Noun | /piː siː aɪ ˈiː/
A high-speed serial computer expansion bus standard used for connecting components like GPUs, SSDs, and network cards directly to the motherboard.
Key Features:
- Uses lanes (x1, x4, x8, x16 configurations)
- PCIe 4.0 offers up to 64 GB/s bandwidth
- Supports hot-plugging in some implementations
Example:
“Modern graphics cards require at least a PCIe x16 slot for optimal performance.”
