Radeon HD 5830 vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which comes with a GPU core clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the Radeon RX 590 should perform much faster than the Radeon HD 5830 overall. (explain)

Radeon RX 590		262144 MB/sec
Radeon HD 5830		128000 MB/sec
	Difference: 134144 (105%)

Texel Rate

The Radeon RX 590 will be a lot (about 372%) better at anisotropic filtering than the Radeon HD 5830. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 166736 (372%)

Pixel Rate

The Radeon RX 590 will be quite a bit (more or less 267%) more effective at anti-aliasing than the Radeon HD 5830, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 590		47008 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 34208 (267%)

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 data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
