Radeon R9 M375 vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which comes with GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 560 will be 226% faster than the Radeon R9 M375 in general, because of its higher bandwidth. (explain)

Radeon RX 560		114688 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 79488 (226%)

Texel Rate

The Radeon RX 560 should be a lot (more or less 85%) better at AF than the Radeon R9 M375. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 34600 (85%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 560 is a better choice, but not by far. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 2560 (16%)

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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
