Obviously in terms of the overall laptop design (cooling and thermal insulation or component placement for comfort), but for the APU itself, it's just that the firmware (included in the BIOS/UEFI) tells it to run at whatever cTDP setting is required - range of 10 - 25W is available for the 4000 U-series.
This generation should bury water-cooling, and 15W should allow even passive cooling in thin designs. I'd risk someone has the gumption to slap one of these in a phone. Intel has to be squirming in their chairs right now.
You need to be under 10W for passive cooling in a small and crowded compartment such as a laptop. Phones have 5W TDP. 15W is perfect for a laptop, I find 45W a lot and cause overheating like my 4820HQ reaching 90C.
These are very nice products from AMD and I am pretty sure they will sell and raise AMDs image in the notebook market. Still, we need to see where they stand with these products because their handicap on mobile was much bigger than in desktop and mobile is a different market where efficiency is paramount. H series will sell well with gamers, maybe not being the definitive choice for gamers (lower max boost speeds means lower gaming perf) but we need to see reviews. U series also is interesting but here it all depends if they can get the idle power consumption under control. Thin and light laptops are called like that for a reason. People buy them to use them during travel and battery life is paramount. Not threads, not even absolute performance, but battery life and small things like sleep battery drain, sleep on/off speed, things that AMD is not usually great with (not even Intel, but they did improve massively with Ice lake).
Intel high end mobile CPUs are capped at 4Ghz and do not reach 4.5Ghz, users at Tomshardware are reporting this issue. Let see if AMD manages to reach 4.2Ghz as they claim, if they do, they will also be faster in single threaded loads than i9 10th gen.
It's a real bugger that their product cycle aligns so poorly with AMD's products...
That said, they're still selling a Surface Book 2 with a GTX 1060 in it. Maybe they've been waiting to build the Surface Book 3 with a 4800U and an RX 5600M in it... we can dream, eh?

It makes sense. I suppose there's no real counterpart from AMD to nVidia dGPU on mobile. Yet.Gonemad - Tuesday, January 7, 2020 - link

My Firepro W7100 reaches 98C under regular use - doesn't even ramp the fan over 70%. Got the thing recycled - miracle it's still aliveyeeeeman - Tuesday, January 7, 2020 - link

Wow, a well reasoned and balanced comment! Someday in the distant future I dream these will outnumber the argumentative troll posts...oh who am I kidding lol

Now it's time for Microsoft to announce an upgraded Surface that sports the new Ryzen 7 4800U!Spunjji - Tuesday, January 7, 2020 - link
