The PCH architecture supersedes Intel's previous Hub Architecture, with its design addressing the eventual problematic performance bottleneck between the processor and the motherboard. Under the Hub Architecture, a motherboard would have a two piece chipset consisting of a northbridge chip and a southbridge chip. Over time, the speed of CPUs kept increasing but the bandwidth of the front-side bus (FSB) (connection between the CPU and the motherboard) did not, resulting in a performance bottleneck.{{cite web|url=http://www.technewsworld.com/story/31594.html|title=Breaking the Speed Barrier: The Frontside Bus Bottleneck|last=Hook|first=Brian|date=17 September 2003 |publisher=Technewsworld|access-date=1 February 2016}}

As a solution to the bottleneck, several functions belonging to the traditional northbridge and southbridge chipsets were rearranged. The northbridge and its functions are now eliminated completely: The memory controller, PCI Express lanes for expansion cards and other northbridge functions are now incorporated into the CPU die as a system agent (Intel) or packaged in the processor on an I/O die (AMD Zen 2).

The PCH then incorporates a few of the remaining northbridge functions (e.g. clocking) in addition to all of the southbridge's functions, replacing it. The system clock was previously a connection to a dedicated chip but is now incorporated into the PCH. Two different connections exist between the PCH and the CPU: Flexible Display Interface (FDI) and Direct Media Interface (DMI). The FDI is used only when the chipset requires supporting a processor with integrated graphics. The Intel Management Engine was also moved to the PCH starting with the Nehalem processors and 5-Series chipsets. AMD's chipsets instead use several PCIe lanes to connect with the CPU while also providing their own PCIe lanes, which are also provided by the processor itself.{{Cite web|url=https://www.anandtech.com/show/15121/the-amd-trx40-motherboard-overview-|title=The AMD TRX40 Motherboard Overview: 12 New Motherboards Analyzed|first=Gavin|last=Bonshor|website=www.anandtech.com}}{{Cite web|url=https://www.gamersnexus.net/guides/3482-amd-x570-vs-x470-x370-chipset-comparison|title=AMD X570 vs. X470, X370 Chipset Comparison, Lanes, Specs, & Differences|first=Steve|last=Burke|website=www.gamersnexus.net}} The chipset also contains the Nonvolatile BIOS memory.

With the northbridge functions integrated to the CPU, much of the bandwidth needed for chipsets is now relieved.

This style began in Nehalem and will remain for the foreseeable future, through Cannon Lake.

Beginning with ultra-low-power Haswells and continuing with mobile Skylake processors, Intel incorporated the southbridge IO controllers into the CPU package, eliminating the PCH for a system in package (SOP) design with two dies; the larger die being the CPU die, the smaller die being the PCH die.{{Cite web|url=https://www.anandtech.com/show/8814/intel-releases-broadwell-u-new-skus-up-to-48-eus-and-iris-6100|title=Intel Releases Broadwell-U: New SKUs, up to 48 EUs and Iris 6100|first=Ian|last=Cutress|website=www.anandtech.com}} Rather than DMI, these SOPs directly expose PCIe lanes, as well as SATA, USB, and HDA lines from integrated controllers, and SPI/I²C/UART/GPIO lines for sensors. Like PCH-compatible CPUs, they continue to expose DisplayPort, RAM, and SMBus lines. However, a fully integrated voltage regulator will be absent until Cannon Lake.{{update inline|date=January 2019}}

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.{{cite web | url=https://www.anandtech.com/show/8995/amd-at-isscc-2015-carrizo-and-excavator-details | title=AMD at ISSCC 2015: Carrizo and Excavator Details }} However, since 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.{{cite web | url=https://www.anandtech.com/show/17585/amd-zen-4-ryzen-9-7950x-and-ryzen-5-7600x-review-retaking-the-high-end/4 | title=AMD Zen 4 Ryzen 9 7950X and Ryzen 5 7600X Review: Retaking the High-End }} The UMI interface previously used by AMD for communicating with the FCH is replaced with a PCIe connection. Technically the processor can operate without a chipset; it only continues to be present for interfacing with low speed I/O.{{cite web | url=https://www.anandtech.com/show/11170/the-amd-zen-and-ryzen-7-review-a-deep-dive-on-1800x-1700x-and-1700/13 | title=The AMD Zen and Ryzen 7 Review: A Deep Dive on 1800X, 1700X and 1700 }}

AMD server and laptop CPUs adopt a self contained system on chip (SoC) design instead which doesn't require a chipset.{{Cite web |title=4th Gen AMD EPYC Processor Architecture |url=https://www.amd.com/content/dam/amd/en/documents/products/epyc/4th-gen-amd-epyc-processor-architecture-whitepaper.pdf |access-date=2024-11-03 |website=AMD}}{{Cite web |last=Kennedy |first=Patrick |date=2019-04-08 |title=Supermicro M11SDV-4C-LN4F Review mITX AMD EPYC 3151 Platform |url=https://www.servethehome.com/supermicro-m11sdv-4c-ln4f-review-mitx-amd-epyc-3151-platform/4/ |access-date=2024-08-18 |website=ServeTheHome |language=en-US}}{{Cite web |last=Cutress |first=Andrei Frumusanu, Dr Ian |title=AMD 3rd Gen EPYC Milan Review: A Peak vs Per Core Performance Balance |url=https://www.anandtech.com/show/16529/amd-epyc-milan-review |access-date=2024-08-18 |website=www.anandtech.com}}

{{Update|section|inaccurate=y|date=December 2012}}

In the first month after Cougar Point's release, January 2011, Intel posted a press release stating a design error had been discovered. Specifically, a transistor in the 3 Gbit/s PLL clocking tree was receiving too high voltage. The projected result was a 5–15% failure rate within three years of 3 Gbit/s SATA ports, commonly used for storage devices such as hard drives and optical drives. The bug was present in revision B2 of the chipsets, and was fixed with B3. Z68 did not have this bug, since the B2 revision for it was never released. 6 Gbit/s ports were not affected. This bug was especially a problem with the H61 chipset, which only had 3 Gbit/s SATA ports. Through OEMs, Intel plans to repair or replace all affected products at a cost of $700 million.{{Citation |title=Intel Identifies Chipset Design Error, Implementing Solution|publisher=Intel |date=31 January 2011 |url=http://newsroom.intel.com/community/intel_newsroom/blog/2011/01/31/intel-identifies-chipset-design-error-implementing-solution}}{{Citation |title=The Source of Intel's Cougar Point SATA Bug|publisher=AnandTech |date=31 January 2011 |url=http://www.anandtech.com/show/4143/the-source-of-intels-cougar-point-sata-bug}}

Nearly all produced motherboards using Cougar Point chipsets were designed to handle Sandy Bridge, and later Ivy Bridge, processors. ASRock produced one motherboard for LGA 1156 processors, based on P67 chipset, the P67 Transformer. It exclusively supports Lynnfield Core i5/i7 and Xeon processors, using LGA 1156 socket. After revision B2 of Cougar Point chipsets was recalled, ASRock decided not to update the P67 Transformer motherboard, and was discontinued. Some small Chinese manufacturers are producing LGA 1156 motherboards with H61 chipset.
