For desktop system users, here are a few real winning scenarios.
PCI-SIG, the industrial consortium responsible for defining PCI-Express bus specifications, PCI-Express 7.0, Or just PCIe 7.0, which will be officially released in 2025. As with every new version, PCIe 7.0 has doubled its data transfer capability compared to PCIe 6.0, with a maximum transfer rate of 128 GT / s and 512 GB / s. Bilateral, large numbers through the x16 slot, which should bring real benefits, especially for SSDs and data networks.
Here are the highlights of PCI-Express 7.0:
– Maximum bit rate 128 GT / s and 512 GB / s two way via PCI-Express x16
– PAM4 system (4 levels of pulse amplified modulation)
– Pay attention to channel parameters and promised access.
– Low delay and high reliability
– Improved energy efficiency
– Compatible with all previous PCIe generations
PCIe 7.0 is 4 times faster than the PCIe 5.0 that has just hit the market.
The tables below show progress in the specifications of all versions of the PCI-Express bus, which is 64 times faster than PCIe 1.0 in PCIe 7.0. Note that PCIe 7.0 will be able to access the PCI-Express x4 card. PCIe 5.0 x16 speed.
With the PCI-Express 7.0 specification, PCI-SIG believes it will provide advances in emerging applications such as 800G data networking, quantum computing, data intensive data centers, high performance computing, military and aerospace solutions. ۔

PCI-Express Bus is currently the best solution for high demand data traffic due to the advances made with each new version. As a level of comparison, PCI-Express 5.0 (PCIe 5.0) has recently effectively reached the consumer market, with a few solutions that manage to reap real benefits, as highlighted above. SSDs (Solid State Storage Drives) are among the products that benefit from this development, but in very specific use conditions. Who can benefit from such fast SSDs? Especially data centers with servers that demand more data traffic. For mainstream users, PCIe 4.0 SSDs already provide high speeds, with the latest models exceeding 7000 MB / s.
It is worth noting that video cards are also updated with support for the new PCI-Express buses, but this does not bring real benefits in performance when considering models based on the traditional x16 slots, and PCIe Versions like 3.0 x16 also do not limit. Chips Performance However, newer buses outperform others by the speed of x8, x4 resolution, providing these buses with better performance cards, which is exactly where the limit is. Another explanation is that high-speed buses “support more energy”, so solutions for power supply by bus are possible, without the need for power cables.
PCIe 5.0 solutions have just hit the market, and PCIe 7.0 will be many years away.
Introducing PCI-Express to the computer world, the first models with PCIe 5.0 support recently came on the market through the Intel with the 12th generation core. AMD will use the same bus in newer models of the Ryson 7000 line, which will hit the market later this year.
Solutions with PCIe 6.0 have no official predictions of reaching the consumer market yet, let alone PCIe 7.0, which can take years.
