Then doubling every 3 years from there would get us on time to the speed that PCIe 6.0 achieves in 2021 - not the 4 years later interpretation they show starting from 1992 that relies on the work of outside groups that created their own specification to get around PCI-SIG - providing we ignore the fact that PCIe 1.0 devices were available in 2004, a year after the specification release, and it's now 2021, two years after the PCIe 5.0 spec release, and we still don't have access to PCIe 5.0 devices. The graph should start with PCIe 1.0 in 2003. Starting the graph back at PCI in 1992 glosses over that PCI was too slow to begin with, which is why there was VESA local bus, and then AGP (Intel), and then finally the development of 3GIO by Intel, Dell, HP, and IBM, which was handed over to the PCI-SIG and renamed PCI-Express. Yojimbo - Tuesday, link I'm always bothered by seeing that PCI-SIG doubling graph.POST A COMMENT 103 Comments View All Comments Meanwhile, as the PCIe 6.0 specification reaches completion, we should finally begin seeing the first PCIe 5.0 devices show up in the enterprise market. Besides proving that they’re once again able to double the bandwidth of the ubiquitous bus, it will mean that they’ve been able to keep to their goal of a three-year cadence. Overall, the unabashedly nerdy standards group is excited about the 6.0 standard, comparing it in significance to the big jump from PCIe 2.0 to PCIe 3.0. All told we’re not expecting much different from 5.0 (in other words, only a slot or two on most consumer motherboards), but as each successive generation ratchets up the signaling rate, the signal integrity requirements have tightened. Once the updated electrical and protocol specs are approved, the group will be able to give some clearer guidance on the signal integrity requirements for PCIe 6.0. In the interim, the 0.9 specification is likely to be the most interesting from a technical perspective. After draft 0.9 lands, there will be a further two-month review for any final issues (primarily legal), and, assuming the standard clears that check, PCI-SIG will be able to issue the final, 1.0 version of the PCIe 6.0 specification. Ultimately, all of this is to say that PCIe 6.0 remains on track for its previously-scheduled 2021 release. Overall, the group’s rules call for a 30-day review period for the 0.71 draft, after which the group will be able to release the final draft 0.9 specification. The substance of this decision being that the group is essentially going to hold for another round of review and testing before finally clearing the spec to move on to the next major draft. In a bit of a departure from the usual workflow for the group, however, this upcoming draft will be 0.71, meaning that PCIe 6.0 will be remaining at draft 0.7x status for a little while longer. That draft will incorporate the all of the new protocol and electrical updates that have been approved for the spec since 0.7.
#Final draft 9 release date update
Since then, PCI-SIG has remained at work collecting feedback from its members, and is gearing up to release another draft update next month. The most recent draft version of the specification, 0.7, was released back in November. PCI-SIG has been working on PCIe 6.0 for a couple of years now, and in a brief update, confirmed that the group remains on track to release the final version of the specification by the end of this year. The star of the show, of course, was PCI Express 6.0, the upcoming update to the bus standard that will once again double its data transfer rate.
Following a minimum 30 day review process, the group will be able to publish the draft 0.9 version of the specficiation, putting them on schedule to release the final version of the spec this year.Īs part of their yearly developer conference, the PCI Special Interest Group (PCI-SIG) also held their annual press briefing today, offering an update on the state of the organization and its standards. Update 07/02: Albeit a couple of days later than expected, the PCI-SIG has announced this morning that the PCI Express draft 0.71 specification has been released for member review.
