Radeon HD 5750 1GB vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which has core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs 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 quite a bit 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 a lot (approximately 198%) faster with regards to texture 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

The Radeon RX 560 is quite a bit (about 68%) more effective at full screen anti-aliasing than the Radeon HD 5750 1GB, and also should be capable of handling higher screen resolutions better. (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: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
