Having wrapped up their work on the PCI-Specific 5.Zero specification earlier this yr, the PCI-SIG wasted no time in attending to work on the subsequent model of the specification, PCIe 6.0. That specification, which is predicted to be completed in 2021, will as soon as once more double PCIe’s bandwidth to 64 GigaTransfers/second – or roughly 128GB/sec (every path) for a x16 slot – due to some high-end encoding applied sciences like PAM4.

On the time that PCIe 6.0 was first introduced, the group was simply starting work on the specification. And now a few scant months later, the group has launched a transient replace, asserting that they’ve already accomplished model 0.Three of the brand new spec.

The announcement itself is mild on technical particulars, because the design targets and main underlying applied sciences for PCIe 6.0 have been introduced on the very begin of the venture. Nevertheless the group is eager to make sure that PCIe improvement continues transferring at a regular tempo, to keep away from repeating the lengthy hole between 3.Zero and 4.0.

And the group’s members will definitely be busy. Even with the 0.Three specification in hand, it’s going to be practically one other two years earlier than the specification is finished, reflecting on the truth that there’s a lot of labor left to be achieved to unravel the technical challenges in growing PCIe 6.0, and bringing new signaling requirements into the specification whereas sustaining backwards compatibility.
