Radeon RX 460 2GB vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which makes use of a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this specific card. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

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

Texel Rate

The Radeon RX 460 2GB will be much (approximately 73%) faster with regards to texture 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 running with a high resolution is important to you, then the Radeon RX 550 is superior to the Radeon RX 460 2GB, though only just barely. (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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
