In June 2017, PCI-SIG announced the PCI Express 5.0 preliminary specification.<ref name="TR_pcie4" /> Bandwidth was expected to increase to 32{{nbsp}}GT/s, yielding 63{{nbsp}}GB/s<!-- 32 GT/s × 16 × 128/130 / 8 = 63,015,384,615 B/s --> in each direction in a 16-lane configuration. The draft spec was expected to be standardized in 2019.{{citation needed|date=July 2019}} Initially, {{Nowrap|25.0 GT/s}} was also considered for technical feasibility.

On 7 June 2017 at PCI-SIG DevCon, Synopsys recorded the first demonstration of PCI Express 5.0 at 32&nbsp;GT/s.<ref name="Syn50" />

On 31 May 2018, PLDA announced the availability of their XpressRICH5 PCIe 5.0 Controller IP based on draft 0.7 of the PCIe 5.0 specification on the same day.<ref name="n6z9y" /><ref name="9OVm8" />

On 10 December 2018, the PCI SIG released version 0.9 of the PCIe 5.0 specification to its members,<ref name="PCIe5r09" />
