The DTX form factor was announced to be in development by AMD on January 10, 2007. 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. They also present a shorter variant named Mini-DTX which is smaller in PCB size of 203 mm by 170 mm.^[1] Form factor refers to the linear dimensions and configuration of a device as distinguished from other measures of size (for example Gigabytes; a measure of storage size): in computing, form factor is used to describe the size and format of PC motherboards (see AT, ATX, BTX), but also of hard...

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
