Although we have only just begun the PCI Express 5.0 (PCIe Gen 5) generation, the PCI Special Interest Group is currently looking ahead. Starting in 2025, you can expect the PCIe 7.0 specification to be established, the team said Tuesday.
PCI Express is the basic I/O requirement that, in the computer, governs two essential elements: the distinct GPU, along with the system’s SSD. Both elements are constantly improving, requiring ever faster transmission capacity than conventional PCI Express provides.
PCI Express 7.0 will follow the current pattern, increasing the transmission capacity of PCI Express 6.0 from 64 gigatransfers (256 GB/s) per second to 128 gigatransfers per second (512 GB/s), both bidirectionally and through a x16 user. Interface. PCIe 7.0 will also be backward compatible with modern technology, SIG said.
Due to the exact nature of how specs in silicon are developed, released, and then enforced, spec growth typically precedes actual market visibility of licensed items by years. PCI Express 5.0, for example, was introduced in May 2019, but was initially featured in full articles as a component of Intel’s existing 12th Gen “Alder Lake” CPU in late 2014. (Uses bi-directional speeds of 128GB /s .)
PCI Express 5.0 will no doubt be supported by AMD’s Ryzen 7000 CPU, too, this loss. PCI Express 6.0 was planned to be released in 2021, but the latest specification was released in January, suggesting we may see elements of PCIe 6.0 in 2023. If that pattern holds, PCI Express 7.0 will be released in 2025, with the team Initial PCIe 7.0 likely to appear in 2026 or 2027.

From a market standpoint, the new requirement is expected to focus on commercial applications, including a quantum computer, a high-performance computer, an expert system, and artificial intelligence. One exception is support for 800 gigabit Ethernet, an innovation that is nowhere near mainstream.
Otherwise, the features of PCIe 7.0 are what you would surely expect: it will certainly use PAM4 signaling. The PCIe SIG has also set “improve energy efficiency” as a goal, without stating what those goals might be. Laptop SSDs tend to accommodate themselves pretty well under tons, so it’ll definitely be interesting to see what strides SIG can make there. Regardless, it will be many years before consumers see the benefits.
