145-411: A computer system, a chipset is a set of electronic components on one or more integrated circuits that manages the data flow between the processor , memory and peripherals . The chipset is usually found on the motherboard of computers. Chipsets are usually designed to work with a specific family of microprocessors . Because it controls communications between the processor and external devices,
174-496: A single Promontory 21 chipset for all configurations that include a chipset. A single Promontory 21 chip provides four SATA III ports and twelve PCIe 4.0 lanes. Four lanes are reserved for the chipset uplink to the CPU while another four are used to connect to another Promontory 21 chip in a daisy-chained topology for X670, X670E and X870E chipsets. The sTR5 socket has two chipset options available, TRX50 and WRX90: Chipset In
203-449: A traditional northbridge to do so. Intel followed suit in 2008 with the release of its Core i series CPUs and the X58 platform. In newer processors integration has further increased, primarily through the inclusion of the system's primary PCIe controller and integrated graphics directly on the CPU itself. As fewer functions are left un-handled by the processor, chipset vendors have condensed
232-555: The Intel 80286 CPU. In home computers , game consoles, and arcade hardware of the 1980s and 1990s, the term chipset was used for the custom audio and graphics chips. Examples include the Original Amiga chipset and Sega 's System 16 chipset. In x86 -based personal computers, the term chipset often refers to a specific pair of chips on the motherboard: the northbridge and the southbridge . The northbridge links

One nanometre can be expressed in scientific notation as 1 × 10 m and as 1 / 1 000 000 000 m. The nanometre
290-727: The NCR 53C9x , a low-cost chipset implementing a SCSI interface to storage devices, could be found in Unix machines such as the MIPS Magnum , embedded devices, and personal computers. Traditionally in x86 computers, the processor's primary connection to the rest of the machine was through the motherboard chipset's northbridge. The northbridge was directly responsible for communications with high-speed devices (system memory and primary expansion buses, such as PCIe, AGP, and PCI cards, being common examples) and conversely any system communication back to
319-617: The 1990s, a major designer and manufacturer of chipsets was VLSI Technology in Tempe, Arizona. Some of their innovations included the integration of PCI bridge logic, the GraphiCore 2D graphics accelerator and direct support for synchronous DRAM, the forerunner of DDR SDRAM memory. The Apple Macintosh SE , Macintosh II and later the Quadras series used chipsets from VLSI Technology , even though they were ASICs designed by Apple. After

In many modern chipsets, the southbridge contains some on-chip integrated peripherals , such as Ethernet , USB , and audio devices. Motherboards and their chipsets often come from different manufacturers. As of 2021 , manufacturers of chipsets for x86 motherboards include AMD , Intel , VIA Technologies and Zhaoxin . In
406-602: The X399, TRX40 and WRX80 motherboards' CPU sockets use the same number of pins, the sockets are incompatible with each other due to ID pins and no-connects of some pins. Three WRX80 motherboards were released at launch in March 2021. The WRX80 chipset does not support the HD Audio interface on its own, so motherboard vendors must include a USB audio device or a PCIe audio device on WRX80 motherboards to integrate audio codecs. AMD uses
435-595: The X399, TRX40 and WRX80 motherboards' CPU sockets use the same number of pins, the sockets are incompatible with each other due to ID pins and no-connects of some pins. Twelve TRX40 motherboards were released at launch in November 2019. The TRX40 chipset does not support the HD Audio interface on its own, so motherboard vendors must include a USB audio device or a PCIe audio device on TRX40 motherboards to integrate audio codecs. Supports 3rd (3900WX) and 4th generation (5900WX) AMD Ryzen Threadripper Pro processors. Although
464-505: The Zen architecture, there's still a component called a chipset which only handles relatively low speed I/O such as USB and SATA ports and connects to the CPU with a PCIe connection. In these systems all PCIe connections are routed directly to the CPU. The UMI interface previously used by AMD for communicating with the FCH is replaced with a PCIe connection. Technically the processor can operate without
493-566: The absence of an alternative AMD chipset." It is concluded that motherboards with the Knoll Activator would be built with I/O from the processor and low-cost I/O chips. Individual chipset models differ in the number of PCI Express lanes, USB ports, and SATA connectors, as well as supported technologies; the table below shows these differences. The 300 series, 400 series, and the B550 chipsets are designed in collaboration with ASMedia and
522-552: The chipset plays a crucial role in determining system performance . Sometimes the term "chipset" is used to describe a system on chip (SoC) used in a mobile phone. In computing , the term chipset commonly refers to a set of specialized chips on a computer 's motherboard or an expansion card . In personal computers , the first chipset for the IBM PC AT of 1984 was the NEAT chipset developed by Chips and Technologies for

Supports 3rd generation AMD Ryzen Threadripper (3960X to 3990X) processors. Although
609-454: The interface between a northbridge and southbridge was the PCI bus. Before 2003, any interaction between a CPU and main memory or an expansion device such as a graphics card(s) — whether AGP , PCI or integrated into the motherboard — was directly controlled by the northbridge IC on behalf of the processor. This made processor performance highly dependent on the system chipset, especially

#1732797786684638-454: The northbridge's memory performance and ability to shuttle this information back to the processor. In 2003, however, AMD's introduction of the Athlon 64 series of processors changed this. The Athlon 64 marked the introduction of an integrated memory controller being incorporated into the processor itself thus allowing the processor to directly access and handle memory, negating the need for
667-427: The parent unit name metre (from Greek μέτρον , [metrοn] Error: {{Lang}}: Non-latn text/Latn script subtag mismatch ( help ) , "unit of measurement"). Nanotechnologies are based on physical processes which occur on a scale of nanometres (see nanoscopic scale ). The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.06 nm, and that of
696-532: The processor. This connection between the processor and northbridge is commonly designated the front-side bus (FSB). Requests to resources not directly controlled by the northbridge were offloaded to the southbridge, with the northbridge being an intermediary between the processor and the southbridge. The southbridge handled "everything else", generally lower-speed peripherals and board functions (the largest being hard disk and storage connectivity) such as USB, parallel and serial communications. In 1990s and early 2000s,
725-423: The release of the Zen architecture, there's still a component called a chipset which only handles relatively low speed I/O such as USB and SATA ports and connects to the CPU with a PCIe connection. In these systems all PCIe connections are routed directly to the CPU. The UMI interface previously used by AMD for communicating with the FCH is replaced with a PCIe connection. Technically the processor can operate without
754-403: The release of the Zen architecture. Before then, only APUs used FCHs, while their other CPUs still used a northbridge and southbridge. The Fusion Controller Hubs are similar in function to Intel's Platform Controller Hub . AMD's FCH has been discontinued since the release of the Carrizo series of CPUs as it has been integrated into the same die as the rest of the CPU. However, since the release of
783-445: The remaining northbridge and southbridge functions into a single chip. Intel's version of this is the " Platform Controller Hub " (PCH) while AMD's version was called Fusion Controller Hub (FCH). The PCH is still called a chipset. This is an enhanced southbridge for the remaining peripherals—as traditional northbridge duties, such as memory controller, expansion bus (PCIe) interface and even on-board video controller, are integrated into
812-506: The switch to PowerPC , Apple used various ASIC suppliers for their chipsets such as VLSI technology, Texas Instruments , LSI Logic or Lucent Technologies (later known as Agere Systems ). When Apple switched to Intel they used traditional PC chipsets. In the 1980s, Chips and Technologies pioneered the manufacturing of chipsets for PC-compatible computers. Computer systems produced since then often share commonly used chipsets, even across widely disparate computing specialties. For example,
