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.

The PCIe 6.0 specification is actively targeted for release in 2021.

I lost count, honestly. PCIe version... some number? USB whatever point... something?

PCIE 4.0 is already more expensive to implement. You really need a chipset made on a 10nm/7nm process to be efficient enough to not need active cooling. Then you have increased signaling so you need short clean traces which can increase motherboard layers all making it more costly.
PCIE 5.0 is going into servers. Intel and AMD are not bringing PCIE 5.0 into desktops in the near future(5 years or less) as its complete overkill and is very costly right now. PCIE 6.0 is also going to live in server for many years as well.
I suspect once we get to the point of making chipsets using a 3nm GAAFET process we would see PCIE 5.0 in the desktop space as that should get us a nice passively cooled cheap chipset.
Unlike in the past we can make faster interconnects with current technology so we will have some used in servers where it makes the most since and some used in desktops where it makes the most since.

Maybe it's like web browsers. They just start releasing 4, 5, 6 just months apart and in a few years we have PCIe 42.0. I mean, I'm on Chrome 75. Its pretty much the same as Chrome 28-74?

That will be while before that even happens 7nm still isnt a thing less i missing something

I can't help but feel that these announcements should of came after AMD released their x570 chipset, the misinformed may hold off buying anything pcie 4 knowing 5 and 6 are on the way, I know people on here know it won't make too much difference
