I have the Alienware 16 Area-51 AA16250 with the 5090. The laptop is a damn near 400W laptop. That said? It's just shy of my RTX 4080 desktop at 4K and 1800P gaming, which is exactly where I expected it would land, based on the specs. Who knows? Maybe the drivers will age well. I know AMD ones do. They're weird like that. I remember running games like AC Valhalla on my 6900XT and getting between 67-80FPS at 3840x1440 ultrawide. Then, around the time 7000 series release, I was running up to 107FPS on the same Pc, same OS install, same game...you just have to wait around a couple years for AMDs to do well. It was the same for my Vega64 (supposed 1080 killer at release). At launch it was anything but. 2 years later it was virtually on par a 1080, which I also had around that time and had gotten for free at work. Back then I was using AC Origins as my return to game to compare off of.
