I would love to see the results of a 3D chip with a powerful iGPU. Not sure if it would work, but if it is possible, why is AMD not doing it? Would it cannibalise 100-200 eur GPU (they are already nonexistent anyway).
There is very little demand for a powerful iGPU desktop chip, so the ones that exist are derivatives of laptop chips and thus monolithic. So far there has not been a stacked cache monolithic die chip.
It's easy to say there no demand for something that doesn't exist. Sales are zero.
Igpu is not apu
The laptop based desktop chips exist they are literally a thing and have been for a while. Both AMD and Intel have not seen high demand for those. Also even if that wasn't the case, your argument is not really an argument at all since it can just be used to justify literally anything that hasn't been tried.
lol they aren't powerful, in this universe or any other
I do think this will change quickly if Qualcomm's ARM chips are as fast as the M2 Max like they claim. And there's reason to believe it, as they've bought/hired Apple's head of processor development.
Considering the M2 Max GPU is roughly equivalent to a 3080 mobile or a desktop 3060ti at significantly better efficiency, I think the demand for monolithic could explode practically overnight.
Assuming some x86 to ARM translation gets most things running.
Maybe Qualcomm would do so in the future, but as things stand now, it's not the case.
The iGPU in the Snapdragon X Elite is on the same ballpark as the regular M2. Not the Pro or Max variant.
In 3DMARK wildlife extreme, the X Elite GPU is 50% faster than Radeon 780M.

Still, that's nowhere near 3080 tier.
Qualcomm still needs to work on their Windows GPU drivers. Currently the only API the X Elite supports is DirectX12.
Some speculate that Qualcomm will eventually create Windows Vulkan driver for Adreno. And then use DXVK to support older DirectX versions, and use Zink to support OpenGL.
They already have a vulkan driver. The 3dmark runs were on vulkan
Are you talking about the Snapdragon X Elite? Sure, their mobile chips do have Vulkan drivers.
If you go to the Snapdragon X Elite Product Brief, you can see the only supported API is DX12.
The 3dmark figures that you quoted were run using vulkan. X elite has working vulkan drivers on windows
There was little demand. Things change.
We're still very far from that. Even mobile phones don't stack GPU, they only stack RAM and NAND. RAM and cache are far simpler to stack since they are simple things in nature. While GPU is unbelievably complicated compared to those 2. Maybe Intel's tile / AMD's chiplet system is closer to what we want, but it's still not as good as stacking.
AMD is planning on the mi300 technically but that's for enterprise and will cost tens of thousands.
