Radeon R7 M265 vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which comes with a GPU core clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 560 should theoretically be much superior to the Radeon R7 M265 in general. (explain)

Radeon RX 560		114688 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 82688 (258%)

Texel Rate

The Radeon RX 560 is a lot (approximately 332%) better at anisotropic filtering than the Radeon R7 M265. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 57800 (332%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 560 is the winner, and very much so. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 13000 (224%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
