AMD Radeon RX 570 (Laptop) vs AMD Radeon RX 570 (Desktop) vs AMD Radeon RX 540X
AMD Radeon RX 570 (Laptop)► remove
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)► remove
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 540X► remove
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.
