From HW perspective, i have now Ryzen 2200 APU, its 65W and has Vega 8 GPU too and even with 3000 DDR4 MHz memory, 1080p gaming is problematic even on low details.. And now they would have slower apu with 5 hours of battery life for 1080p, its nonsense.
All previous AMD low power APUs was complete fail, i dont believe that they really have working prototype, these FPS numbers there are not proofs at all.. otherwise they would show as something better like running Afterburner OSD and hand on video.
And their forum section on their site - you cant even create a post..
