The Intel QuickPath Interconnect is a highspeed, packetized, point-to-point interconnect used in Intel’s next generation of microprocessors first produced in the second half of 2008. The narrow high-speed links stitch together processors in a distributed shared memory-style platform architecture. Compared with today’s wide front-side buses ...
Intel QuickPath Interconnect או בשמה הקצר "QuickPath" (קודם לכן בשם "Common System Interface" או בשמה הקצר "CSI") היא טכנולוגיית תקשורת נקודה-לנקודה במעבדים המתוכננים ומפותחים על ידי חברת אינטל אשר אמורים להתחרות בטכנולוגיית ה-HyperTransport המפותחת תחת ...
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. Comparing to QPI, it improves power efficiency with a new low-power state ...
快速通道互联 （英語： Intel QuickPath Interconnect ，縮寫：QPI） ，是一種由英特爾開發並使用的點對點處理器互聯架構，用來實現CPU之間的互聯。 英特爾在2008年開始用QPI取代以往用於 至強 、 安騰 處理器的 前端匯流排 （ FSB ）。
The Intel QuickPath Interconnect (QPI) is a point-to-point 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
Intel QuickPath Architecture is a key platform ingredient in new upcoming Intel Xeon and Intel® Itanium® processor –based server and workstation platforms. This will mark the first time that these two server platforms share the same architecture and interconnect. This will simplify system design for the original equipment manufacturers (OEMs).
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.
