AMD Radeon RX 560 (Laptop) vs AMD Radeon RX 540X vs AMD Radeon RX 570 (Laptop)

AMD Radeon RX 560 (Laptop)

The AMD Radeon RX 560 for laptops (RX 560M) is a mid-range Polaris 11 / 21 gaming graphics card for laptops. It was first shown at CES 2017 in the Lenovo Legion Y520 as the "AMD RX 560M" with up to 4 GB GDDR5 VRAM. As the desktop RX 560 it can be based on the Polaris 21 and 11 chip (RX 560 and RX 460) with 986 or 1024 shaders. The performance should be similar to the desktop variants, with slightly reduced clock speeds.

AMD Radeon RX 540X

The AMD Radeon RX 540X is mobile mid-range graphics card for laptops based on the Polaris 12 chip (most likely). It is manufactured in an improved 14 nm FinFET process and technically similar to the older Radeon RX 540. The only difference so far is a 4% higher theoretical peak performance (1.25 versus 1.2 TFLOPS according to AMD). Compared to Nvidia graphics cards, the gaming performance should be between the GeForce GTX 950M and GTX 960M.

The similar named Radeon 540X (without RX) offers a smaller memory bus and therefore also a slightly reduced performance.

The features of the Radeon RX 540X are identical to the faster RX 460 and all other Polaris chips. See more details on the Polaris architecture here.

The power envelope of the faster Radeon Pro 460 is rated at 35 Watt according to the AMD blog post. Due to the slower specs, the Radeon RX 540 use slightly less.

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.
