    @randvegeta you’re comparing the most recent power saving tech with a scrap that should die long time ago. They are not able to go down with consumption at idle even close to the newest gens.

    Could you elaborate what you are saying? I kind of understand what you are implying but do not fully understand it.

    Older gen CPUs cannot regulate their power consumption based on load very much.
    Modern CPUs will, while idling, take very little power.

    Oh I see. Thx. :-)

    I have found that underclocking is generally more effective on older CPUs that newer ones.

    NEW CPUs do a good job at reducing power when idling compared to older CPUs. So I think my statement is even more true for older CPUs.

    But performance per watt absolutely stinks, especially compared to modern CPUs.

    Maybe it is me who are not very much concerned with a few (dozen) watts saving per CPU.
    I still am not much impressed with modern powerful CPUs, with one of which cost I can build a few (dozen!) servers (one with Dell R610, Dual 2.66/3.06 GHz with 12 cores, 64 gig ecc memory, 2X SAS 15K 160 gig drive, H700, etc, for example, the current one of mine except for the SSD disks).
