You can go to the standards sites (www.spec.org, www.tpc.org) to get some idea of the processing power of these machines. You might also want to look at the index of the world's best performing machines at www.top500.org.
However, comparison is still difficult. You will find that the top end machines will outperform mainframes in a number of areas. But this is assuming a single task environment, if you have the requirement for complex work mixes then the answer may not be so simple. > -----Original Message----- > From: Gerard Graham [mailto:[EMAIL PROTECTED] > Sent: 27 March 2003 15:23 > To: [EMAIL PROTECTED] > Subject: Processor Comparisons > > > Has anyone gotten anywhere with processor comparisons ?
