PCIe 6.0 spec version 0.5 released to members

The PCI Special Interest Group has announced another milestone in the development of PCie 6.0. Last October we heard that the PCIe 6.0 v0.3 spec was ready for members, now it has been elevated to version 0.5. The newer version is said to incorporate changes reflecting significant member feedback and marks "momentous progress," according to PCI-SIG, an organisation which doesn't usually indulge in overstatement.

While it took a considerable seven years from the introduction of PCIe 3.0 (2010) to the PCIe 4.0 spec landed, the special interest group has found new vigour and its forward charted progress is exponential. As charted previously, the bandwidth delivered by full versions number updates to the PCIe interface specs should double every three years. The PCI-SIG asserts that it is actually ahead of that curve at the time of writing and aims for things to stay that way.

Moving from v0.3 (concept) to v0.5 (first draft), is a well practised step for the PCI-SIG and it is expected that we will see v0.7 (complete draft) next, followed by the v0.9 (final draft) which goes on to become v1.0 (final release) after internal review by member companies. Typically v0.5 "has a complete set of architectural requirements and must fully address the goals set out in the 0.3 draft."

The last chance to add functionality to the spec will be now, ahead of the publishing of v0.7. However, companies will now start developing test silicon with the 'first draft' in hand. PCIe 6.0 will be a main theme of the presentations and discussions at the PCI-SIG Developers Conference 2020, from 3rd - 4th June.

So the question is whether this means that motherboards are likely to go from 4.0 to 6.0, skipping 5.0 due to this.

Doubt it… but then it's a possibility
Its a shame really that the graph is based on there release spec not the actual to the consumer, given its 2020 now and PCIe5 has yet to appear given the graph is like nailing it to 2019 where really only PCie4 hit Q3 2019 so its looking like 18 months lag behind the chart so Pcie6 looks destined for Q3/4 of 2022 so probably not take off for consumers until 2023.

I can't see 6 being implemented anytime this decade on consumer boards, 4-5 is a fairly straightforward change as 5 is basically a tweaked version of 4 (it extends 4), whereas 6 changes things pretty drastically (new signalling, new error correction, etc).
“the special interest group has found new vigour and its forward charted progress”

its about damn time the snails move faster… this group are much to SLOW with progress.
