Radeon R9 M365X vs Radeon RX 550

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 550, in theory, should be a lot faster than the Radeon R9 M365X in general. (explain)

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

Texel Rate

The Radeon R9 M365X should be a little bit (about 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

The Radeon RX 550 should be just a bit (more or less 19%) better at anti-aliasing than the Radeon R9 M365X, and also capable of handling higher resolutions without slowing down too much. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock 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 maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
