This article compares the IBM compatible Personal computer Motherboard form factors – that is the different sizes and specific or de-facto standards of major system In the area of IBM compatible Personal computers the AT form factor referred to the dimensions and layout ( form factor) of the Motherboard for In the area of IBM compatible Personal computers the AT form factor referred to the dimensions and layout ( form factor) of the Motherboard for Enhancements Low-profile - With the push for ever-smaller systems a redesigned backplane that shaves inches off height requirements is a benefit to The ATX (for Advanced Technology Extended) form factor was created by Intel in 1995. LPX (Low Profile eXtension originally developed by Western Digital was a loosely defined Motherboard format ( Form factor) widely used in the 1990s NLX (New Low Profile Extended was a form factor proposed by Intel and developed jointly with IBM, DEC, and other vendors for low profile low cost mass-marketed microATX, also known as µATX (sometimes Transliterated as mATX or uATX on Online forums is a Small form factor standard FlexATX is a PC motherboard Form factor derived from ATX. The specification was released in 1999 by Intel as an addendum to the MicroATX The DTX Form factor was announced to be in development by AMD on January 10, 2007.

The DTX form factor was announced to be in development by AMD on January 10, 2007. Mini-ITX is a 17 x 17 cm (or 693 x 693 Inches) low-power Motherboard Form factor developed by VIA Technologies. Embedded Platform for Industrial Computing (EPIC is a computer Form factor standard put forth by a combined effort from WinSystems VersaLogic Octagon Systems Micro/sys Nano-ITX is a computer Motherboard form factor first proposed by VIA Technologies at CeBIT in March 2003, and implemented in late 2005 COM Express, a Computer-on-module (COM form factor is a highly integrated and compact PC that can be used in a design application much like an integrated circuit ETX, standing for Embedded Technology eXtended, is a highly integrated and compact (3 ETX, standing for Embedded Technology eXtended, is a highly integrated and compact (3 Pico-ITX is a PC Motherboard form factor announced by VIA Technologies in January 2007 and demonstrated later the same year at CeBIT. PC/104 (or PC104) is an Embedded computer standard controlled by the PC/104 Consortium which defines both a Form factor Mobile-ITX is the smallest x86 compliant Motherboard Form factor. Events 49 BC - Julius Caesar crosses the Rubicon, signaling the start of civil war. Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. It is for small form factor PCs (especially for HTPCs) with dimensions of 203 mm by 244 mm,[1] AMD stated that the DTX form factor is an open standard, and is backward compatible with ATX form factor cases. Small form factor ( SFF) computers are housed in smaller cases than typical Desktop computers While the term has no exact definition it generally includes A Home Theater PC ( HTPC) or media PC is a convergence device that combines the functions of a Personal computer and a Digital video recorder. The ATX (for Advanced Technology Extended) form factor was created by Intel in 1995. They also present a shorter variant named Mini-DTX which is smaller in PCB size of 203 mm by 170 mm. A printed circuit board, or PCB, is used to mechanically support and electrically connect Electronic components using conductive pathways or traces [1]
The specification provides for up to 2 expansion slots on a DTX motherboard, in the same position as the top two slots on an ATX or microATX board. microATX, also known as µATX (sometimes Transliterated as mATX or uATX on Online forums is a Small form factor standard Upcoming DTX boards will likely contain one PCI Express slot and one PCI slot. Not to be confused with PCI-X, a different bus architecture Peripheral Component Interconnect Express, officially abbreviated as PCI-E The Peripheral Component Interconnect, or PCI Standard (commonly PCI) specifies a Computer bus for attaching peripheral devices to a Computer The spec also provides for optional ExpressCard expansion slots on DTX motherboards. ExpressCard is a Hardware standard replacing PC cards (also known as PCMCIA cards both developed by the Personal Computer Memory Card International Association
Benefits
There are several benefits DTX provides to reduce production costs. [2]
- DTX will allow up to four motherboards – for low cost – per standard printed circuit board manufacturing panel sizes
- Mini-DTX will allow up to six motherboards – for low cost – per standard printed circuit board manufacturing panel sizes
- DTX motherboards can be manufactured in as few as four layers of printed circuit board wiring for motherboard cost savings
- By leveraging backward-compatibility with ATX infrastructure, vendors may gain a low-cost DTX product offering with little development expense
