Radeon RX 550 vs Radeon RX 5500

Intro

The Radeon RX 550 uses a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this model. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Compare those specs to the Radeon RX 5500, which makes use of a 7 nm design. AMD has clocked the core frequency at 1670 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this specific card. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

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 should perform quite a bit faster than 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%) 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 using a high screen 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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its 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 core 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
