    Interesting. Thanks for info.

    AFAIR he proclaimed that TD64 was a bug. I think he wouldn't probably dare to say the bad 'M' word in public ;-)

    The Sam that was released 7 years after the Peg2 is the Sam460ex. If we compare the CPUs (1.15 GHz PPC460EX vs. 1.0 GHz G4) for scalar code there's not much difference:

    From that you can calculate that of the six scalar dnetc cores the 1.0 GHz G4 wins at three (10%, 7%, 3% faster), the 1.15 GHz PPC460EX wins at one (17% faster) and with two dnetc cores there's less than 1% difference between the CPUs. For AltiVec code on the G4 vs. scalar code on the PPC460EX the outcome would be obvious, though.
    But also for cache and RAM performances the Peg2 G4 is not the clear winner over the Sam460ex:

    As you see, while the Peg2 G4 wins in L2 throughput it apparently loses in L1 and RAM throughputs against the Sam460ex.
    And finally in the Sam460ex there's SATA2 vs. Peg2's PATA, USB2 vs. Peg2's USB1 and PCIe vs. Peg2's (fake) AGP.

    Yes, I know that OS4 on Peg2 relies on RTAS. Btw, Trevor Dickinson revealed that he was beta tester for OS4 on Peg1:

    It's a pity the port to Peg1 never came off. It would have made my Peg1 sale much more profitable than it was ;-)

    > I doubt Genesi/DCE will ever update it

    DCE? You mean bplan here, right? And yes, this ship has definitely sailed by now. When I still had my Peg1 I really wanted to have better Linux compatibility, so it had really pissed me off that BBRV were promising a firmware update for years but nothing ever came.
