AMD works on new small form factor standard

AMD today announced the company is developing a new small form factor standard. The new form factor, dubbed DTX, is AMD’s attempt to unify the various proprietary small form factors currently in use. DTX will be an open industry standard available to all case, motherboard and system manufacturers, but will not be limited to AMD-based products.

There will be two DTX standards available -- DTX and mini-DTX. The current DTX specification will only define a few requirements, the primary of which are motherboard mounting points and keep-out areas. Alternative specifications, like Micro-BTX, have strict guidelines for everything from airflow regulation to legacy I/O definitions.

AMD claims the consumer market needs a small form factor standard for the following reasons:
  • Electricity cost savings
  • Take up less space for both practical and aesthetic purposes
  • Enables systems that are quiet
  • Do not generate excessive heat
The enterprise clients need a small form factor for the following reasons:
  • Lower energy bills to help reduce operating costs
  • Enables differentiated and competitive solutions
  • Smaller, sleeker form factors take up less space in offices and cubicles and are designed to operate quietly
DTX falls between the current Micro-ATX and Mini-ITX standards. DTX motherboards will measure in at 200mm by 244mm compared to the 170mm by 170mm footprint of Mini-ITX motherboards. MicroATX motherboards measure 244mm by 244mm.

Mini-DTX will initially target sub-6 liter enclosures and support processors with TDPs up to 35 watts. The footprint of Mini-DTX motherboards will be 200mm x 170mm -- just a tad wider than Mini-ITX motherboards.

While there are already plenty of other standards on the market such as ATX, Mini-ITX and BTX, AMD’s goal with DTX is greater flexibility and lower costs. Greater flexibility is achieved by making DTX motherboards backwards-compatible with ATX and Micro-ATX.  Lower costs will be addressed with DTX due to the clever sizing of DTX motherboards. Most manufacturers are able to produce two standard ATX motherboard PCBs per PCB panel, a manufacturer can now cut four DTX or six Mini-DTX motherboards from the same panel.

There will be room for two expansion slots on DTX motherboards. No constraints have been set for the expansion slot configuration, which leaves manufacturers to decide which slots are needed. An ExpressCard expansion slot is also planned for the DTX form factor.

Expect AMD to release the final DTX specification later this quarter. It is unknown when or if manufacturers will produce systems and components based around the DTX standard, but several motherboard and enclosure manufacturers have already announced DTX products will appear in their 2007 roadmaps.

the arguments for the need for DTX in the market (which already has uBTX and pBTX) are week.

realistically amd should just embrace u/p BTX both are good standards, but are stuck in a bit of a chicken and egg market...

no one wants to buy btx mobos since the selection of mobos and corresponding cases is limited... and the selection of cases is limited since no one wants to build them until there is a well established market...

backwards compatability is a start, but is it much better than pBTX which is a pretty nice standard for highly dense, quiet and cool pcs.

so now we have 2 alternative (and improved) formfactors next to ATX,

nice, almost as nice as having both hddvd and blueray in the market.

whats best for all of us is consolidation of our nextgen form factor.

Companies always have and always will do what's best for themselves and their stockholders first, and only what's best for the customers if it happens to be the same thing. It's called capitalism, what you're talking about is the theoretical ideal of communism.

The problems with BTX are that it's proprietary, it has pretty stringent layout requirements and it's not backwards-compatible. Making a BTX-compliant AMD motherboard is quite problematic, too, since the DIMMs cannot be placed next to the northbridge.

The benefits of DTX are that it is royalty-free, it allows manufacturers to make their own motherboards however the hell they want to and it allows anyone with any ATX/mini-ATX/DTX case to make a system out of it. Then there's also the fact that these motherboards WILL be significantly cheaper to manufacture.

If a DTX motherboard with something like 4 SATA ports and a couple of USB headers (so 4 USB 2.0 ports) comes out I can just see myself getting rid of my big and noisy computer for DTX, especially if DTX cases are not insanely overpriced.
