PCIe 1.x is often quoted to support a data rate of 250MB/s in each direction, per lane. This figure is a calculation from the physical signaling rate (2.5 gigabaud) divided by the encoding overhead (10 bits per byte). This means a sixteen lane (x16) PCIe card would then be theoretically capable of 16x250MB/s = 4GB/s in each direction. While this is correct in terms of data bytes, more meaningful calculations are based on the usable data payload rate, which depends on the profile of the traffic, which is a function of the high-level (software) application and intermediate protocol levels. On 11 March 2019, Intel presented Compute Express Link (CXL), a new interconnect bus, based on the PCI Express 5.0 physical layer infrastructure. The initial promoters of the CXL specification included: Alibaba, Cisco, Dell EMC, Facebook, Google, HPE, Huawei, Intel and Microsoft. [143] Integrators list [ edit ]PCI Express3.0 upgraded the encoding scheme to 128b/130b from the previous 8b/10b encoding, reducing the bandwidth overhead from 20% of PCI Express2.0 to approximately 1.54% (=2/130). PCI Express 3.0's 8GT/s bit rate effectively delivers 985MB/s per lane, nearly doubling the lane bandwidth relative to PCI Express 2.0. [48]

Draft 0.9 (Final draft): this release allows PCI-SIG member companies to perform an internal review for intellectual property, and no functional changes are permitted after this draft.

PCI Express Mini Card (also known as Mini PCI Express, Mini PCIe, Mini PCI-E, mPCIe, and PEM), based on PCI Express, is a replacement for the Mini PCI form factor. It is developed by the PCI-SIG. The host device supports both PCI Express and USB2.0 connectivity, and each card may use either standard. Most laptop computers built after 2005 use PCI Express for expansion cards; however, as of 2015 [update], many vendors are moving toward using the newer M.2 form factor for this purpose.
