The PCI-SIG Committee has disclosure the latest PCI Express 7.0 standard with lightning speed, even as we wait for the older two-generation version 5 . PCIe Device to come to the quantity. Slated to launch in 2025 and likely to hit shelves around 2027, PCIe 7 will deliver speeds of up to 512 GB/s, 8 times the speed of the latest PCI Express 5.0.
512GB/s bidirectional speeds will be available on x16 connections, but will be significantly reduced in the real world due to cost-effective encryption and header efficiency. However, it’s double the PCI 6.0 standard that is supposed to launch later this year. PCI-SIG (which now hosts its annual developer conference) says it is ahead of its goal of doubling PCI Express speeds every three years.
However, all these speeds depend on the device and chip manufacturer. Intel’s 12th-generation Alder Lake chips released in January 2022 support PCIe 5.0, but AMD’s Ryzen 7000 Zen 4 desktop chips with PCIe 5.0 support won’t arrive until this fall. The first consumer PCIe 5.0 SSDs with just arrived with read speeds up to 13GB/s.
Other key features include improved power efficiency, low latency, and backward compatibility with previous generations. However, PCIe 7.0 will require a shorter time to reach that speed, so motherboards can be more expensive. may request extra components and thicker PCB.
On the plus side, even x1 lanes of PCIe 7.0 will be as fast as PCIe 4.0 x16 (32 GB/s), so memory and other devices can be smaller and consume less resources. In other words, you can have four NVME SSD slots with each slot using only 1 PCIe lane, and all of them will be twice as fast as a PCIe5 x4 NVMe slot.
