Radeon RX 570 vs Radeon RX 590

Intro

The Radeon RX 570 has core speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Compare that to the Radeon RX 590, which features a core clock frequency of 1469 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit bus, and makes use of a 12 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 570 150 Watts
Radeon RX 590 175 Watts
Difference: 25 Watts (17%)

Memory Bandwidth

The Radeon RX 590 should in theory be a little bit faster than the Radeon RX 570 in general. (explain)

Radeon RX 590 262144 MB/sec
Radeon RX 570 229376 MB/sec
Difference: 32768 (14%)

Texel Rate

The Radeon RX 590 will be a lot (more or less 41%) more effective at texture filtering than the Radeon RX 570. (explain)

Radeon RX 590 211536 Mtexels/sec
Radeon RX 570 149504 Mtexels/sec
Difference: 62032 (41%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 590 is the winner, and very much so. (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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
