Radeon R9 M380 vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular model. It features 1024 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 560 will be 19% faster than the Radeon R9 M380 overall, due to its higher data rate. (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%) better 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 a better choice, though only just barely. (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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
