Because of the interface speed, performance of the new storage media, and proximity to the CPU, PCI Express (PCIe) was the next logical storage interface. PCIe slots directly connect to the CPU providing memory-like access and can run a very efficient software stack. The subvendor and subdevice fields will be set to. PCIANYID./ #define PCIDEVICE(vend,dev).vendor =,.device = (dev),.subvendor = PCIANYID,.subdevice = PCIANYID /. PCIDEVICESUB - macro used to describe a specific PCI device with subsystem. @vend: the 16 bit PCI Vendor ID. @dev: the 16 bit PCI Device ID. @subvend: the 16. The PCI Express connector location and pinout options the same as PCI/104-Express (both Type 1 and Type 2). Because the PCI bus connector is omitted, a PCIe/104 board is incompatible with PC/104- Plus and PCI-104 systems (unless a PCIe-to-PCI bridge device is used). PCI Express slots deliver over 3.5 times more bandwidth than existing PCI slots, and they operate at near maximum throughput without slowing down other devices. MPC Computers introduces the NetFRAME 4620 server Your PC needs a free PCI slot (most PCs will have one) and the supplied drivers will run on any version of Windows from 98SE onwards.

Pci Interface
PCI Express
The common hardware interface in PCs, Macs and other computers for connecting peripheral devices such as storage drives and graphics cards. PCI Express (PCIe) was introduced in 2002 as 'Third Generation I/O' (3GIO), and by the mid-2000s, motherboards had at least one PCIe slot for graphics. PCIe superseded PCI and PCI-X.Switched Architecture - Multiple Lanes
Unlike its PCI predecessor, which used a shared bus, PCI Express is a switched architecture of up to 32 independent, serial lanes (x1-x32) that transfer in parallel. Each lane is full duplex (see illustration below).
Internal and External for Laptops
A mini PCIe came out for laptops (see Mini PCI Express) and Thunderbolt extends PCIe outside the computer (see external GPU). For PCIe/PCI comparisons, see PCI-SIG. See PC data buses, PCI, M.2, ExpressCard, Thunderbolt and PCI-X.
| Parallel Transfer of Serial Channels |
|---|
| Each lane is an independent single-bit serial channel. PCIe is a type of parallel transfer but each lane has its own clock, which differentiates it from earlier parallel technologies. |
| PCIe on the Motherboard |
|---|
| This Asus motherboard has four x1 and three x16 slots (two black, one beige). The x16 slots accommodate x16, x8 and x4 cards. (Image courtesy of ASUStek Computer Inc.) |
| M.2 Over PCIe |
|---|
| This is a 960GB NVMe SSD on an 80x20mm M.2 card. The connection is via PCIe, either via an M.2 socket on the motherboard or a PCIe adapter card. See M.2. |
| Different Sizes of PCI Express |
|---|
| PCIe sockets are not the same as PCI, and they come in x1, x4, x8 and x16 sizes. |
| PCIe Replaced AGP for Graphics |
|---|
| The AGP slot gave way to an x16 PCIe slot for the graphics card. (Image courtesy of NVIDIA Corporation.) |
