Intel's BTX Form Factor Launched Today 201
Hack Jandy writes "It's been almost three years in the making, but Intel's BTX form factor finally has some retail products to show for itself. Anandtech has some extremely thorough benchmarks of the new technology and proves that BTX definitely shows an improvement over ATX for the same sized chassis. Anand claims BTX as a design win, "It's obvious why Intel waited for Monday morning to lift their BTX platform - they have a winner on their hands.""

"I've spoken with several sources here on the show floor from motherboard and enclosure makers who have all said the same thing: the BTX form factor is a non-starter on AMD systems. The problem seems to be the relative CPU and DIMM placement; the standard requires placement of DIMM sockets too far from the processor. With the Athlon 64's integrated memory controller, following the BTX spec becomes very difficult. Of course, BTX is Intel's spec, but it is also a proposed industry standard. Motherboard and enclosure makers are worrying out loud about the inventory control and design problems that may be caused by the extended coexistence of the ATX and BTX standards."

I don't see why AMD would want to do Intel's homework form, especially after Intel has done this to AMD-64. But making it an open standard and not preventing Intel from developing competing, compatible systems would be OK. I doubt if they develop a new form factor that they'd do this, either, but you never know.
As long as the PSU requirements are the same, and they'll fit whatever case I buy, I don't think it matters a whole lot where they place components on the motherboard, as long as it works from the standpoint of their own engineering requirements.
Trying to make compromises so that mobo layouts are identical between AMD-64 and Intel systems is bound to be non-optimal for both, and is thus a pretty pointless endeavor, and thus almost guaranteed to be on the market in the next 12-18 months.

Re:a winner? (Score:4, Interesting)
Good point. To add: The new BTX for allows for supposed better cooling because of the arrangement of components on the board. However how much of that extra cooling is due to the new CPU fan orientation.
Currently most fans are mounted so that air flow is perpendicular to the board. So cases need additional fans to move air parallel to the board (intake and exhaust). There are some CPU fans like the Jet [compgeeks.com]that are mounted the same way the new BTX fans are mounted.
This isn't new or innovative. Sun has mounted their CPU fans like this for years and even designed their computer so that there is a channel of air for just the CPUs. The Apple G5s and iMac G5 are also designed this way. With BTX there is the parallel flow but no channel so I would not assume that the cooling is as effective.

This is necessary... (Score:4, Insightful)
Anyhow, the locations for air intake and output are pretty close to standard, but manufacturers aren't taking advantage of it. CPUs and memory aren't put on a motherboard so they will be in-line with the air intake, and being cooled by the rear exhaust fans, or power supply fan. Instead, it's a hack-fest, with a bunch of fans inside the case, blowing hot air in circles, and hoping the case fans are 10xs more massive then they should need to be, to replenish the whole case with cool air every few seconds.
You can take certain steps on your own, like ducting air from the intake, directly to your CPU, which will cool things down IMMENSELY, but will not help with your RAM, Videocard, etc., which need proper cooling as well.
If you look at old DEC systems, you'll see they already had the cooling thing down to an art. 3 thermal zones, with very slow, quiet, thermo-controlled 80mm fans. They weren't ATX systems, however, and nobody adapted those ideas to PCs.
So, while ATX can be pretty effecient, it isn't happening. If it takes a whole new form-factor to force manufacturers to get it done correctly, then I'm certainly willing to switch. BTX isn't ideal, but it's a big step up.
And you can't say it's only Intel's problem. All processors put off a lot of heat, and with ATX you have to have several very loud fans just to fight against the heat. A better design means cooler, and quieter, whatever processor you use. Sure, maybe Intel will have to ignore the BTX specs on motherboard design where it will hurt them, but that's nothing new. ATX specified that power supply fans should blow air in, not out, but most everyone just ignored that, too.
