Battle of the Mobile CPUs: Core Duo vs Pentium M

CPU by piotke @ 2006-06-22

The Pentium Mobile line of processors has become quite popular with hardware enthusiasts as they offer a better performance per Mhz than their desktop companions. We compare Intel?s Core Duo for mobiles to their Pentium M, overclocking them on a desktop system they go head to head.

Test platforms & Methodology

Dothan Platform


Dothan Test Setup

Madshrimps (c)
CPU Intel Pentium M 740 (Dothan - 1733 Mhz - 533 fsb - 2 Mb)
With Asus CT 479
Cooled by Zalman CNPS9500
Mainboard Asus P4GPL-X
Memory 2*512 Mb DDR ADATA Vitesta DDR600
Other
  • XFX 7600 GT
  • Silverstone Zeus 750 Watt PSU
  • Nec 2050 DVD writer
  • 2x Seagate 200Gb SATA


    • One of the few motherboards that has a PCIe port and supports the CT-479 converter is the Asus P4GL-X:

  • Intel 915PL Chipset
  • PCIe 16x
  • Gigabit lan
  • 4 SATA ports
  • 7.1 surround
  • More information about the Motherboard

    Yonah Platform



    Yonah Test Setup

    Madshrimps (c)
    CPU Intel T2600 Core Duo (Yonah - 2166 Mhz - 667 Fsb - 2 Mb)
    Cooled by Thermalright XP-90C
    Mainboard Aopen i975X a-YDG
    Memory 2*512 Mb DDR2 OCZ PC6400
    Other
  • XFX 7600 GT
  • Silverstone Zeus 750 Watt PSU
  • Nec 2050 DVD writer
  • 2x Seagate 200Gb SATA


    • This AOpen board is also feature rich:

  • Intel 975X Shipset
  • DDR2 support
  • 2 x PCIe 16x slots, crossfire ready
  • 3 IDE ports (Raid possible) + 4 SATA ports
  • Azalia surround
  • Gigabit lan
  • Firewire
  • IR remote is bundled with the box.
  • More information about the Aopen motherboard


    Test configurations

    Both CPUs are quite overclock friendly and their default clocks speed is nowhere near their maximum limit. With air cooling they can be overclocked easily as the Yonah reached 3.2Ghz and was completely stable. We must admit though that we were lucky with the Yonah (Core Duo) as most units have a FSB wall, they simply refuse to work past a certain FSB no matter how much vcore you provide. Only with extreme cooling you can hope to get a bit higher.

    So here are the test configurations for each platform

    Dothan @ 1.73Ghz
    CPU Settings: 13*133 (default speed)
    Memory Settings: 133 - 2,5 3 3 6
    CPU voltage: 1,35 Vcore

    Dothan @ 2.6Ghz
    CPU Settings: 13*200
    Memory Settings: 200 - 2,5 3 3 6
    CPU voltage: 1,45 Vcore

    Yonah @ 2.16Ghz
    CPU Settings: 13*166 (default speed)
    Memory Settings: 276 - 5 5 5 10
    CPU voltage: 1,4 Vcore

    Yonah @ 2.6Ghz
    CPU Settings: 13*200
    Memory Settings: 333 - 5 5 5 10
    CPU voltage: 1,4 Vcore

    Yonah @ 3.2Ghz
    CPU Settings: 13*245
    Memory Settings: 408 - 5 5 5 10
    CPU voltage: 1,6 Vcore
