Radeon RX 460 2GB vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which features clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 RAM. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
Radeon RX 460 2GB		75 Watts
	Difference: 25 Watts (50%)

Memory Bandwidth

As far as performance goes, the Radeon RX 550 should in theory be a bit better than the Radeon RX 460 2GB in general. (explain)

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

Texel Rate

The Radeon RX 460 2GB should be quite a bit (more or less 73%) faster with regards to anisotropic filtering than the Radeon RX 550. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 25840 (73%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 550 is superior to the Radeon RX 460 2GB, but it probably won't make a huge difference. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon RX 460 2GB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number 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 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
