Maximizing Multicore Processor Performance

Intel® QuickPath Technology plays a key role in the latest generations of Intel® microarchitecture. Learn how it enables high performance in Intel® Core™ and Intel® Xeon® processors.

Point-to-Point Links Speed Up Data Movement

Intel® QuickPath Technology uses Intel® QuickPath Interconnect, which provides high-speed, point-to-point links inside and outside of the processor. In contrast to parallel buses, these links speed up data transfers by connecting distributed shared memory, the internal cores, the I/O hub, and other Intel® processors.

Integrated memory controllers and Intel QuickPath Technology work together to deliver:

  • Scalable, high-performance communications
  • Outstanding memory performance and flexibility to support leading memory technologies
  • Tightly integrated interconnect reliability, availability, and serviceability (RAS)
  • Configurations allowing optimal balance of price, performance, and energy efficiency

Faster Flow, More Dependable Microarchitecture

The previous generation of processors used slower, parallel front-side-bus architectures. Intel® QuickPath Technology accelerates the flow of data by introducing multiple pairs of high-speed serial links. By grouping several paths together with intelligent management, Intel QuickPath Technology can deliver up to 25.6 GB/s between components and maintain communications even when a link fails.
