With the previous standard, a PCIe x1 port has a total bandwidth of 2GB/s, PCIe x4 has 8GB/s, PCIe x8 uses 16GB/s, and PCIe ...

For a full 16-lane PCIe 6.0 connection, that's as much as 256GB/s of total bandwidth, compared to the 32GB/s or 64GB/s of now-common PCIe 3.0 and 4.0 connections.

A single PCIe 4.0 lane provides bandwidth of about 4GB per second, and you need eight of those lanes to offer the same speeds as a single PCIe 7.0 lane. Putting PCIe 7.0's speed increases in context.

It’s not too hard to believe that PCIe 6 will need even more aggressive cooling, and PCI Express bandwidth throttling and link-width control may be an unfortunate side effect in extreme scenarios.

Two PCIe 7.0 lanes can match the bandwidth of sixteen PCIe 4.0 lanes, which could see NVMe SSD speeds skyrocket and benefit future graphics cards too Samuel Willetts Published: Jun 22, 2022 ...

In short, with PCIe 5.0 there's obviously not going to be an issue, and indeed with PCIe 4.0, even though it's a slower standard that's being cut in half (only 8 lanes, rather than the full 16 ...
