    read the costel post make me really happy with my choice of No More A-eon in My home...
    now i have a micro A1 the true real amigaone machine, the quad g5 the best powerpc desktop machine with the hope of morphos on it... and a threadripper 1950x that will make me happy emulating x5000

    Ugh, flawed Northbridge.
    A Pegasos II maybe, any early AmigaOne, no thanks.

    ...that wasn't allowed to be officially called an "AmigaOne" ;-)

    If you take the time to read his posting to the end you‘ll find that he writes he was sent a replacement by A-Eon in 2015.


    Yes, few years late when he was under heavy x5000 development or similar. This gap to task wait seems to be crucial since there seems to be no one else assigned to task.

    Let's face it, the situation is pathetic. The more I compare the X1000 to the X5000/20, the greater my appreciation for the former is.
    Not a bad little system.
    Not as powerful as a Quad G5, but still pretty cool.

    However, since we aren't likely to see MorphOS on an X1000 or a Quad G5...and things seem pretty terminal for big endian PPCs...it is what it is.

    PA Semi has awful MIPS per Mhz ratio degrading its 1.8Ghz nominal rating, but when used dual core, with FPU instructions, it has fast mem and SATA and board is quite expandable. Its bi-endian arhitecture, 64-bit, G5 class overall in all but integer performance. Too bad its not that easy to add support for another mobo with no financial stimulation (MorphOS). Its quite enjoyable under Linux, but sigh, change to Southern Island cards created no 3D problem under Linux, rendering many installations unusable incl. X1000 Ubuntu Remix sold by AEON. In the end there is no system that completely use it, and CFE is ... built for routers and should stay there.

    saga of wasted computer potential. So contrary to Amiga spirit of squeezing maximimum out of it.

    Yeah, but the system has a nice set of expansion slots backed up by more PCI-e channels.
    And the processor is slightly better than a G4 (as well as being full 64 bit).

    The more I'm learning about the X5000's expansion , the more troubled I am about it's limitations. Then again there's the difference in memory bandwidth.

    "Then again" or rather "furthermore"? ;-)

    Grammatically, you are right to point that out.
    But actually my final comment was a bit recursive.

    I am beginning to think the e5500 and e6500 cores may not be reaching anything close to their supposed memory bandwidth.

    If the cause of the memory performance issue is in the SoC, I think it's in the SoC's 'uncore' (memory controller) rather than its core.

    I'd like to see some bandwidth figures for the T10xx CPUs when interfaced with DDR4.
    The DDR3 controller used with other e5500 and e6500 cored CPUs does seem to be the issue.

    I thought the memory bandwidth and speed for the X1000's PA6T, was one of its few advantages, when compared to the older Apple G4 & G5 computers? Or is the PA6T an exception for e6500 cored CPU's, when it comes to memory bandwidth?

    It's probably that I'm not paying attention to this discussion, so I have made an incorrect assumption (again).

    Edit: I probably should have changed "memory bandwidth" above, to read/write speed to RAM.

    Yep, I think Andreas mentioned this before in response to a similar comment.
    The PA6T in the X1000 was produced by PA Semi and does not use a Freescale core.
    And yes, it's got better memory bandwidth then a G4 (not sure about the G5 though) as well as the e5500 and e6500 based Socs.

    So, even with older DDR2 memory, the X1000's memory controller performs much better than the X5000.
