Many people have not yet used PCIe 5.0 SSD, but in many professional fields, the desire for high bandwidth is endless, including but not limited toArtificial intelligence, high-performance computing, large-scale data centers, high-speed networks, edge computing, quantum computing, automotive, and more.Nowadays, PCIe 6.0 and PCIe 7.0 have been born one after another, and PCIe 8.0 is also in preparation!
The PCIe 8.0 standard was announced in early August last year, and the draft version v0.3 was quickly completed. The final official version is expected to be released in 2028.
However, although standards and specifications are still being formulated, ecological manufacturers have already taken action.
At the DesignCon 2026 conference, Synopsys demonstrated PCIe 8.0 level electrical performance for the first time, including eye diagram testing, receiving end, etc.
As designed, Synopsys demonstrated that PCIe 8.0 can already reach a per-channel bandwidth of 256GT/s, and the bidirectional bandwidth under x16 full link can be as high as 1TB/s.
However, as usual, Synopsys just used existing chips and technologies to demonstrate the physical layer PHY IP of PCIe 8.0. In other wordsJust an early milestone in signal integrity, physical aspects, and far from a true PCIe 8.0 controller.
Of course, ordinary consumers can just take a look. After all, it is still early for consumer-grade PCIe 6.0 SSDs, graphics cards, and motherboards to be launched.
