Radeon R9 M380 vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which has a core clock speed of 1100 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 550 should in theory be a little bit superior to 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 is a little bit (about 14%) more effective at texture filtering 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 just a bit (about 10%) better at full screen anti-aliasing than the Radeon R9 M380, and also should be able to handle higher resolutions better. (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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
