Meynaf twierdzi, ze PPC jest niewydajny bo taki sam kod jest okolo 2x razy wiekszy niz dla innych procesorow, przez to wymaga 2x wiekszego cache.

On Monday (April 21), P.A. Semi informed its customers it was being acquired and it could no longer guarantee supplies of its chips. The startup did not identify the acquiring company but said that company may be willing to supply the chip on an end-of-life basis, if it could successfully transfer a third-party license to the technology.
That license in question is probably a PowerPC architectural license that P.A. Semi has with IBM Corp. that allowed the startup to design its own PowerPC chip from scratch. IBM was not immediately available for comment on the issue.
