeon RX 570, and also capable of handling higher screen resolutions better. (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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen 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 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
