What’s the advantage of Oculink over regular Thunderbolt/USB4 for eGPU ?

[p_l]

Essentially instead of running a not so trivial stack on both ends to handle USB4/TB4 virtual channel system over which you then tunnel PCIE L2 packets, it's straightforward, unmodified, PCIE connection with at most retimers/signal conditioners on both ends.

OTOH, it's only PCIE signal.

Reduced protocol overhead allowing for greater throughput. It is native PCIe.
