Radeon RX 5500 vs Radeon RX 580

Intro

Compare all of that to the Radeon RX 580, which makes use of a 14 nm design. AMD has set the core frequency at 1257 MHz. The GDDR5 RAM works at a speed of 2000 MHz on this model. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
Radeon RX 580		185 Watts
	Difference: 35 Watts (23%)

Memory Bandwidth

The Radeon RX 580 should theoretically perform a little bit faster than the Radeon RX 5500 overall. (explain)

Radeon RX 580		262144 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 580 should be much (more or less 23%) more effective at texture filtering than the Radeon RX 5500. (explain)

Radeon RX 580		181008 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 34048 (23%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5500 is a better choice, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 13216 (33%)

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 moved across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
