Thus, Intel describes a 20-lane QPI link pair (send and receive) with a 3.2 GHz clock as having a data rate of 25.6 GB/s. A clock rate of 2.4 GHz yields a data rate of 19.2 GB/s. More generally, by this definition a two-link 20-lane QPI transfers eight bytes per clock cycle, four in each direction. The rate is computed as follows: 3.2 GHz
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.
The Intel Ultra Path Interconnect (UPI) [1] [2] is a scalable processor interconnect developed by Intel which replaced the Intel QuickPath Interconnect (QPI) in Xeon Skylake-SP platforms starting in 2017.
The front-side bus was criticized by AMD as being an old and slow technology that limits system performance. [10] More modern designs use point-to-point and serial connections like AMD's HyperTransport and Intel's DMI 2.0 or QuickPath Interconnect (QPI).
Coherent Accelerator Processor Interface (CAPI), is a high-speed processor expansion bus standard for use in large data center computers, initially designed to be layered on top of PCI Express, for directly connecting central processing units (CPUs) to external accelerators like graphics processing units (GPUs), ASICs, FPGAs or fast storage.
Since there is no official marketing information about it yet, it's still difficult to say. However, going by the number of hits on Google right now: "Common Serial Interconnect" has about 95 hits, "Common System Interconnect" has about 109 hits, "Common System Interface" has about 9380 hits. -- Bovineone 15:40, 13 December 2006 (UTC)
LGA 1356, also called Socket B2, is an Intel microprocessor socket released in Q1 2012 with 1356 Land Grid Array pins. It launched alongside LGA 2011 to replace its predecessor, LGA 1366 (Socket B) and LGA 1567. [1]
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]
