Radeon R9 M380 vs Radeon RX 560

Intro

The Radeon R9 M380 makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon RX 560, which has a clock frequency of 1175 MHz and a GDDR5 memory speed of 7000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 14 nm design. It is made up of 1024 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 560 will be 19% faster than the Radeon R9 M380 overall, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 560 should be much (more or less 88%) more effective at 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 will be a small bit (more or less 18%) faster with regards to AA than the Radeon R9 M380, and also should be capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the 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 maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
