PCI-SIG Announces PCIe 6.0 Specification
PCI-SIG today announced that PCI Express 6.0 technology will double the data rate to 64 GT/s while maintaining backward compatibility with previous generations and delivering power efficiency and cost-effective performance.
The PCI SIG announced PCI Express 6.0 on Tuesday, scheduled to bring I/O transfer rates of 256 gigabytes per second (GBps) in a few years. Targeted for release in 2021, the PCIe 6.0 technology will double the data rate to 64 GT/s and up to 256 GB/s via x16 configuration while maintaining backward compatibility with previous generations.
PCIe 6.0 Specification Features
- Delivers 64 GT/s raw bit rate and up to 256 GB/s via x16 configuration
- Utilizes PAM-4 (Pulse Amplitude Modulation with 4 levels) encoding and leverages existing 56G PAM-4 in the industry
- Includes low-latency Forward Error Correction (FEC) with additional mechanisms to improve bandwidth efficiency
- Maintains backwards compatibility with all previous generations of PCIe technology
"PCI Express technology has established itself as a pervasive I/O technology by sustaining bandwidth improvements for five generations over two decades," Dennis Martin, an analyst at Principled Technologies, said. "With the PCIe 6.0 specification, PCI-SIG aims to answer the demands of such hot markets as Artificial Intelligence, Machine Learning, networking, communication systems, storage, High-Performance Computing, and more."
"Continuing the trend we set with the PCIe 5.0 specification, the PCIe 6.0 specification is on a fast timeline," Al Yanes, PCI-SIG Chairman and President, said. "Due to the continued commitment of our member companies, we are on pace to double the bandwidth yet again in a time frame that will meet industry demand for throughput."PCI-SIG is the consortium that owns and manages PCI specifications as open industry standards. The organization defines industry standard I/O (input/output) specifications consistent with the needs of its members. Currently, PCI-SIG is comprised of over 800 industry-leading member companies.

Are you suffering from USB3.2 marketing withdrawal? Have you been hostage to PCIe 3.0 bandwidth long enough to develop the Stockholm Syndrome?
Relax, PCIe is just a high-performance serial interface which always performs as advertised by its version number, unlike those god-forsaken "USB 3.2 Gen 1x1" whatever.

Zen4 EPYC Genoa is planned for a 2021 release - and includes PCIe 5.0

Also new Socket SP5 and DDR5 memory (but still no 'chipset' to put a heatsink on).

my uncle works at PCI-SIG and told me about PCIe 7.0 he even let me build it into my rig its got mode7 AND blast processing which is the trick to resurrecting Aerith in FF7
