Radeon R9 M375X vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which features GPU core speed of 1175 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 560 should theoretically be much better than the Radeon R9 M375X in general. (explain)

Radeon RX 560		114688 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 42688 (59%)

Texel Rate

The Radeon RX 560 should be quite a bit (more or less 85%) more effective at AF than the Radeon R9 M375X. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 34600 (85%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 560 is superior to the Radeon R9 M375X, though only just barely. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R9 M375X		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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, 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 maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
