Radeon HD 5830 vs Radeon RX 560

Intro

Compare that to the Radeon RX 560, which uses a 14 nm design. AMD has set the core speed at 1175 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this card. It features 1024 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
Radeon HD 5830		175 Watts
	Difference: 95 Watts (119%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 should perform a small bit faster than the Radeon RX 560 in general. (explain)

Radeon HD 5830		128000 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 13312 (12%)

Texel Rate

The Radeon RX 560 will be much (approximately 68%) better at AF than the Radeon HD 5830. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 30400 (68%)

Pixel Rate

If using lots of anti-aliasing 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 5830		12800 Mpixels/sec
	Difference: 6000 (47%)

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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
