  1. Re:Doing the math on Transmeta's New Smaller, Faster Chips Announced · · Score: 1

    My error was
    a) You have losses with ac/dc conversion (at least 25%)
    b) You have to support the electronics
    and
    MOST IMPORTANTLY
    its lumen/Watt, not cd/Watt.
    cd is intensity per square radian, so a laserpointer would have a few thousand cd/watt in its beamline and 0 everywhere else.
    Because modern lcds have a very wide field of vision, you would need to integrate of the whole hemisphere to get the real efficiency.(which isnt that easy)

    Memory power requirements are forgettable.
    Or have you ever seen Ram or 2.5"discs in notebooks with fans? No? Guess why...
    If you arent using your "corsair golden eagle fishing thuna blabla 500 ultra pro" overclocker Ram, you can get away with 1-3 Watt for 512 MB RAM in a notebook. At least with 266 Mhz ddr and 256mbit chips.
    And modern harddiscs are quite inexpensive, powerwise. Heck, even normal Desktop Drives are rated at about 6-7 Watt. Laptop drives optimized for low power are more likely to use a third of that.

    What you fail to recognice is the Screen as single most demanding component besides the cpu. People want bigger and brighter screens, and to create photons you need power. You cant just do a die-shrink like with ram or cpus to reduce the power requirements, you have to live with them. You can get 60 Lumen/W from your flouroszent illumination (but only on your happy day), you block 2/3 of it because you need colour filters, and another 1/3 because absorbtion/ect,and more for the space between the pixels, ect, and you have 10 cd/watt output at most.(in reality it should be even worst. Wall-plug->eye efficiency could be as low as 2-3 cd/watt)
    And people like displays with at least 100cd/m^2 because else its unreadable in bright daylight outside.
    DO the math....

    Dont underestimate the power requirements of the Pentium M.
    Yes, its a lot friendlier than all other "big" cpus, but if you use a lot of cpu-power, it still needs >25Watt. Thats a lot more than the whole rest of the system (ok, not if you are dvd-burning while using your mobile geforece 5700 to play doom3 on your 17" widescreen high brighness lcd, but you get the point...)
    Of course most of the time you dont need full-power, but still when idling it uses 5-7 Watt, more than the Transmeta with 100% load.

    The only problem is that the transmetas have limited performance. While pentium M can deliver in peak situation (but with a lot of power), the transmeta cannot.

    And your numbers are from soviet russia, arent they? (IAW: bullshit)

    10-20W would be a normal desktop board. 3-8 watt for normal Laptop(with ram, but without fance gfx).
    10 Watt for a hd is normal for a 10000rpm 3.5" disc. A 2.5" laptop disc is more likely to use 1.5-3 Watt, if its running at all.
    And 20-30 Watt would be a bad 15" or a very good 17" Lcd monitor with 200+ cd/m^2. For a 15" high brightness destop replacement Notebook, 15 Watt, perhaps 20 watt with max brightness.
    But your "long running" subnotebook with 10.4" 75cd/m^2 screen wont use much more than 5-7 Watt.

    a fire is good for a few papers, but not if you have a lot of paper in neat stacks.
    A few years ago i burned around 10KG of old records (they were on some kind of ultra thin paper that made shredding a pain in the ass).
    It burned quite well, than smoldered and went out. the next day i went through the ashes and there were whole piles that werent burned at all. Paper can be quite a good insulation, and the heat of the fire quickly goes up, not touching the heavy paper stacks at the botton of the light ash.

    In the end, it was a really big mess to clean up (i wanted to wash the ash away with water->lots of drenched paper...), so i bought a better shredder.

    Do you read?
    Yes, smaller platters reduce seek time.
    Yes, even the newer 3.5" cheetas only use 2.7" or so platters.
    But they keep a high internal radius. And they keep the same big case which leaves enough space for the big actuator magnets whichout them affecting the disc.

    In ultrasmall drives, you get a smaller platter size. But the internal regiens have VERY litte data per track, meaning a random search is much likly to cower grater parts of the platter than with "larger" discs.
    You just get less data per "head moving distance"
    Also, the low rpm create a lot of latency that is intependent of platter size: 5000rmp mean 6ms rotation latency PLUS the seek latency. Thats more than a 15rpm cheeta has in total.
    You cant easily spin the small drives higher because
    a) it hard to fit such a high speed motor in the few mm^3 available.
    b) power consumption
    c) heat (you get very little surface on the package and usually NO airflow.

    Combine that with the slower actuators, you get seek times slightly worse than a normal hd, rotation latencies that are a lot higher and of course less performance...

    ????
    Could you explain wtf this has to do with access time?
    If you can track to a film with audio sync or not is purely dependent on the container and the audio codec. Ogg or avi mit vbr mp3 can create problems, seek times dont (your blockindey is already in hd-cache, and if you dont jump into an i frame, decoding a lot of b/p frames (up to 11 in mpeg2 up to 100s in mpeg4) will take a lot longer than seek time.

    But even if seek time would be important for that stuff: Your 0.85" hd will have a lot worse seek time than any normal 3.5" drive. Because of the simple fact that you cant fit very powerfull magnets / coils in such a small package.
    If your reasoning would be true, we would have servers running of microdrive raids for years...
