The CPU bottleneck would be resolved by the Pentium Gold 8505, but it still has the same 9 lanes of PCIe 3.0.

I only came across the existence of this CPU a few months ago, it is Nearly the same price class as a N100, but has a full Alder Lake P-Core in addition. It is a shame it seems to only be available in six port routers, then again, that is probably a pretty optimal application for it.
