    Thanks for the pointer. I overlooked this important piece of information in the press release. A value of 1.52 DMIPS/MHz clearly points to a PPC405 core (compare: PPC405EX, PPC405EXr). So I think we have it. Thanks again :-)

    Yes, PPC460 (as well as PPC440) delivers 2.0 DMIPS/MHz. But e300 delivers slightly less, namely 1.9 DMIPS/MHz.
