Radeon R9 M265X vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which comes with clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 560 should perform quite a bit faster than the Radeon R9 M265X overall. (explain)

Radeon RX 560		114688 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 42688 (59%)

Texel Rate

The Radeon RX 560 should be much (about 227%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 52200 (227%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 560 is superior to the Radeon R9 M265X, and very much so. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 9600 (104%)

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 largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
