PCI Express 7.0 launches with 512GB/s peak bandwidth

Published on

Today, the PCI-SIG presented PCI Express 7.0. The final specification is expected in 2025. The first PCIe 7.0 devices will go on sale sometime in 2027.
GSM Arena reports that version 5.0 of PCI Express (also called PCIe) was launched in 2017. However, it has just recently gained popularity. Both Intel’s LGA1700 socket and AMD’s AM5 socket support PCIe5.0. Only a handful of motherboards and CPUs that support PCIe 5.0 (such as Intel’s Adler Lake desktop processors) are currently available.
PCIe 6.0 will be released before that; it should be available in server parts by next year.

Hardware with exceptional bandwidth will soon be available. Each new generation of PCIe sees a double in speed. PCIe 5.0 components that you might soon have at your home are twice as fast than version 6.0 and version 7.0 will run four times faster.
This means that a single PCIe 7.0 bi-directional connection can transfer 32GB/s data. It is faster than a 16x connection using PCIe 3.0, which used to be the norm for GPUs. GSM Arena reports that the maximum bandwidth for a 16x connection can be reached at 512GB/s.
It will use PAM4 signals, which were introduced in version 6.0 of PCIe. This new generation will be focused on power efficiency, lower latency, and maintaining backwards compatibility to earlier standards.
