Talk:Platform Controller Hub

Raw Information

Added

• Ibex Peak is renamed to PCH (Platform Controller Hub).
• Redesign is part the Intel 5 Series Chipset.
• The southbridge and northbridge are combined.
• PCH holds the display controller for motherboards with integrated graphics
• The controller for the graphics card is moved from the northbridge to the processor.
• The PCIe Graphics is connected to the processor instead of the north chipset.
• The memory controller moves to the processor.
• The connection to RAM is with the processor instead of the north chipset.
• PCH has two types of connections going to the processor:
  • An FDI (flexible display interface) for integrated graphics if the motherboard has it and
  • A DMI (Direct Media Interface) that used to be between the northbridge and southbridge chipset and is now between the PCH and the processor.

Information Left Out

• PCH chipsets have a package size of 27mm x 27mm.
• The PCH serves out LGA 1156 and LGA 1366 sockets.
• The PCH is a class of chipsets.
• Each chipset has a set of information that can be added. Example in italics (info from ark.intel.com)
  • Name: Intel BD82H55 PCH
  • Launch Date: Q1'10
  • Max TDP: 5.2 Watts
  • TCase: 111 C
  • Integrated Graphics: Yes or No
  • Supported Graphics Output Connection: HDMI, VGA, etc...
  • Cost in 1k Bulk: Cost

PCH is NOT part of Intel X58 chipset

The Intel X58 or Tylersburg IOH (I/O Hub; like an MCH minus the memory controller) connects to an ICH10 and not an Ibexpeak PCH. The PCH does connect directly to the Ironlake IMC (integrated memory controller) built into the lower-end mainstream mobile and desktop Nehalem processors. I removed the reference to Intel X58.

Introduction

The introduction starts: The Platform Controller Hub (PCH) is a family of Intel microchips. I/O Functions have been reassigned between the PCH, a new central hub, and the CPU.

This opening offering has a few flaws: It doesn't say what the PCH is. When it talks about reassigning functions, it assumes prior knowledge of what the PCH is. It introduces a mysterious central hub that never gets explained. 78.147.55.229 (talk) 15:41, 15 April 2012 (UTC)

What this page badly needs

The actual capabilities of the various PCHs. These are (for some reason) put in the pages about the cpu sockets, e.g. LGA 2011 has far more info about Patsburg than this page does, even though the PCH capabilities have little to do with the CPU socket (besides connecting to it via DMI etc.) Someone not using his real name (talk) 23:48, 20 January 2014 (UTC)
