PCIe 6.0 standard specification officially unveiled

According to the latest report, the PCI-SIG organization officially released the PCIe 6.0 standard, which doubles the bandwidth again compared with PCIe 5.0, reaching 64 GT/s.

Since the release of the PCIe 2.0 standard, each generation has doubled the bandwidth of the previous generation, increasing exponentially. PCIe 6.0 × 16 lanes have a bandwidth of 256 GB/s and lower latency than the previous generation.

Al Yanes, Chairman, and President of the PCI-SIG said he is pleased to be able to introduce PCIe 6.0 less than three years after the release of the PCIe 5.0 specification. The new standard helps reduce costs and enables data-intensive computing in data centers, AI/ML, HPC, automotive, IoT, military, aerospace, and more while maintaining compatibility with previous generations of technology.

Officials said that the solid-state drive SSD market is growing rapidly, with a compound annual growth rate of 40%. In the future, the requirements for speed will be further increased. The introduction of the PCIe 6.0 standard will meet the needs of the storage industry in the future, providing higher bandwidth and lower latency.

Moreover, PCIe 6.0 features four levels of PAM4 signal pulse amplitude debugging, which can take advantage of PAM4 technology already available in the industry. The standard features Lightweight Pre-Error Correction (FEC) and Cyclic Redundancy Check (CRC) functions to mitigate the increased bit error rate of PAM4 signaling with no impact on latency.

This standard updates the packet layout used in Fit Mode to provide additional functionality. The current solid-state drive using the PCIe 5.0 standard has just been launched, and no graphics card supporting PCIe 5.0 has been released yet.

Intel’s 12th-generation Core processor brings PCIe 5.0 support for the first time, and the AMD Ryzen 7000 series is also expected to support PCIe 5.0 in the next step. The application of the latest PCIe 6.0 standard is not expected to be seen until three years later.
