Bottom line: isn't your >beloved Cray out-performed by nowadays micro processors available from your >local super market? I do not see how it is outperformed. Do you suggest that 1127.00 for cray is outperformed by 77.40 for the Athlon or maybe you compare only Gflops per processor and in this case 1127/1900 is smaller than 77.40/78 for the athlon. I also do not understand the meaning of these numbers What is the meaning of 78 processors? Does the commercial athlon has 78 processors and if it does then what is the reason that Deep Fritz is going to use only 8 processors against kramnik? Uri
