Introducing BTX

Intel released news of their Pentium 4 570J just yesterday when they lifted the NDA (non-disclosure agreement) on it.  Check out our benchmarks here. Today, a day after they released their 3.8GHz Prescott, Intel lifts their NDA on the longed for details of their new BTX form factor.

At Computex this past summer the technology on the minds of the attendees was the new reengineered PC form factor that was said to change the way we look at desktop systems and the way they are to be cooled. As we mentioned in our June sneak peak of this new "Balanced Technology" there are many who are thinking twice about the performance benefits of the successor to ATX and how the public will gain from changing over to it. We also mentioned that there are some who believe this new design is just a way to help deal with the thermal problem with Intel's CPU's and that since Intel is the only name backing the technology the thermal issue is the main reason they really want to continue the push for BTX. At Computex the only BTX board on the floor was from Intel, which was not a surprise to us, but there were quite a few BTX cases from various companies including Enlight and AOpen.


Today, as Intel releases information on the BTX form factor with special evaluation kits, case manufacturers can begin designing cases to compliment Intel's motherboards, but does the industry want to follow?  Passions are running high against BTX; the thought of the big chip maker forcing yet another design change upon the industry has several people extremely upset.  We received a press kit from Intel with a microBTX motherboard and AOpen's newest desktop BTX case. 

We plan to take a middle of the pack Intel 915G microATX motherboard/chassis combination and compare it to the new Intel 915G microBTX motherboard/combination we received today.  We will test the microATX motherboard in a full ATX desktop case and a microATX tower.  Thermals, noise and size will dictate the majority of our conclusions in the analysis.

will intel even need btx anymore? since they are probably going to be dumping the p4 in favor of the pM(eventually)?
i thought one of the main reasons why btx was designed was to better handle the hotter p4 processors and to cool them more efficiently?

Am I reading this right... warm air from the CPU is exhausted out the FRONT of the case????

#5 that must be the canadian version, it'll keep us warm during winter by exhausting warm air into our faces.

God looking at those small cases makes me tremble and remember my parent's old IBM Pentium I system where you had to remove the PSU and the CD drive to install the RAM. I was so glad when I saw computers moving AWAY from this type of design...forget footprint, I want a case I can actually work in.

Either way, congrats to Intel on making a new Delleron case, but I'm simply not interested. Great for OEM's but useless for me, just like most of Intel's products...

As for #3's question, why does Intel need it outside of helping their OEM buddies? Dual core is only going to make Prescott's heat issues stand out further and their x20/30/40's on the roadmap still are clocked in the range where they are going to be high heat output. All that heat has to go somewhere...

BTX is obviously NOT a great design. Intel changes sockets, Mobo and other specs periodically to FORCE people to update to their latest crap. Don't expect a rush to BTX. It's another Intel spec unlikely to ever gain foothold...

For those who don't already know you can do wonders for ATX case cooling with "managed airflow". By actually directing incoming cool air to the heat sources and isolating the CPU fan from warm air in the case, no one really needs a BTX case and your PC will run much cooler with managed airflow.

While Intel definitely needs a tornado inside a box to cool their defective 90 nano CPUs, the BTX standard is just another Intel marketing scam for all practical purposes.

Just say NO !

To me, BTX looks like a winner for only one niche: small form factor business desktops. By that definition, I don't include Shuttle's wonderful SFF PC's which work best for home and HTPC enthusiasts. The microBTX form factor looks great for an office environment where quiet operation is a real plus, as well as power consumption, and since business PC's don't need to be cutting-edge, middle-end processors can be used that don't generate a lot of heat.
Tor the enthusiast however, BTX looks like a bust to me, more of an attempt by Intel to throw the market out of whack, specifically AMD's market. Enthusiasts already have case designs meant to exhaust a lot of air and keep systems cool. Many enthusiasts LIKE a little bit larger case so that they have more expansion room, with the exception of their HTPC, and so that they can house a decent power supply for that expansion.
I see HP, Compaq, IBM, and other mainstream business computing giants adopting BTX; it will probably do well in the business market as well as in mass retail, where OEMs would rather make a system with less fans to fail and at cheaper cost. That's a pretty big sector for profit of course, but this form factor, IMO, leaves PC enthusiasts out in the cold.

As always, so much Intel backlash, simply because, its Intel.

This is how cases should have been done originally. Align all the hot components and put a fan in front and behind them. Makes sense, right?

Current ATX design is "put a fan on every hot item you have". At least that's how my case is.
