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.
