Radeon RX 5500 XT vs Radeon RX 570

Intro

Compare all that to the Radeon RX 570, which comes with GPU core speed of 1168 MHz, and 4096 MB of GDDR5 memory running at 1750 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, 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 memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon RX 5500 XT is a 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 is much (approximately 47%) more effective at anti-aliasing than the Radeon RX 570, and also will be able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
