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.
