Dear CPU Scorekeeper

I noticed there were no scores for the Xeon series of processors (specifically the Pentium II Xeon 450, the Pentium III Xeon 450, the Pentium III Xeon 500 and the Pentium III Xeon 550). I am a novice when it comes to this field, so perhaps there is some reason for their omission (too new and too little benchmark material?) I am just guessing here.

In your professional opinion, how would you score these processors (roughly if need be)?

Though we previously focussed our information on the mainstream home and business PC workstation class of CPU's, Intel's Xeon line of CPU's has now been included in the CPU Scorecard list. The Xeon line is marketed primarily toward higher end servers and multiprocessor environments in competition with DEC's Alpha and Sun's UltraSparc processors.

Unfortunately, there is little benchmarking information available comparing Xeon's with the mainstream lines of CPU's. This is not helped by the fact that Xeon's are available in several different on-board cache configurations, making general comparisons dubious at best.

Roughly speaking, however, the Pentium-II Xeon's will score somewhere between a Pentium-II and a Pentium-III at the same rated clockspeed. The Xeon-III's will score slightly faster than their Pentium-III cousins. Intel, however, charges a premium for their Xeon's, as they are held to a much higher reliability standard of performance demanded by mission-critical server applications.

AMD's K7 CPU, due out in June, is touted to be able to compete against Intel's Xeon line in server applications. When it is finally released, you will most likely see both K7's and Xeons on the CPU Scorecard as these sumo's square off.
