Radeon R9 M385X vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which uses a 14 nm design. AMD has set the core speed at 1175 MHz. The GDDR5 memory is set to run at a frequency 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

As far as performance goes, the Radeon RX 560 should in theory be a bit superior to the Radeon R9 M385X in general. (explain)

Radeon RX 560		114688 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 18688 (19%)

Texel Rate

The Radeon RX 560 should be quite a bit (about 22%) better at texture filtering than the Radeon R9 M385X. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 13600 (22%)

Pixel Rate

The Radeon RX 560 will be just a bit (about 7%) better at FSAA than the Radeon R9 M385X, and capable of handling higher resolutions while still performing well. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 1200 (7%)

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 within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
