Radeon RX 570 vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which comes with GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 Texture Address Units, and 32 Raster Operation Units.

Radeon RX 570		149504 Mtexels/sec
	Difference: 62032 (41%)

Pixel Rate

The Radeon RX 590 is much (more or less 26%) more effective at FSAA than the Radeon RX 570, and capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 590		47008 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 9632 (26%)

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 data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of 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 clock 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 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 calculated by multiplying the number of Render Output Units 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
