Official PCIe 8.0 draft aims for 1 TB/s data rate
Final specs due for release in 2028, so don't hold your breath for the hardware
An official draft of the PCI Express (PCIe) 8.0 specificationis out, targeting a blistering 1 terabyte per secondwhen the kit finally hits the streets.
The PCI Special Interest Group (PCI-SIG) has released draft0.5 of the version 8.0 standard, incorporating feedback received from memberorganizations after the releaseof draft 0.3 last year.
With an expected raw bit rate of 256 gigatransfers persecond (GT/s) and up to 1 TB/s bi-directionally across a 16-lane configuration, PCIe8.0 is set to deliver another doubling of bandwidth over its predecessor, something the engineers weren't sure could be done.
PCI-SIG says the completed PCIe 8.0 specification remainon track for full release by 2028, though buyers may need to wait longer for any super-fast devices such as solid-state drives (SSDs).
Micron, for example, announced mass production of what it claimsis the firstPCIe 6.0...
