The PCI-SIG announced today the PCI Express 8.0 specification due out in 2028 will double the data of the PCI Express 7.0 specification, taking it to 256 GT/s.

PCI Express 8.0 is tracking to be published in 2028 and will top out at 256 GT/s for its raw bit rate and up to 1 TB/s bi-directionally in an x16 configuration. PCIe 8.0 is also evaluating new connector technology while still PCIe 8.0 will maintain backwards compatibility with prior PCI Express generations. New techniques continue to be worked on for reducing power consumption for PCI Express.

More early details around PCI Express 8.0 can be found via [1]the PCI-SIG press release .

"Insofar as I may be heard by anything, which may or may not care
what I say, I ask, if it matters, that you be forgiven for anything
you may have done or failed to do which requires forgiveness.
Conversely, if not forgiveness but something else may be required to
insure any possible benefit for which you may be eligible after the
destruction of your body, I ask that this, whatever it may be,
be granted or withheld, as the case may be, in such a manner as to
insure your receiving said benefit. I ask this in my capacity as
your elected intermediary between yourself and that which may not be
yourself, but which may have an interest in the matter of your
receiving as much as it is possible for you to receive of this
thing, and which may in some way be influenced by this ceremony. Amen."
