Memory Bandwidth

As far as performance goes, the Radeon RX 560 should in theory be quite a bit superior to the Radeon HD 5450 in general. (explain)

Radeon RX 560		114688 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 101888 (796%)

Texel Rate

The Radeon RX 560 should be quite a bit (approximately 1346%) faster with regards to texture filtering than the Radeon HD 5450. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 70000 (1346%)

Pixel Rate

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

Radeon RX 560		18800 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 16200 (623%)

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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
