PAM4 requires ultra-low loss materials (Megtron 6 or similar) and shorter trace lengths. Mainstream consumer motherboards may struggle to implement full x16 Gen6 slots without expensive retimers. pci express base specification revision 60 pdf
While PAM-4 doubles the bandwidth, it introduces new challenges. With four voltage levels, the separation between signal states is smaller than in NRZ, making the signal more susceptible to noise. Consequently, PCIe 6.0 requires more robust error correction mechanisms. Individual copies are available for purchase by non-members

Summary of PCIe 6.0 Performance PCIe Generation Gigatransfers per Second (GT/s) x16 Bandwidth (Bidirectional) Signaling Type 64 GT/s 256 GB/s PAM4 While PAM-4 doubles the bandwidth, it introduces new
However, achieving 64 GT/s over copper traces on a motherboard is not trivial. This required a radical shift in how PCIe encodes data.
