Interesting, Acer is currently working on a Predator Helios 500 laptop, that by itself is nothing new, however, the product is listed with a Ryzen 7 2700 and RX Vega 56 graphics unit.

I'm not quite sure how power friendly the setup would be with an AMD Ryzen 7 2700 8-core processor and Radeon RX Vega 56 graphics. The inclusion of the energy-hungry Radeon RX Vega 56 is really the surprising element here. While it's likely down-tuned, there currently are no specification listed. 

Acer's model Predator Helios 500 notebooks will not just be AMD Ryzen/Radeon based as they will offer an Intel i9-8950HK + NVIDIA GTX 1070 combo as well. The AMD Part will get Freesync compatibility and Nvidia a GSync version. The Helios 500 laptops will all get a FullHD 144Hz panel. Pricing is to be announced.
