Radeon RX 550 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which has a core clock speed of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It features 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
Radeon RX 5500		150 Watts
	Difference: 100 Watts (200%)

Memory Bandwidth

Performance-wise, the Radeon RX 5500 should in theory be quite a bit superior to the Radeon RX 550 in general. (explain)

Radeon RX 5500		229376 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 114688 (100%)

Texel Rate

The Radeon RX 5500 should be a lot (more or less 318%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 111760 (318%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5500 is the winner, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 35840 (204%)

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 megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
