While impressive from an engineering point of view (and a sheer "how badass can we get?" POV), the fact that they needed to use liquid helium to run the cpu at 7 GHz is more proof that we're heading for a massively multicore future - at least until another set of materials to replace silicon and aluminium gets in widespread use and which can run faster without getting hotter. I think we'll see 80-core x86 chips first, though.
And daqman - I can sympathize! I worked in a plasma physics lab in college, and we used a lot of liquid nitrogen and helium both, and while liquid nitrogen was fun (a colleague froze a slug at one point, and I took a thermos back to a party to pour into a punch-bowl, etc), the liquid helium was tough to work with. Not to mention time-consuming, since filling a dewar meant a *massive* amount of super-cold "fog" coming out of that flexible metal pipe from the big tank, and then air was always freezing onto the rim of the dewar (and I got some pink skin a few times, but never actual frostbite, doh!)
@Software_Goddess: I've been solidly in the AMD camp for many, many years myself. I've never been anti-Intel, but I always appreciated lower-cost alternatives who tried harder to innovate. I even used to build my own systems with Cyrix processors, back in the day. #amd7ghz
That's too bad because although I have an Athlon system at home, I still have to update my mobo to accept DDR2. And now that the Athlon is the SUV of CPUs as far as power consumption, I think I'll have to move over to Core or i7.
i have been toying with building a new rig and this gives me hope at doing it cheaply. i think my parents want a box they can put next to the tv as well. now do i have to overclock it to get good performance?
@Nick: No you dont i have the CPU that is a step below this one(see my post below) in a HTPC and it preforms great with no overclocking. And you can get a whole system up and going with a really nice videocard for about $500.
as i understand ceramic and its application on the shuttle -- it's not an insulator, but its properties associated with handling high temps and dissipation of that heat. so, like a heat sink. and it looks slick as snot. and just as green.
Actually you have it backwards. The shuttle's tiles are such great insulators that you can hold a red hot one in your hand without burning yourself. They are really poor conductors of heat. The heat sink idea was rejected due to the excessive weight required to dissipate the amount of heat generated during reentry.
Uhh... the ceramic materials used in military armor and the space shuttle are made to protect things from heat. They're some of the best heat _insulators_ in the world. In other words, pretty much the worst thing you could possibly use for a heatsink.
My guess is that ASUS is using an entirely different family of ceramic and this Giz poster just chose some poor examples.
@irish_stickman: Huh? I think I must have missed your point.
You always want computer parts to be as cool as possible, since it reduces errors and improves the lifetime of components involved. Just because it can work when it's hot doesn't mean it's a good idea.
@jdickson87: I think what he meant (but poorly explained) is that the ceramic is used to shield the rest of the board from the parts that get hot (CPU, heatsinks/pipes, etc.). Not sure if that is actually what they are trying to do with this board, but I think that is what he meant.
