Radeon HD 5750 1GB vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which has a clock frequency of 1175 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 14 nm design. It is made up of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Radeon RX 560		80 Watts
Radeon HD 5750 1GB		86 Watts
	Difference: 6 Watts (8%)

Memory Bandwidth

Performance-wise, the Radeon RX 560 should in theory be a lot better than the Radeon HD 5750 1GB overall. (explain)

Radeon RX 560		114688 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 41088 (56%)

Texel Rate

The Radeon RX 560 should be much (more or less 198%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 50000 (198%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 560 is the winner, by far. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 7600 (68%)

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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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