“For 27 years, the PCI-SIG has continually delivered new versions of I/O standards that enable designers to accommodate the never-ending increases in bandwidth required for next generation systems, while preserving investments in prior generation interfaces and software,” famous Nathan Brookwood, analysis fellow at Insight 64. “Over that period, peak bandwidth has increased from 133 MB/second (for the first 32-bit parallel version) to 32 GB/second (for the V4.0 by16 serial version), a 240X improvement. Wow! The new PCIe 5.0 standard doubles that again to 64 GB/second. Wow2. We have come to take this increased performance for granted, but in reality, it takes a coordinated effort across many members of the PCI-SIG to execute these transitions so seamlessly.”
PCIe 5.0 Specification Highlights
- Delivers 32 GT/s uncooked bit fee and as much as 128 GB/s through x16 configuration
- Leverages and provides to the PCIe 4.Zero specification and its help for increased speeds through prolonged tags and credit
- Implements electrical adjustments to enhance sign integrity and mechanical efficiency of connectors
- Includes new backwards appropriate CEM connector focused for add-in playing cards
- Maintains backwards compatibility with PCIe 4.0, 3.x, 2.x and 1.x
The new specification will increase efficiency within the high-performance markets together with synthetic intelligence, machine studying, gaming, visible computing, storage and networking.
“AMD congratulates PCI-SIG on the release of the PCI Express 5.0 specification to the industry and the future 2x increase in performance it is expected to deliver. We expect to bring our first PCIe 4.0 specification CPUs to market this year and look forward to meeting the future bandwidth demands of end-users with PCIe 5.0 technology,” stated Gerry Talbot, AMD Corporate Fellow, Technology & Engineering Group.
“PCI Express 5.0 technology will advance graphics and high-performance computing by doubling its bandwidth to approaching 64 GB/s while maintaining socket compatibility with prior versions of the PCIe specification. We are proud to be part of the PCI-SIG team and look forward to the innovation that will be sparked by this next evolution,” stated Michael Diamond, senior director of strategic partnerships at NVIDIA and member of the PCI-SIG board of administrators, NVIDIA.
“Intel believes that open standards foster platform innovation, create healthy ecosystems, and accelerate market growth. As a founding promoter of PCI Express architecture, we fully support the newly-released PCIe 5.0 specification, and look forward to continuing the PCI Express specification tradition of high-performance, multi-platform, open interconnect,” stated Dr. Debendra Das Sharma, Intel Fellow and Director of I/O Technology & Standards, Member of PCI-SIG Board of Directors, Intel Corporation.
