      On a more serious note, I think that it's impressive that AMD has turned it around in the temperature department while still delivering great performance. The AMD64's [amd.com] kick ass when you want them to, and then scale back to be cool when you aren't running processor-intensive aps. I'm sure Transmeta or someone else thought of doing something like that before, but I think that this is where we'll see it more and mroe often.

This method is a lot less complex than attempting to use 2 processors, one for high load and one for low load.

I'm typing this on a Athlon XP-M laptop right now and it actually stays quite cool until the CPU load goes above a certain point and it jumps fromm 533Mhz to 1.74GHz, at which point if its sustained it almost gets uncomfortable for laptop use.

He had an interesting proposal which I suspect is probably going to end up being used in nearly every architecture. The energy usage of a procesor is proportion to the square of the voltage - so dropping it as much as possible is desirable. The only problem is that once you get too close, you start getting bit level errors. He proposes to use a shadow register to keep track of values as they pass through and detect bit errors automatically, and route around them. If run at the optimal voltage (1.4 volts) a razored process will see a dramatic drop in energy consumption with a virtually-nonexistant hit to processing power.

      would increasing the size of the actual chip help any?

      It would --- but there would be other problems.

      The first one is the most simple: silicon's expensive. Really expensive. The more units you can slice off that wafer the cheaper the units are. Making the die bigger simply for thermal reasons isn't going to wash with the chip manufacturers. They already glue the die to a metal backing plate, which gives you much the same effect anyway.

      The second one, however, is the most crucial one. Electricity is slow. Electrical impulses travel at about 2/3 c through copper and a touch less through silicon (IIRC, I can't find the figures to check). This means that the bigger your die is, the longer it takes the impulses to travel from one side of it to the other.

      A 1GHz clock fires every 10^-9 seconds; since the speed of light is 3x10^8 m/s, this means that the impulses are going to travel about twenty centimetres between clock pulses. For a 4GHz clock, it'll be about 5cm. There's a lot more wiring than that folded up inside the die; and it gets worse --- particular things happen at particular times throughout the clock cycle, and where you are in the clock cycle now depends on how long the wire is that connects you to the clock. Making sure everything happens in sync is a nightmare.

      There are solutions to all of this; asynchronous designs which don't use clocks, offloading functionality to special-purpose processors like GPUs so you don't need as fast a main processor, radically different approaches like Cell, optical transports so you can route signals through each other, etc, but basically there are loads of good reasons why you need the die to be as small as humanly possible.

  • The dudes and Overleap are more concerned with the effects of sustained heat on the motherboard, particularly the capacitors which reduces significantly the functional life of the circuitry. They figures they use estimate that today's current crop of CPUs generate enough heat to reduce the life of the motherboard by half or to about 3 years on average. So regardless of what is happening to the operational performance of the unit from too much heat, what's true is that come hell or high water your machine wi

    Hotness is all about Intel's branding....

    Did you hear about the new hotness? Intel Pentium, SCORCHING PERFORMANCE! ssssssssss!

    Stick a Prescott on a long stick and apply that scortching brand on the rear end of any Longhorn cattle, and you've got yourself a stampede of sales, yeeeee-haw!

    I can't believe nobody has said this yet, but the absolute FIRST thing you should do if your system is running over-hot is check the airflow and direction of all of your fans.

    Most ATX cases like to have a fan blowing in the front, and other fans blowing out the back, check your case documentation. If one of your fans isn't working well, or is actually facing the wrong way, the entire airflow scheme goes straight to hell. I've seen this happen several times, but now that cooling is so critical incorrect fan placement is often a show-stopper.

    Today's story? My buddy builds a new system with a new P4 3.4HT. It exhibits classic signs of overheating-- the fan sounds like a 747 taking off all the time, odd beeping, memory errors, and when his brother who actually built it for him runs 3DMark, it scores something like 40% of what it should have on CPU. Everest [lavalys.com]says it's running at >80C. Much freaking out is done, and they order a hardcore Thermaltake fan to replace the standard/weak one that came bundled with the processor. That comes, and it helps somewhat, so the processor isn't stepping itself down to non-melting temperatures, hanging at 65-70C full-performance. Memory errors still a bit of an issue.

    So I come over to look at it. Dumbass neighbor (Best Buy Geek Squad employee/Frat Boy) had put the front fan on facing backward while assisting with the assembly, so the front 80mm case fan was blowing OUT of the case.

    I unscrewed the fan, flipped it around, and two minutes later the computer was playing Far Cry and humming along at 40C, by far the quietest computer in the room.

    Moral of the story? If you have a misplaced or broken fan, your cooling power drops massively. It pays to actually look at your case documentation now. Oh, and buy Antec [antec.com].
