PCI-SIG announces latest PCI Express 7 target, expected to be eight times faster than PCIe 4.0

The PCI-SIG working group responsible for developing the PCE Express (PCIe) specification announced the preliminary goals of PCI Express 7 (PCIe 7.0) at the latest developer conference, which is expected to be faster than PCIe 5.0, which is currently being gradually introduced to the market. It is four times faster than the current mainstream PCIe 4.0. The original goal of PCI-SIG was to double the transmission speed every three years, but it is currently about three years ahead of schedule. It was originally scheduled to reach dual 512GB/s bandwidth in 2028, and it will be achieved in 2025. .

However, from the official release of the specification to the actual application by the manufacturer to the product, there will still be a certain delay. The PCIe 5.0 specification was launched in 2019, and it is just about to become popular this year; the PCIe 6.0 specification was launched in January this year, and the products on board will not be seen until two or three years later, and PCIe 7.0 is naturally the same , even if the specification can be finalized in 2025, I am afraid it will be a matter of 2027 or 2028 to see the product.

The continued doubling of PCIe speeds doesn’t mean that the speed of the device will increase with it. Graphics cards are probably the ones that make the most of this extra bandwidth, but things like storage don’t necessarily have the same speed. But on the other hand, if the storage speed remains the same and the channels are constantly accelerating, then the storage device that originally took up four channels (x4) in the PCIe 4.0 era will only need one in the PCIe 6.0 era. When it comes to PCIe 7.0, not only does it need to take up one, but there is still room for the SSD to accelerate again.
