如果你主板上的M.2接口不够用，那你可以购买这种PCIex4的扩展卡来增加M.2接口的数量。 然而，大部分低端主板是没有第二条PCIe x16或x4的插槽，那这种情况该怎么办呢？ 其实，你不妨把眼光投向这些容易被忽视的PCIe x1的接口上。

根据 0.7 版规范描述，PCIe 7.0 的目标是在 PCIe 6.0 基础上实现带宽翻番，达到 128GT/s，这意味着在 16 通道（x16）配置下，双向传输速度可达 512GB/s。

You might have heard the term “bifurcation” if you’ve been around PCIe ... get sixteen x1 links out of a single x16 slot – usually, the supported combination is four x4 links out of ...

These are PCIe x1, x2, x4, x8, and x16; the more lanes you have available on a slot, the more data can be transmitted and received. The smallest PCIe slot (PCIe x1) has a single lane available and ...

and not all PCIe slots allow for every card to be installed. While any card of any configuration (x1, x4, x8 or x16) will fit and work in an x16 slot (mechanical), smaller slots may not physically ...

A four lane link has eight times the data rate in each direction of a conventional bus. Lattice’s PCI Express Root Complex (RC) Lite core provides an x1 or x4 root complex solution from the electrical ...

When attached to a motherboard's PCIe x16 slot ... through a single connector. PCIe x4 and x8 cards can draw up to 25W from the motherboard's slot, while x1 cards are limited to 10W unless ...

These popular PCIe MegaCore® functions (x1, x4, or x8 lane configurations) support all memory, I/O, configuration, and message transactions. The MegaCore functions have an optimized application ...

so that Gen 4.0 x4 link of yours can handle a total bandwidth of 16 GB/s (bi-directional) in PCIe Gen 4.0 mode, whereas the old Gen 1.0 x16 slot would be capable of 2GB/sec (bi-directional).
