Radeon RX 5500 vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which features core clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
Radeon RX 590		175 Watts
	Difference: 25 Watts (17%)

Memory Bandwidth

In theory, the Radeon RX 590 should be a little bit faster than the Radeon RX 5500 in general. (explain)

Radeon RX 590		262144 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 590 should be quite a bit (more or less 44%) more effective at texture filtering than the Radeon RX 5500. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 64576 (44%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5500 is the winner, not by a very large margin though. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 6432 (14%)

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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
