AMD Radeon RX 570 (Laptop) vs AMD Radeon RX 570 (Desktop) vs AMD Radeon RX 590 (Desktop)

AMD Radeon RX 570 (Laptop)

The AMD Radeon RX 570 for laptops (RX 570M) is a mid-range Polaris 10 gaming graphics card for laptops. It was first shown at CES 2017 in the Samsung Odyssey gaming notebook as an alternative to the GeForce GTX 1070. According to preliminary specifications from Samsung, the supposed RX 570M will ship in 4 GB and 8 GB GDDR5 VRAM variants. The RX 570M is expected to be a rebrand of the old RX 470 for laptops with the possibility of small bumps to the clock speed and/or shader count. As a result, gaming performance should be similar or slower to its desktop version. The Nvidia equivalent will likely be the GeForce GTX 1060 or GeForce 1050 Ti based on performance predictions.

AMD Radeon RX 570 (Desktop)

The AMD Radeon RX 570 is a mainstream graphics card for desktop PCs. It was announced in April 2017 and is based on the Polaris 20 chip. It is a refresh of the RX 470 and uses the same chip as the RX 580 (and 580X) with less shaders. The clock speeds are specified as 1,168 - 1,244 (Boost). The VRAM is connected by a 256 Bit bus and clocks at 1,750 MHz (effective 7,000 MHz) which leads to a 224 GB/s memory bandwidth.

At launch, the performance of the Radeon RX 570 was slightly below a Nvidia GeForce GTX 1060. Therefore, the GPU is best used for 1920x1080 and high detail settings for demanding games of 2019.

The TDP of the Radeon RX 570 is specified with 120 Watts by AMD, so a single 6-pin power connector is sufficient.

AMD Radeon RX 590 (Desktop)

The AMD Radeon RX 590 is a desktop graphics card positioned in the mid-range of 2018. It is manufactured in 12nm and offers 2,304 shader cores and 8 GB GDDR5 VRAM using a 256 Bit memory interface (8 GHz, 256 GB/s).

The RX590 uses the new Polaris 30 chip, which is a 12nm version of the Polaris 20 chip of the RX 580. Thanks to the improved process, the clock rates of the RX 590 can be higher at a similar power consumption. 

This leads to a 10 percent higher performance compared against the older Radeon RX 580 and therefore the RX 590 is faster than the GeForce GTX 1060. This means that the card is best suited for 1080p gaming in max. details (of 2018 games).

The power consumption is rated at 175 Watt and therefore 10 Watts below the Radeon RX 580 (185 Watt).
