PCIe® 3.0

PCI Express Version

PCI Express Revision is the supported version of the PCI Express standard. Peripheral Component Interconnect Express (or PCIe) is a high-speed serial computer expansion bus standard for attaching hardware devices to a computer. The different PCI Express versions support different data rates.

PCIe Version

PCI Express is a high-speed serial computer expansion bus standard used for connecting high-speed components, replacing older standards such as AGP, PCI, and PCI-X. It has gone through multiple revisions and improvements since its initial release. PCIe 1.0 was first introduced in 2002, and in order to meet the growing demand for higher bandwidth, subsequent versions have been released over time.

Memory Specifications

DDR4 - Up to 3200 MT/s, LPDDR4 - Up to 4266 MT/s

Memory Type

Intel® processors come in four different types: Single Channel, Dual Channel, Triple Channel, and Flex Mode. Maximum supported memory speed may be lower when populating multiple DIMMs per channel on products that support multiple memory channels.
