Intel has also played a key role in the development of various PC hardware standards, including the following:

  • USB 1.1, 2.0, and 3.0 are serial bus standards for connecting peripheral devices.
  • Thunderbolt is a high-speed serial data interface that combines PCI-Express and DisplayPort into one cable.
  •  Local bus interface for the Peripheral Component Interconnect (PCI).
  • The Accelerated Graphics Port (AGP) is a PCI-based interface for higher-performance video cards.
  • The PCI Special Interest Group (PCI SIG) chose PCI Express (formerly known as 3GIO) to replace both PCI and AGP as the high-performance bus for PCs.
  • ATX (including variations such as microATX and FlexATX) and BTX (containing variations such as microBTX, nanoBTX, and picoBTX) are industry-standard motherboard form factors. The ATX form factor is still the most common, and it superseded the rather outdated IBM-designed Baby-AT form factor, which had been in use since the early 1980s, beginning in 1996–1997.
  • The connections, wires, and signals used to link motherboards to external switches, LEDs, and front ports on industry-standard chassis are known as the Front Panel I/O form factor.
  • To offer a standard approach for operating Serial ATA (SATA) host adapters, the Advanced Host Controller Interface (AHCI) was created.
  • HD Audio is a PCI bus specification that defines the design and control of audio controllers.
  • Wireless Display (WiDi) uses a wireless connection to send 1080p HD video and 5.1 surround sound from devices to monitors.
  • For monitoring system hardware functions, use the Desktop Management Interface (DMI).
  • PC power management standards include Dynamic Power Management Architecture (DPMA), Advanced Power Management (APM), and Advanced Configuration and Power Interface (ACPI).
Intel controls not only the PC market but also the whole global semiconductor industry. Intel has more than 40 percent greater sales income than the next closest semiconductor business (Samsung) and over ten times that of competitor AMD, according to iSuppli sales estimates.
