According to Cheryl Watson's CPU Charts the 2098-O02 is 359 MIPS as opposed to 319 MIPS for the 2066-002. That's about a 12% improvement. I'm not sure what you mean by "10 points" but I would expect a CPU utilization drop in the range of 10 to 12%.
Someone mentioned the "technology" MSU dividend. I believe that has to do with the software MSUs where the software MSUs for the machine as compared to the actually processor power improved in order to keep software costs down. This would be reflected in your software license charges going down if you are on sub-capacity pricing. It wouldn't have anything to do with the actually CPU utilization. The SW MSU rating of the 2066-002 is 54 (MIPS to MSU ratio of 5.9) while the 2098 O02 rating is 44 (ratio of 8.2). If you are on sub-capacity pricing for your software you'll should be seeing a drop in your monthly software invoice from IBM for the same CPU utilization in MIPS.

Our CPU utilization dropped by about 10 points on a 24 hour window as did our CPU overhead statistics. We were and are z/OS V1R9 plus toleration maintenance for a z10. We changed nothing in all of our function, WLM, IEAOPT, or reporting processes, SMF,RMF,SAS,MXG and are concerned that we may be producing numbers that will not stand scrutiny. Is there a place in any of this where we might specify a 'normalization' to a z800 processor type or some such? Your kind and gentle thoughts, please.
