Having wrapped up their work on the PCI-Express 5.0 specification earlier this year, the PCI-SIG wasted no time in getting to work on the next version of the specification, PCIe 6.0. That specification, which is expected to be finished in 2021, will once again double PCIe’s bandwidth to 64 GigaTransfers/second – or roughly 128GB/sec (each direction) for a x16 slot – thanks to some high-end encoding technologies like PAM4.

At the time that PCIe 6.0 was first announced, the group was just beginning work on the specification. And now a few scant months later, the group has released a brief update, announcing that they have already completed version 0.3 of the new spec.

The announcement itself is light on technical details, as the design goals and major underlying technologies for PCIe 6.0 were announced at the very start of the project. However the organization is keen to ensure that PCIe development continues moving at a steady pace, to avoid repeating the long gap between 3.0 and 4.0.

And the group’s members will certainly be busy. Even with the 0.3 specification in hand, it’s going to be nearly another two years before the specification is done, reflecting on the fact that there’s a lot of work left to be done to solve the technical challenges in developing PCIe 6.0, and bringing new signaling standards into the specification while maintaining backwards compatibility.

    You are among a dwindling minority of people that assign that importance to quality. In Anandtech's comments alone, the clamor of people citing that as a factor has declined drastically and this is a community of users disconnected almost entirely from the mainstream population. But hey, it's fine with me. I am not saying your concerns are invalid. I don't stream or buy discs since watching media isn't something I do for amusement so I can't speak for the competitiveness eitehr way.

    i know quite a few people that prefer a disc in their hand over streaming, for the same reasons, A/V quality.

    Don't forget poor Teddy RamBus. RD-RAM 4evah!

    Yeah, RDRAM was going to save the world. Now you can't find a continuity module to save your life.

    I'm very curious to see how PCIe 5.0 and above impact external GPU setups. I'm running a GTX 1060 through my eGPU right now at PCIe 3.0 x4, and the performance impact is substantial (around a 35-40% drop when running on my laptop screen). Quadrupling that bandwidth could make a world of difference, especially for people who aren't running external monitors.
