    Jos oikein ymmärsin Notebookcheck.net sivuston arvostelusta niin arvostelun mukaan Samsungin RF711 kannettavassa olisi liian pieni muuntaja nähden kannettavan neliydin prosessoriin. Mutta voi tietysti olla että ymmärsin väärin. Voisikohan joku katsoa asiaa ja kertoa olenko ymmärtänyt oikein ?

    http://www.notebookcheck.net/Review-Samsung-RF711-S02DE-Notebook.52924.0.html

    Tässä kyseiset lauseet:

    We attempt to bring the Samsung RF711's temperatures to the limits with our simulated full load situation induced by Prime95 and Furmark. However, the cooling system manages the temperatures well. But we noticed that the notebook doesn't have its full potential in the stress test. The processor speed is throttled to almost 1.4 GHz when single cores are put under full load and stays there for the most part. The clock rate occasionally also reaches 1.5 GHz and very rarely the full 2 GHz. Thus, it's no surprise that the temperatures aren't a problem. The reason for this could be the overburdened power adapter (see section about power consumption).

    The power consumption during low load is agreeably low. The Samsung RF711 consumes 9.9 watts – 15.8 watts in idle and during very low office load. The energy saving mechanisms in the processor and Nvidia Optimus ensure very good rates here. The Samsung RF711 has a different side, though. When the hardware is really put under demand the consumption increases considerably. The maximum consumption fluctuates from 90.7 watts up to 103.6 watts. The included power adapter is however only specified for 90 watts. This is likely why the processor is throttled during full load.

    The only drawback is the performance throttling during full load. Performance is wasted by the obviously too small power adapter.

    Näinhän se menee. Eli prossu ei saa tarpeeks tehoo joten se toimii huomattavasti pienemmillä kellotaajuksilla, kun mihin se muuten pystys. Eli ei ole nii nopee, kun luvataan.

    tässä uusi muuntaja jos kiinnostaa, en tiedä missä myydään suomessa mutta silti www.coolermaster.co.uk/product.php?product_id=6645

    Justiisa. Minkälainen muuntaja on riittävä 4ydin prossuille ? Asuksen sivuilta löysin että Asuksen yhdes 4ydin prossu kannettavassa on 120 wattinen ja toisessa on 150. Notebookcheck sivuilla on kyllä paljon juttuja mutta en löytänyt tästä asiasta mitään, paitsi mitä tossa Samsung kannettavan arvostelussa on.

    Erikoiselta kuulostaa että Samsung myy kannettavaa joka ei toimi luvatulla nopeudella.
