Radeon RX 570 vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which uses a 12 nm design. AMD has clocked the core frequency at 1469 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this particular model. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

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

Pixel Rate

The Radeon RX 590 should be much (approximately 26%) better at anti-aliasing than the Radeon RX 570, and able to handle higher screen resolutions more effectively. (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 max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at 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 worked out by multiplying the amount of Render Output Units 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
