A senior analyst for the Microprocessor Report has described Apple’s claims that the Power Mac G5 is the world’s fastest PC and the first 64-bit system as “simply not true.” According to The Inquirer, Peter Glaskowsky said 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, and that actual Pentium 4 and Xeon benchmarks are “considerably higher than those that Apple reported.” However, he does say that Power Macs are once again competitive with Windows PCs in performance.
