What does hardware provide for this that can't be done >in software? This question has not been answered. It is a good question. I am still looking for the reason the cpw per processor of the new regatta 890 is only 40% more than that of the former high end 840. Even though the clock speed is 100% greater. My calculations below. Steve Richter ( from the iSeries handbook, v5r1 ) model 840, #2354. Cpw 15150 to 20200. Processors 18 to 24. Processor speed: 600 Mhz. 15150 / 18 = 841 CPW per processor. 20200 / 24 = 841 CPW per processor. Model 890. 37,400 CPW. 32 Processors. Speed: 1.2 Ghz ( as per press reports ) 37,400 / 32 = 1168.75 CPW per processor. 1168 CPW = 140% of 841 CPW.
