If you intended to install a dGPU in a desktop, why would you choose APU instead of a normal Ryzen CPU? Especially since APUs lag behind. In laptops, it's done for efficiency. Not as big a deal in a desktop. It's good that it offers more lanes but I'm not convinced they're going to be used for dGPUs.
An APU is useful in a desktop for various people who might not see the need in getting a standard CPU only.
The 4000 series APU's are comparable to their desktop counterparts, AND they come with an iGP. (which seem quite potent).
Think of all in one solutions. but for desktops.
Apart from that, not using 5700M, 2070 and above in laptops just because of 8 PCIe lanes is not a good reason - and also, I don't think its the ACTUAL reason.
For example, the DELL G5 15 SE is the ONLY laptop on the market to come with 4800H and 5600M... but despite the fact AMD also has 5700M (both 5600M and 5700M are highly efficient and powerful GPU's and comparable if not better than NV counterparts), no other OEM's will be using them - but DELL's cooling implementation is not really good to begin with (its not even allowing either 4800H or 5600M to reach their maximum potentials - whereas other laptop chases do).
Most Zen 2 laptops aren't being paired with anything above 2060... and I doubt the lanes is the reason why.
If they would put up a 'limit'... why not do it with 5700M and 2070 instead?
There's a much larger performance loss the higher above that you go and an unnecessary increase in power consumption... not to mention cost.
But then again, other OEM's don't really care and they still use RTX 2070, 2080 and 2080ti in laptops.
