PCI-SIG has confirmed that version 0.7 of the PCIe 6.0 standard has been released to the organisation's members, bringing the high bandwidth interconnect one step closer to widespread adoption. While PCIe 4.0 remains the new hotness in the PC market, hardware enthusiasts should know that PCI-SIG, the organisation behind the standard, plans to bring the performance of its interconnection standard to new heights. The PCIe 5.0 standard has already been ratified, and full PCIe 6.0 specification is due to be released in 2021. 

PCIe 6.0 will be the new hotness when it comes to PC interconnectivity, packing a 2x increase in transfer speeds over PCIe 5.0, a 4x boost in raw bit rate over PCIe 4.0 and a whopping 8x improvement over what PCIe 3.0 configuration can deliver. For context, that allows a single PCIe 6.0 lane to offer users as much bandwidth as a PCIe 3.0 8x lane configuration, which is more than enough bandwidth for most of today's graphics cards.  Right now, PCIe 6.0 has met most of the design requirements of the standard and has exceeded expectations in some regards. Even so, improvements still need to be made with regards to power consumption, though the addition of a new L0p power state should address these complaints.  
 
With PCIe 6.0, PCI-SIG will add a new form of error correction called Forward Error Correction (FEC), which will help to improve the reliability of PCIe 6.0 and help to increase the standard's bandwidth efficiency. Combine this with PAM4 signalling, and PCIe 6.0 is due to deliver the bandwidth requirements of the standard with ease. 

PCIe 6.0 is designed to meet the needs of future devices within the PC and enterprise markets, with Machine Learning, Artificial Intelligence, cloud computing and data storage being primary concerns for the industry. With 800G Ethernet cards coming this year, and even faster standards being on the horizon, faster PCIe interconnects will become vital for the industry moving forward. With PCIe 6.0, PCI-SIG plans to meet the performance needs of the industry while doing so at a low cost. The backwards compatibility of the standard will also be useful for many markets, as it allows some older hardware to be maintained withing newer networks. 


To put the performance of PCIe 6.0 into context, it could enable M.2 devices to deliver speeds that are up to eight times faster than today's Samsung 970 Pro series SSD, which is widely regarded as one of the best performing PCIe 3.0 M.2 SSDs on the market. Another way to put it is with PCIe 6.0, the performance of a PCIe 3.0 16x configuration is equivalent to two PCIe 6.0 lanes. 

PCIe 6.0 will enable higher levels of bandwidth for those who need it while granting PC users access to today's bandwidth levels over fewer PCIe lanes. The only problem with this rapid evolution is that new PCIe 4.0 devices will soon find themselves replaced with PCIe 5.0 and then PCIe 6.0 over the next 5 or so years. That said, should we complain about technology progressing too quickly? 
 
In my personal opinion I wonder if the technology is moving too fast?

6.0 ?  - we haven't even gotten full saturation on 4.0 yet .

Geez, Just pick one and go with it!

Cool GTX
which was first chicken or the egg .... they need the Standard to be in place .. manufactures will then decide on production viabilities

"a single PCIe 6.0 lane to offer users as much bandwidth as a PCIe 3.0 8x lane configuration, which is more than enough bandwidth for most of today's graphics cards. "

Well that sounds very nice, unfortunately we're only just recently starting to see PCIe 4.0 hardware availability becoming mainstream lol. By the time hardware reaches PCIe 6.0 as mainstream, the boffins will be releasing PCIe 12.0.

Intel will be adopting PCIe 5 in the server space in 2021 and AMD probably will be doing the same give or take a year. Intel needs 5.0 to enable Compute Express Link. This means we may see faster than usual adoption of 5.0 on consumer hardware...

I thought I read that they already committed to Q4 2021?

Yes, I meant 2021 sorry! Fixed my post. It already feels like 2021

wait.. so .... huh?? 
 
what happened to version 4.0 and  5.0??
