Radeon RX 5500 XT vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which makes use of a 14 nm design. AMD has set the core speed at 1168 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this particular model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

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 memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon RX 5500 XT is a small bit (about 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 will be quite a bit (more or less 47%) more effective at AA than the Radeon RX 570, and also will be capable of handling higher 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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
