Socket Adapter Brings Pentium M to Desktop

EconolineCrush writes "Intel's Pentium M processor is widely regarded as the company's most compelling chip, and although desktop versions of it won't be available until next year, a new adapter from Asus allows users to run a Pentium M on existing Socket 478 motherboards. When coupled with a compatible motherboard, the CT-479 adapter is much cheaper than existing Pentium M desktop platforms, and also offers better performance by allowing the processor access to dual-channel memory configurations. Considering the Pentium M's frugal power consumption and great clock-for-clock performance, this could be an interesting upgrade for those looking for a low-noise system."

  2. Next logical step for quiet PC's. by Sv-Manowar · · Score: 5, Interesting

    I've always wondered about the potential of today's mobile cpu's as quiet/silent & power efficient replacements for the current crop of desktop processors. It'll be interesting to see how Intel react to this, and if enough people make use of these adapters to noticably affect P-M sales. After reading articles about silent PC's, and the various steps/careful hardware choice required to create them, its only logical to move to components where the cooling & noise issues have already been considered in the component design.

      I use a Powerbook, and I'd pretty much suggest the same thing myself.. that most people looking for a quiet pc would be far better served with a laptop of some kind instead (not to mention the numerous benefits of laptops combined with wifi etc). However moving well-thought out, power conserving chips from the laptop to the desktop can only be a step forward for desktops in general, and a crucial change of direction from the bigger-is-better P4 Extreme Edition style upgrades that have been delivered in the last few years.

      Laptop screens are not friendly to gaming.
      Laptop RAM capabilities are usually limited at 1GB or 2GB.
      Laptop CPUs cannot generally be upgraded.

      Those are probably the big reasons.

      Several reasons: 1. Desktops are less expensive for the same amount of CPU horsepower. 2. RAM, hard drives, opticals are all faster and less expensive. 3. Desktops are easy to fix if something breaks- parts are standard (except for some Mac parts.) Laptops are all proprietary. A $30 CD drive will cost $200 to replace.

  3. PentiumM in desktop vs Mobile Barton in desktop by non-poster · · Score: 5, Insightful

    So, I've been running a AMD Mobile Athlon XP Barton (link) in my desktop for about a year, in a standard Socket A motherboard (NForce2 based). It is easily overclockable, and runs cooler than my previous main CPU, an Athlon XP 1800.

    Is the PentiumM that much better, or is it just the CPU du jour?

  6. How about a more scalable solution? by NRAdude · · Score: 4, Interesting

    Does anyone know about those neat 386-based computer systems that install into your motherboard's unused DIMM sockets? Has anyone seen the Sun or Apple alternative x86 solution whereas a complete computer is assembled into a PCI adaptor form-factor and installed into a PCI slot to give access to a x86 nativity?

    We need more of these solutions. Just for the utility of it, I want a computer for general purpose use; consider a Transmeta solution, and then have a Pentium M co-processor that I can enable or disable when I need it to boost an application, or even better a Hitachi SuperH 128bit solution for quicker and greater math precision. I'm waiting for the days to return when computers were modular, separate FPUs from the die core for example, like back in the late 80's when the manufacturer gave you the manual that has all the BIOS function calls and circuit schematic in such an open manner.

    All I see today is a bunch of unnecessary IC bloat, taking advantage of increasing transistor efficieny to use more transistors and obtusely dissipate more heat with a design that is bigger than the previous. Is progress to obsolete computers or give what is needed? I would settle for a fab-shrunk 8-way computer based on the earlier technology because it worked. Where are all those great designs going to, or is it just a fighting statistic? How about a 386 PDA? Anyone seen one yet?

      The Amiga had such a board way back when, a generic CPU emulator that used FPGAs to emulate multiple processors. It could supposedly emulate a Mac faster than a real Mac (probably using the Amiga's CPU, though). They were still trying to get 486 emulation debugged last I heard, many moons ago.

  10. Northbridges... by evilviper · · Score: 4, Informative

    While it's nice to get a lower-power CPU, your results aren't going to be very impressive. The fact is, northbridges are also very power-hungry, and using the northbridge for a P4 with a Pentium M will certainly not give very good results. You really need a motherboard designed for the Pentium-M to get a low-power system, otherwise you'll just be wasting watts, and making a lot of heat for no reason.

    It seems nobody ever talks about the Northbridge, which, IMHO, will over-take the CPU, within a year, as the hottest component in a computer. If you take a year-old system, and put all the components (CPU/RAM) in a brand-new motherboard, you'll see the power consumption go up 10-20 watts. Why do you think they are now requiring fans on many of them? Even the motherboards that don't have one, commonly NEED one. They just leave it off because they know people don't buy motherboards with fans on the northbridge.

    They just assume case airflow with be enough to keep the northbridge within spec, which is rarely true. Many people with unstable systems may assume it's a CPU or software problem, while pointing a fan at the northbridge heatsink may be all they need to do to solve the problem. I have some Asus and MSI motherboards that are guilty of this (SiS and VIA chipsets).

    What pisses me off (personally) is that repeated requests to Asus, MSI, VIA and SiS for power specs on their chipsets/motherboards have been completely ignored. For that reason, I have kept using my old systems (brand-new Asus motherboard wasting space in my closet) and will not upgrade until I can find specs on motherboards (idle/load) before I buy them.

  11. I tried it by vadim_t · · Score: 4, Informative

    It costs about $50, and comes with the adapter, heatsink and fan.

    How good is it? I have no idea, since I broke a pin on it while trying to get it to work.

    Here's a warning to everybody thinking of trying it: The adapter is held in the motherboard's CPU socket only by the locking mechanism. The design makes it quite easy to apply pressure in such a way that it will rip the adapter off the motherboard's socket.

    For some reason, the instructions go like this:
    Insert adapter, insert CPU, lock CPU with screw, add heatsink. But I found that it's very uncomfortable, and risky. Be really careful when doing that, especially while installing the heatsink.

    On the next time I'll probably do it differently: insert the CPU into the adapter, lock it, then insert the adapter into the motherboard and add the heatsink.

    I broke it because I thought I was applying too much force while trying to fix the CPU and didn't turn the screw far enough. After removing and inserting the adapter several times I finally realized I didn't turn it all the way, but that must be when I bent the pin.
