Radeon HD 5750 512MB vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core frequency at 1175 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 16 ROPs.

Radeon RX 560		80 Watts
Radeon HD 5750 512MB		86 Watts
	Difference: 6 Watts (8%)

Memory Bandwidth

In theory, the Radeon RX 560 should be 56% quicker than the Radeon HD 5750 512MB overall, because of its higher bandwidth. (explain)

Radeon RX 560		114688 MB/sec
Radeon HD 5750 512MB		73600 MB/sec
	Difference: 41088 (56%)

Texel Rate

The Radeon RX 560 is much (approximately 198%) faster with regards to anisotropic filtering than the Radeon HD 5750 512MB. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 50000 (198%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 560 is superior to the Radeon HD 5750 512MB, by far. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon HD 5750 512MB		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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
