Radeon R9 M380 vs Radeon RX 550

Intro

Compare that to the Radeon RX 550, which features GPU core speed of 1100 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 550 should in theory be a small bit better than the Radeon R9 M380 in general. (explain)

Radeon RX 550		114688 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 18688 (19%)

Texel Rate

The Radeon R9 M380 should be a little bit (more or less 14%) more effective at AF than the Radeon RX 550. (explain)

Radeon R9 M380		40000 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 4800 (14%)

Pixel Rate

The Radeon RX 550 is a little bit (approximately 10%) better at anti-aliasing than the Radeon R9 M380, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 1600 (10%)

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 data (in units of MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 maximum fill rate.
