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 clocked the core frequency at 1100 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this particular model. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

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

Theoretically speaking, the Radeon RX 550 should perform a small bit faster than the Radeon RX 460 2GB overall. (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 much (about 73%) better at 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 lots of anti-aliasing is important to you, then the Radeon RX 550 is the winner, though not by far. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video 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 most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
