Radeon R9 M365X vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which features core clock speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 is 59% faster than the Radeon R9 M365X overall, because of its higher data rate. (explain)

Radeon RX 550		114688 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 42688 (59%)

Texel Rate

The Radeon R9 M365X is a little bit (approximately 5%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 1800 (5%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 550 is superior to the Radeon R9 M365X, not by a very large margin though. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 2800 (19%)

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 data (counted in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
