Radeon RX 5600 XT vs Radeon RX 580

Intro

Compare all that to the Radeon RX 580, which features a core clock frequency of 1257 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and uses a 14 nm design. It is made up of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon RX 580		185 Watts
	Difference: 25 Watts (16%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT is 31% quicker than the Radeon RX 580 in general, because of its greater bandwidth. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 81920 (31%)

Texel Rate

The Radeon RX 5600 XT will be a small bit (more or less 9%) more effective at texture filtering than the Radeon RX 580. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 16992 (9%)

Pixel Rate

The Radeon RX 5600 XT is quite a bit (more or less 119%) more effective at anti-aliasing than the Radeon RX 580, and capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 47776 (119%)

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 max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of 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.
