Radeon R9 M380 vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which has core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 560 should perform a bit faster than the Radeon R9 M380 in general. (explain)

Radeon RX 560		114688 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 18688 (19%)

Texel Rate

The Radeon RX 560 will be much (more or less 88%) more effective at texture filtering than the Radeon R9 M380. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 35200 (88%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 560 is the winner, but it probably won't make a huge difference. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 2800 (18%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
