Radeon R9 M380 vs Radeon RX 560

Intro

The Radeon R9 M380 uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Compare those specs to the Radeon RX 560, which uses a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 RAM is set to run at a speed of 7000 MHz on this card. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

The Radeon RX 560, in theory, should perform a small 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 a lot (approximately 88%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)

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

Pixel Rate

The Radeon RX 560 should be a bit (more or less 18%) better at anti-aliasing than the Radeon R9 M380, and also will be able to handle higher screen resolutions more effectively. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
