The PCI Special Interest Group has started finalizing the specifications of PCIe 7.0.

The PCI Special Interest Group (PCI-SIG) has begun finalizing some specifications of PCIe 7.0, the group revealed this Tuesday. They further shared that they expect the reveal at the start of 2025.

PCI Express is an underlying basic I/O standard that controls the PC’s two major components: the Discrete GPU and the System’s SSD. Both components continuously improve, demanding fast and high-performing bandwidth with the PCI Express standard.

Like older versions of PCI Express, the PCI 7.0 will boost the PCI Express 6.0 bandwidth, from 256GB/s to 512GB/s through dual direction and x16 interface.

PCIe doubles the bandwidth every three years

PCI-SIG further said that the PCIe 7.0 would have backward compatibility with older generations of the technology. Due to the way its specifications are designed, published, and deployed, the specification development process often anticipates the market presence of future products. For instance, the PCI Express 5.0 was introduced in May 2019; however, the first reveal of its finished product was launched as a part of Intel’s current 12th Gen Alder Lake processors in 2021.

The foundation of PCI Express 5.0 will be supported by AMD’s Ryzen 7000 processors. Moreover, the PCI Express 6.0 was planned to be launched in 2021, but its final specification was released later this January — expecting we would see the PCIe 6.0 product by 2023. If this trend continues, the PCI Express 7.0 will be introduced in 2025, but the final product may appear at the end of 2026 or the beginning of 2027.

Enterprise applications

In addition to this trend, the new standard is estimated to be focused on enterprise applications like quantum computing, artificial intelligence, machine learning, and high-end computing. The PCIe SIG has also planned on improving power efficiency, without revealing what such goals entail.

Laptop SSDs can quickly heat up under high performance and load, so it will be impressive to see what advancements the SIG will be making in this area. In any case, It will take several years before we see a finished product.
