Radeon RX 460 vs Radeon RX 550

Intro

The Radeon RX 460 comes with core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Compare those specs to the Radeon RX 550, which has core clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Consumption (Max TDP)

Radeon RX 550 50 Watts
Radeon RX 460 75 Watts
Difference: 25 Watts (50%)

Memory Bandwidth

Theoretically, the Radeon RX 550 should perform a little bit faster than the Radeon RX 460 overall. (explain)

Radeon RX 550 114688 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 2688 (2%)

Texel Rate

The Radeon RX 460 should be a lot (about 73%) faster with regards to texture filtering than the Radeon RX 550. (explain)

Radeon RX 460 61040 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 25840 (73%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 550 is superior to the Radeon RX 460, not by a very large margin though. (explain)

Radeon RX 550 17600 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 160 (1%)

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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that are processed per 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
