Not sure you'd get an optimal gaming laptop out of these, because I'd have to concur that mobile dGPUs simply can't burn the Wattage of their desktop cousins. Perhaps more of a CUDA workstation, but these aren't mass market items. I wonder just how many of these chips AMD is selling...
I got a Dragon Range Zen4 16-core variant as a mobile-on-desktop Mini-ITX board from Minisforum and it's a very reasonable µ-server in my case, but would also work rather well as a gaming rig.
They don't have X3D models available, which I might have grabbed, otherwise; I'm very happy with the 7950X3D desktop CPUs I also own.
In practical gaming the difference between those two isn't nearly as high as the reviews seem to indicate, some things like Flight Simulator (2020 and 2024) in VR just suck no matter what I throw at them (RTX 4090 included), most others are just good enough to enjoy with either one.
My main attraction was the price point (€500 for the mainboard including the 16-core Zen 4 CPU) and the fact that for a stationary system, it's rather low power and noise.
TDP can be configured somewhere between 100 and 35 Watts on that board, mine runs "unconstrained" and it will reach 100 Watts on Prime95 max-heat for the entire APU according to HWinfo, 130 Watts at the wall plug, yet a simple quiet 90mm fan will keep it cool and idle is between 20 and 30 Watts at the wall plug, much less than typical Zen desktop systems.
Perhaps their target is really more mobile workstations but once their successors are announced, they evidently sell at much more reasonable prices.
BTW: while the iGPU is weak in terms of 3D, it's really rather snappy for 2D and works like a charm in hybrid mode with older dGPUs. E.g. I was able to get 4k at 144Hz and HDR out of the iGPU pairing it with a GTX1080ti, which can't deliver anything beyond 60Hz at 4k on its own. And gaming performance didn't suffer nearly as much from that hybrid configuration as I'd have imagined.
