The PCI Express 6.0 specification is announced and due to arrive in 2022, with products to follow - turnagethadfice
Time marches on, and so does the PCI Expressage standard. The PCI SIG pre-announced PCI Express 6.0 on Tuesday, scheduled to bring I/O transfer rates of 256 gigabytes per second (GBps) in a some years.
For I/O fans, the PCI Express standard is snarled at the intersection of the former, here and future. To a lesser degree a month agone, at Computex in Taipei, AMD declared that the X570 chipset and Ryzen 3800X would be the first to keep going PCI Express 4.0 and its 64GBps interface. The majority of PCs are stuck on PCI Express 3.0, with information transfers of 32GBps. (Here's everything you require to know just about PCI Express 4.0.)
A few days subsequently, the PCI Express 5.0 specification was published, support up to 128GBps. It's overly early to tell off when products supporting that specification will arrive, though most likely they'll arrive in 2020.
The PCI SIG's pre-announcement of the PCI Expressage 6.0 standard includes a target date stamp of 2021 for the release of the specification. True products based upon that spec would be expected to come along a year more or less after.
The PCI SIG is racing along at a rate passably akin to Moore's Practice of law for CPUs. The SIG is concerned with doubling I/O bandwidth every three years, meaning the SIG's PCI Express standard has to keep up with and even exceed that. It took more than six years between PCI Fast 3.0 (2010) and PCI State 4.0 (late 2017), but the SIG in real time appears to be cover on track.
PCI SIG Technically, PCI Carry 6.0 supports a 64 gigatransfer raw rate crosswise a x16 configuration. It utilizes PAM-4 encoding, leveraging the existing 56G PAM-4 already in the manufacture. It includes low-set-latency forward error correction, too. More importantly, it's also backward-well-matched with former PCIe specifications, A the preceding specs have been, excessively.
In all, PCI Express 6.0 isn't something you'll need to care about, or covet, for a a couple of years. But the groundwork is being arranged.
