The Intel QuickPath Interconnect (QPI) [1] [2] is a scalable processor interconnect developed by Intel which replaced the front-side bus (FSB) in Xeon, Itanium, and certain desktop platforms starting in 2008. It increased the scalability and available bandwidth. Prior to the name's announcement, Intel referred to it as Common System Interface ...
The Intel X58 (codenamed Tylersburg) is an Intel chip designed to connect Intel processors with Intel QuickPath Interconnect (QPI) interface to peripheral devices. Supported processors implement the Nehalem microarchitecture and therefore have an integrated memory controller (IMC), so the X58 does not have a memory interface.
More modern designs use point-to-point and serial connections like AMD's HyperTransport and Intel's DMI 2.0 or QuickPath Interconnect (QPI). These implementations remove the traditional northbridge in favor of a direct link from the CPU to the system memory, high-speed peripherals, and the Platform Controller Hub, southbridge or I/O controller.
UPI is a low-latency coherent interconnect for scalable multiprocessor systems with a shared address space. It uses a directory-based home snoop coherency protocol with a transfer speed of up to 10.4 GT/s. Supporting processors typically have two or three UPI links.
The Scalable Coherent Interface or Scalable Coherent Interconnect (SCI), is a high-speed interconnect standard for shared memory multiprocessing and message passing.The goal was to scale well, provide system-wide memory coherence and a simple interface; i.e. a standard to replace existing buses in multiprocessor systems with one with no inherent scalability and performance limitations.
It contains a significant amount of data which contradicts the Intel docs on QPI; the rest of the data seem to be flat-out fabricated. For example, QPI is not a 4 layer interconnect. --unsigned according to the Intel paper listed as a reference, QPI is a 5-layer interconnect, which is what the article says.
The Arm Advanced Microcontroller Bus Architecture (AMBA) is an open-standard, on-chip interconnect specification for the connection and management of functional blocks in system-on-a-chip (SoC) designs. It facilitates development of multi-processor designs with large numbers of controllers and components with a bus architecture. Since its ...
Both Intel CPU families share a common chipset; the interconnection is called Intel QuickPath Interconnect (QPI), which provides extremely high bandwidth to enable high on-board scalability and was replaced by a new version called Intel UltraPath Interconnect with the release of Skylake (2017). [7]
