Here is an excerpt from a chart that was sent to me: Perf. relative to: A400-100-110 A500-100-140 A500-200-140 <snip> Series 918 1.7 2.5 4.2 Series 928 1.2 1.8 3.0 <snip> Then I look on another chart and I see this: Relative performance to HP perf. unit: 918 928 1.3 1.8 So how do I measure the added performance from say a 918 to A400-100-110? Is the A400 "1.7 HP Perf. Units" better than the 918? Does that mean it is more than twice as powerful? So then I would calculate about a 130% increase in processing power.... is this correct? With these new processors it's difficult to understand what they are trying to tell me (us).
