AMD's Turion 64 on the Desktop

Posted by ryuzaki0 on from the building-it-out dept.

Toasty16 writes "SPCR has an overview of using an AMD Turion 64 mobile processor in a desktop system. There's a good bit of info about motherboard compatibility and power consumption as compared to a Pentium M processor. There's also links to articles from the Techreport and LaptopLogic on the same topic. If you've been thinking about building a low power HTPC or file server, mobile processor on desktop is an interesting option."

    I've been using Mobile Athlon XPs for a couple years now. Picked it up on the premise that they ran cooler, on lower voltages, and didn't have a multiplier cap. Worked wonders for hitting an 800MHz overclock on air (2.0 to 2.8). They also seem to work in all the mobos i tried, although some needed a BIOS flash.

    Honesty may be the best policy, but by process of elimination, dishonesty is the second best policy.

    Modern video cards accelerate a decent portion of MPEG-2 playback, but you still need a decent amount of CPU.

    I think with the most recent video cards, it's something like 50/50.

    Note: I'm not counting hardware resolution scaling here. Output scaling is one aspect of video playback that is historically EXTREMELY CPU-hungry, but has been supported in hardware on any video card made in the past decade or more. Even with hardware scaling, you need a 2-3 GHz+ CPU to play back high def MPEG-2, and additional HW acceleration (IDCT, MoComp) offloads 20-30% at best. VIA's video chipsets offload much more of MPEG-2 playback than most other video cards, but until the CN400 series, they were only able to offload standard def content. (90% of hardware MPEG decoders on the market only support MPEG-2 MP@ML, i.e. standard def content. MP@HL decoders for high def content are rare and expensive.)

  3. Replaced my servers for this reason.. by xtal · · Score: 5, Informative

    I was running two very old machines for fileservering and routing/firewall duties. My estimate put these machines at about ~$30-40/mo to run depending on what I was doing. I was able to drop this down by about half moving to a mini ITX board with the via C3 processor, and it only cost about $150. I could have spent less, but I upgraded the power supplies as well.

    You can easily measure how much power your computer draws with a multimeter from the hardware store - last time I was there I saw them for about $10. Put the meter on the AC amps scale, make sure the wires are plugged into the amp reading ports, and then wire it in series with your computer.

    I guarantee you'll be suprised. I was.

      Don't forget, what you're measuring is apparent power, which is really volt-amps. Computer power supplies have a significant power factor, so what you really want to do is measure the corrected real power which is in watts.

      Go to ThinkGeek and pick up a Kill-A-Watt, which will not only tell you how many watts your computer actually consumes, but also things like power-factor and kilowatt-hours, which is a much more accurate measure of power consumption.

  4. You can use cpufreq under linux instead. by ponos · · Score: 4, Informative
    I'm currently running my Athlon64 3200+ at 1GHz (VCore also lowered by a significant amount). The clock frequency never jumps above 1000 while I'm writing text, browsing, listening to MP3s (or all of these together). As a matter of fact, you need to really pound the machine to force it to go above 1GHz. The power consumption is very very low and the CPU temperature is almost equal to the case temperature (should be less than 40C for the CPU right now).

    Installing and running cpufreq is relatively easy and the savings are considerable. For newbie linux users I have an explanatory step-by-step post http://pkt3141592.blogspot.com/2005/07/fun-with-li nux-cpufreq-driver.html on the subject in my (almost abandoned) blog.

    Running a Turion is a hard-core option, but PowerNow should be enabled in ALL Athlon64 desktops.
