Radeon R9 M380 vs Radeon RX 560

Intro

The Radeon R9 M380 features core speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Compare all that to the Radeon RX 560, which features GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM running at 7000 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 560 should in theory be a small bit better than the Radeon R9 M380 overall. (explain)

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

Texel Rate

The Radeon RX 560 will be quite a bit (about 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 bit (approximately 18%) better at anti-aliasing than the Radeon R9 M380, and also capable of handling higher 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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.
