Peter Glaskowsky says in a newsletter sent to Microprocessor Forum customers that there were 64-bit chips in several RISC based Windows NT desktops in the mid 1990s.
He adds that some of the claims are overstated and that the benchmarks Apple published for the Pentium 4 and the Xeon are "considerably higher than those that Apple reported".
Glaskowsky also accuses Apple of irrelevance. He says: "Apple knows perfectly well that clock frequency per se is essentially meaningless".
However, given this blast at Apple's hype, he does say that Powermacs are, once more, competitive with Windows PCs in performance. They also have advantages that will help Apple expand its market, he says.
He says that there are now five CPU vendors with seven artchitectures. PA-RISC and MIPS server chips are "on life support", AMD is investing in Opteron, and Sun will breathe life into the SPARC architecture with its Throughput Computing multithreading and chip multiprocessing scheme.
The "seven horses", he says, will make a good exciting horse race. µ
