With 64 Gbps bandwidth per lane, 256 Gbps in x4, and a whopping 1 Tbps in x16 (128 GB/s per direction), PCI-Express 6.0 will debut in 2021 as 5G adoption hits critical mass in markets across the globe, to support server nodes, high-bandwidth network infrastructure, and lighting fast I/O for HPC and AI applications. Development of the new standard is already underway, with the specification having achieved a pre-release version 0.3, according to the PCI-SIG, the body that develops and maintains the PCI IP.

Further development, prototyping, and testing of the standard will run through 2020 as drafts of the standard are dispatched to interested parties. With the specification published in 2021, the first devices implementing it could arrive the following year. Granted, very few devices need 1 Tbps bandwidth, but the exercise of doubling bandwidth every 3 or so years has its maximum impact on devices that only have wiring for one PCIe lane, and directly impacts bandwidth of other I/O specifications that are derived from PCIe, such as USB, Thunderbolt, CXL, etc.
 
I personally believe such an adoption will benefit Enterprise environments which serve 5G networks first. 

Specifications - Need to be established well before hardware design starts
 
who saturates PCIe 3.0 bandwidth already ?
 
PCIe 4.0 & 5.0 will rule - till 2022 - 2023

The switch to PAM was originally scheduled to be on PCIe 5.0, or at least it was stated in the tech news articles and posted on the PCI Express wiki.  Looks like I will be waiting for PCIe 6.0 when I was originally going to wait for 5.0 when it would make the switch to PAM and I knew 6.0 was to be released in this time frame.

The spec for 6.0 will be finalized in 2021 it will be another 18 months before we see consumer devices. Enterprise is always first.

Re. JPSHRACER1486;
I don't know about video cards yet, but Gigabyte has a PCIe 4.0 AIC SSD that runs at 4x .
8TB, my, my .
They've got an X299"X" board to run it, too .
 

• Form Factor: PCl Express Card
• Interface: PCI-Express 4.0 x16, NVMe 1.3
• Total Capacity: 8,000GB*
• Seq. Read Speed: up to 15,000 MB/s**
• Seq. Write Speed: up to 15,000 MB/s**
• Wear Leveling, Over-Provision Technologies
• TRIM & S.M.A.R.T Supported
• Advanced Thermal Solution with Copper Heatsink
• Warranty: Limited 5-years

I think they meant to say 8,000 MB, not GB .

8TB PCIe 4.0 NVMe SSD?  Nope, it's legit. 

cotter32
It's on their web site .  Don't know if you can actually buy one yet .
 
Too the moon !

8,000 GB = 8 TB

Re. GTXJackBauer
Thanks, got it . 
It strikes me that if Gigabyte is going the right way with this, it could eventually make M2, and SATA
connectors obsolete .  This, and integrated graphics could make a small, compact
desk top computer with lots of fast storage .  Kind of a high performance

Bandwidth is only part of it. You would also need fast rapid data transfers of small amounts of information while this might be better at large transfers of information at a slower rate. NVIDIA link would allow them total control over what they want.
