Radeon RX 550 vs Radeon RX 5500

Intro

Compare those specs to the Radeon RX 5500, which has a GPU core clock speed of 1670 MHz, and 4096 MB of GDDR6 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 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

Theoretically speaking, the Radeon RX 5500 is 100% faster than the Radeon RX 550 in general, because of its greater data rate. (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%) faster with regards to 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 resolution is important to you, then the Radeon RX 5500 is a better choice, by far. (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 data (counted in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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