The PCIe 6.0 technology this week achieved an important milestone as PCI-SIG released version 0.7 of the specification. The release of the new 'complete draft' specification indicates that the technology has been defined and its electrical specifications have been validated using test chips. Essentially, it means that PCIe 6.0 is ready and functional, so it is only a matter of time before it is finalized sometime in 2021.

PCIe 6.0 will increase data transfer rate to 64 GT/s per pin, up from 32 GT/s in case of PCIe 5.0 and 16 GT/s in case of PCIe 4.0. In a bid to increase data transfer rate and bandwidth, the new interface adopted pulse amplitude modulation with four levels (PAM4) signaling, which is also used for high-end networking technologies like InfiniBand as well as GDDR6X memory.

The release of the PCIe 6.0 spec version 0.7 is a particularly important one since after this release no new features can be added and electrical specifications of the technology have been validated using test chips. In fact, at this stage, various companies may have actual implementations of the new bus ready (but not necessarily announced).

PCIe 6.0 Specification Progress Now At Final Draft, Data Transfer Speeds As High As 128 GB/s
October 8, 2021

PCI-SIG revealed earlier this week that PCIe 6.0 specification has reached the Final Draft stages—an important and much-needed step that shows completion of the Gen 6 PCIe technology. Any current SoCs conformable with version 0.9 specs will now be accessible to the new 1.0 versions. The only uncertainty is what applications need to upgrade and prepare for the PCIe 6.0 technology.
PCIe 6.0 Standard Almost Finalized, Hits Bandwidth of Up To 128 GB/s
PCIe 6.0 is listed to increase data transfer rates to 64 GT/s per pin, which is an increase from PCIe 5.0 speeds of 32 GT/s. The new technology will remain backward compatible with any current existing hardware. PCIe will now be capable of data transfers of 128 Gb/s in all directions on the x16 interfacing.

The Final Draft version of PCIe 6.0 (version 0.9), allowed for members of the PCI-SIG to review the new standards for not only patents but also intellectual properties. From that point forward, no changes were permissible by PCI Express.
Manufacturers and developers utilizing PCIe Gen 6 version 1.0 had to create specific standards so that they could reach such high data transfer rates.

The only hurdles for developers now are both cost and concerns overpower. PAM-4 is an expensive endeavor when it comes to both size of the die and in power, which will cause manufacturers to reduce costs were accessible to conform to the newest PCIe 6.0 technology.
