M4 Mac Mini - Thunderbolt PCIE Expansion - MacRumors Forums
2024年11月15日 · The Express 4m2 configures (by hardware or firmware) the PCIe switch of the Thunderbolt controller into four x1 slots. The Accelsior 4m2 has a PCIe switch to convert an x8 slot to four x4 slots. The Accelsior 4m2 is going to be more expensive because of the extra PCIe switch (plus the larger Helios Thunderbolt enclosure).
Thunderbolt 5 data transfer between two computers
2019年12月10日 · If Intel PCs are using PCIe 4.0 x4 Thunderbolt 5 host controllers (JHL9580, JHL9480), then they can't achieve 65 Gbps. You need PCIe 4.0 x8 or PCIe 3.0 x16 to achieve more than 63 Gbps. Or they need to integrate the Thunderbolt controller into the CPU like they did with IceLake and TigerLake or like Apple is doing with Apple Silicon.
