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.

RE: A replacement for ATX would also be nice

I believe BTX is failing because it isn't backward-compatible with ATX and it offers no major improvements over ATX overall. It does offer better airflow, but nothing to make it standout.

Is it just me, or is AMD suddenly become the PC innovator. I know Intel has the awesome Core 2, but it doesn't offer new stuff. AMD made x86-64, AMD made integrated memory controller, AMD worked on Hyper Transport, AMD's Live seems to have all the momentum over Intel Viiv. And other things. AMD made a huge splash at CES.

It might just be you. If by "suddenly" you mean "recently", then Intel has been leading the charge. DX10-compatible integrated graphics (X3000), on-board flash for HDD access (Robson), 45nm, quad-core, dual quad-core, Centrino platform, Apple platform, performance-per-watt... I'm pretty sure the list goes on.

I think BTX is having trouble because it was released while Intel was basically getting owned by AMD. Enthusiasts and early adopters weren't buying Intel at the time, so why would they buy a new form factor for a product they don't own? It's ironic that now that Intel has taken a powerful lead, AMD is releasing a new form factor...

Intel has much more R&D than AMD:

Intergrated Memory controller:

The integrated microprocessor memory management unit (MMU) was developed by Childs et al. of Intel, and awarded US patent number 4,442,484.




AMD deserves credit for this, but the credit is equally shared amongst the entire HTX forum:

Advanced Micro Devices, Alliance Semiconductor, Apple Computer, Broadcom Corporation, Cisco Systems, NVIDIA, PMC-Sierra, Sun Microsystems, and Transmeta.

Also look up CSI for Intel's implementation of this.

AMD Live:

Like you said, Intel Viiv, which is better is a matter of opinion.

The rest you said is all opinion. And you might just want to do much more research on the Core 2.

Wonderful how sensitive (vote down with no response for why) AMD fanboys are that they light is not so bright. For gods sakes I own a AMD64 system if anyone cares.

This message was FOR Chillin ONLY & NOT FOR ANYBODY ELSE-
read post-it clearly implies that.
Only find it rated down-

This is just for the guy WHO ABUSES THE VOTING SYSTEM & or MISUSES IT.

*Ratings DONT bother me a bit,nor do I care about it.

*I dont make my comments for ratings,rather on what I think,know about the subject matter.In short my opinions.

*If you dont approve it -give a counter argument & NOT VOTE
ITS PLAIN COWARDLY-CREEPY-SLIMY of that person to hide behind the VOTING system.


*I waited for this opportunity to prove-how many of posters
making good/valid comments get voted down by a few who MISUSE the system,for CHEAP THRILLS.

*THIS is blatant ABUSE of the Voting/Rating system.



DT has picked some garbage on its way-DT better dump this garbage.

Well... to be honest I don't think it was a very good post and there is a misleading part which could deserve a down rating...



It misleads in two ways:
1 - It associates IA64 and EMT64, two very different architectures (although IA64 can run x86 code)
2 - It does not mention that it was AMD that developed the architecture. Intel only used AMD's architecture due to market pressure (namely MicroSoft) and because they can, due to cross license agreements. AMD deserves all the credit for "fixing" x86 (the new architecture makes a hole lot of improvements, correcting most of x86's major flaws).

Maybe you did know all of this... your post does not say anything contradicting what I said... but it was misleading... do you agree?

P.S. Disclaimer: I bought a lot of Intel stock and I'm hoping they make piles of money this year... Their stock is very undervalued for their position in the market.
