Intel® 64 Architecture

Intel® 64 Architecture

Intel® 64 architecture delivers 64-bit computing in embedded designs when combined with supporting software.1 Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.

Intel® 64 provides support for:

  • 64-bit flat virtual address space
  • 64-bit pointers
  • 64-bit wide general-purpose registers
  • 64-bit integer support
  • Up to one terabyte (TB) of platform address space

Products designed with Intel® 64 architecture

The Intel® Core™ vPro™ processor family arms business PCs with hardware-assisted security, manageability capabilities, and enhanced performance.

For desktops, the Intel® Core™ processor family offers the smartest and fastest processors from Intel. Adapting to the needs of users, the technology inside the 3rd generation Intel® Core™ processor family is designed to automatically adjust to shifting performance demands while reducing power consumption.

Laptops equipped with a processor from the Intel® Core™ processor family deliver unmatched mobile technology for intelligent performance—from digital video to intense games to demanding business tasks.

Intel® Xeon® processors power a variety of multi-core 64-bit servers and workstations. For a wide range of infrastructure, cloud, high-density, and high-performance computing (HPC) applications, the Intel® Xeon® processor E5 family offers versatile one-way and two-way 64-bit multi-core servers and workstations. Intel® Xeon® processor E7 family provides exceptional scalable performance and mission-critical class reliability for the most data-demanding applications and virtualization projects.

Product and Performance Information


1. 64-bit computing on Intel® architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers, and applications enabled for Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software configurations. Consult with your system vendor for more information.
