Intel® Quickpath Interconnect Maximizes Multi-Core Performance
Maximizing multi-core processor performance
Intel® QuickPath Technology plays a key role in the latest generations of Intel® microarchitecture. Learn how it enables high performance in 2nd generation Intel® Core™ processors, Intel® Core™ processors, 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.
