It's been confirmed how it looks like for the cooling https://news.ycombinator.com/item?id=35286544#35289558

Thing is laptops don't really have a certification standard with the only exception being amd advantage which is for all amd gaming laptops and Intel evo which is for Intel ultrabooks. At least it's not as compared to someone's so called "standard" i.e If anyone thought this works I wonder what they are smoking. Although this post was from the same person that wanted a bga socket with interposed even though I don't think that's the best long term solution for bga connections.

There was actually a reason why for that. It reaches its max clocks faster than it can use the wattage. Remember that computerbase.de image I shared?

This looks interesting. https://twitter.com/JarrodsTech/status/1628922420898992129?s=20

I don't remember a 16 inch laptop that fits a 608mm+ die and 384 bit bus. There was only 1 laptop that did and it had to make so much sacrifices. That was the studiobook one. Even so, look at this thing.

Unfortunately it's a pipe dream due to die size. Its double of ad 103's. Mobo's would have to ditch ton of things to fit that along with the cpu. And MXM gpus rn are small. And horizontal space is a premium. 99% 4090 would only go into workstations. And even so, the quadro A series is for that.

Basically the 4070 and 4060 are not wattage constrained. but frequency constrained.

"With the RTX 4070 laptop GPU, this is 2,400 MHz, which are in 11 of the 14 games with an average consumption of well below 115 watts. With the RTX 4060 laptop GPU it is 2.610/2.625 MHz – in 10 of 14 games this clock is already reached at an average of less than 115 watts. This behavior is fundamentally different from that of the two larger GPUs, which operated at over 150 watts in each game in the test, because they were able to convert the additional electrical budget available via Dynamic Boost into even higher clock rates. The maximum possible clock (2.355 MHz for the 4090 and 2.520 MHz for the 4080) was reached only in Far Cry 6. So the clock was almost never the limit, but with the smaller variants this is the rule."

4060 mobile has been tested.

So someone revealed that test mobo's for mobile cpus use interposers. Which are basically socketable bga. same for the chipset. Before some goes "WHY IS THIS NOT IN LAPTOPS?!" It's because these type of sockets are very expensive. like 1k usd+ expensive. Not only that. Interposers can wear. They are not really made for long term use just for testing.

Thats basically the concept of the asus flow series. Though for thr desktop chip thing. They would have to be modified anyway to support the certain laptop technologies. Including things like optimus. Desktop gpus don't really support that in their drivers.

is this for all with nvidia mobile GPUs or no.

Fromer is cuz gddr6x is too innefienct and hungry for power. latter is cuz of size. mobo has to be large for that bit bus. the studiobook one iirc is the only laptop i've seen with a 102 die but it comes with consequenses. Laptops do not have a standard at all. the only standard that there is are where components are placed. battery at the front, heatsink at the rear below the back side of the keyboard. and ram/storage in the middle. the x170 is kinda an exception. as the heatsink components extend from the middle to the top. The other thing is that a chip would have to be one where it peforms more efficiently under high power but struggles weakly under low power. The equivalent to that car wise is a rotary. Low rpm, it sucks, it needs high rpms.

Also should've mentioned that the main issue is pcb size. The studiobook one for example had a big mobo because of size for traces. Like how much is a bit bigger and thicker. Since with 16:10 coming along that is starting to change again. Another factor was the deisgn the x170/gt77/76 arent only wider, but their longer. Like 13 inches long. There's also antoher factor. WIth HX being a glorified desktop cpu in bga form. There would really need to be a very specific case where the board would go for a desktop cpu rather than an HX one.
