    In the "Design News: Volume 8, Issue 19" newsletter you will see (a bit down the page, under "Qualification planned for dual-core processors, paving way to multicore" about the MPC8572E and MPC8641D dual core CPU's):

    "Note: a lower power, lower cost, pin-compatible variation of the MPC8641D ? called MPC8640D ? will be available July 2008. Contact your sales representative for more information."

    For quite some time I have dreamt about a computer based on a single core 8641D (that is - the version without the "D" ;-)), but perhaps a 8640 would make a better choice? It seems to offer the same SoC functions and controllers (dual DDR2 controllers, four Gigabit ethernet controllers, 2x PCI Express x1/x2/x4/x8, etc), but lower power and *lower cost*, so maybe it would be more interesting?

    Note: I'm not saying that anything of this is going to happen, only dreaming here. Genesi seems to be focusing on the 8610 and 5121e for now, but it is interesting technology nevertheless, and perhaps worth keeping an eye on for those interested in PPC CPU's...

    Anyway, if anyone finds out more about this processor I'd be happy if you post a link here! :-)
    MorphOS is Amiga done right! :-)
    MorphOS NG will be AROS done right! :-)

    As Karl posted on powerdeveloper.org:

    Freescale?s MPC8640D processor debuts as a lower power, lower cost version of the MPC8641D device

    Available in single or dual core versions, the MPC8640D delivers AltiVec processing and high performance for less

    AUSTIN, Texas, July 15, 2008 ? Freescale Semiconductor introduces the MPC8640D ? a lower cost, lower power version of the MPC8641D dual core processor. The device is available in single and dual core versions and is ideal for networking, telecom, pervasive computing, aerospace and defense applications.

    The MPC8640D enables customers to utilize high performance e600 Power Architecture? cores and AltiVec? 128-bit vector processing at lower price points and power requirements. The MPC8640D processor runs at 1.0/1.25 GHz per core while consuming up to 27 percent less power and costing up to 37 percent less than its MPC8641D predecessor

    Well, up to 27% less power consumption (and heat) and costing up to 37% less, this one is quite interesting IMHO. :-)

    Couple this chip with a AMD SB750 southbridge, and you could have a quite nice machine:

    - One (or two) e600 core with altivec running at 1.25GHz
    - PCI Express x16 slot for graphic cards (8 lanes connected)
    - 4 Gigabit Ethernet connectors
    - Up to 6 SATA 3.0 Gbit/s hard disk drives, with RAID 0, 1, 5, 0+1 support
    - eSATA
    - 1 IDE channel for HyperFlash module
    - Up to 14 USB ports (12 USB 2.0 and 2 USB 1.1)
    - HD Audio
    - Infrared receiver/transmitter port compatible with IrDA standards
    - Super I/O (not really needed with that many USB's?)

    Make it as a Micro-ATX motherboard. A perfect little developer desktop! :-)

    With the dual core version, you could even have two operating systems running at the same time! :-)

    From: West Palm Beac...
    I think the 8640 is really a refinement/replacement
    for the 8641 just as the 7448 was to be the enhancement to
    the 7447...unfortunately it had some early issues. Maybe
    we will see that this new revision is alot better... it almost sounds
    like a die shrink? just my 2 cents...
