For desktop system consumers, there are few real win scenarios
PCI-SIG, the industrial consortium responsible for defining the specifications of the PCI-Express bus, made official the PCI-Express 7.0or just PCIe 7.0, which will be officially released in 2025. As has happened with each new version, PCIe 7.0 has doubled the data transmission capacity compared to PCIe 6.0, reaching a transfer rate of 128 GT/s and 512 GB/s maximum bidirectional via x16 slot, very high numbers that should bring real benefits especially for SSDs and data networks.
As major highlights of PCI-Express 7.0 we have:
– Maximum bitrate of 128 GT/s and 512 GB/s bi-directional via PCI-Express x16
– PAM4 system (Pulse Amplitude Modulation of 4 levels)
– Focus on channel parameters and promised reach
– Low latency and high reliability
– Better energy efficiency
– Compatibility with all previous PCIe generations
PCIe 7.0 is 4 times faster than PCIe 5.0 that just hit the market
The tables below show the progress in specifications of all versions of the PCI-Express bus, which in PCIe 7.0 is 64 times faster than PCIe 1.0. Note that in PCIe 7.0 it will be possible for a PCI-Express x4 card to reach the same speed a PCIe 5.0 x16.
With the PCI-Express 7.0 specification, PCI-SIG believes it will provide advances in solutions for emerging applications such as 800G data networking, quantum computing, data-intensive data centers, high-performance computing, military and aerospace, between others.

The PCI-Express bus is currently the best solution for high demand data traffic due to the advancement it receives with each new version. As a level of comparison, PCI-Express 5.0 (PCIe 5.0) effectively reached the consumer market recently, with few solutions that manage to reap real benefits, as highlighted above. SSDs (Solid State Storage Drive) are among the products that benefit from this advancement, but in very specific usage scenarios. Who can take advantage of such fast SSDs? Especially data centers with servers that demand high data traffic. For traditional consumers, PCIe 4.0 SSDs already deliver blazing speeds, with the latest models exceeding 7000 MB/s.
It is also worth mentioning that video cards are also updated with support for the new PCI-Express buses, but that traditionally do not bring real performance gains when considering models based on x16 slots, and even versions such as PCIe 3.0 x16 do not limit the performance of chips. However, the new buses advance in the speed of x8, x4 solutions among the others, providing cards based on these buses with better performance, which is precisely where the limitation is. Another detail is that faster buses “support more energy”, so solutions with power supply via the bus are possible, without the need for power cables.
PCIe 5.0 solutions have just hit the market, and PCIe 7.0 will be several years away
Bringing PCI-Express to the computer world, the first models with PCIe 5.0 support recently hit the market through Intel with the 12th generation Core. AMD will implement this same bus in the new models of the Ryzen 7000 line, which hit the market at the end of the year.
Solutions with PCIe 6.0 still don’t have an official forecast to reach the consumer market, let alone PCIe 7.0, which could take years.
