as a native English speaker I took the "1% for 1%" at face value, its exact meaning. that's not cynicism, you may need a new English dictionary. Intel's performance per watt credentials are only recently improved, painful memories of Prescott and to a lesser extent Northwood still remain. it wouldn't be the first time Intel has "bought" increased performance at the "cost" of extra power consumption.
Being a native English speaker doesn't justify you extrapolating things that aren't there. If your power efficiency predictions are right ("1% for 1%"), Intel is right. If Intel is right, you are not necessarily right however. The prediction of yours was indeed cynical ("they may not lie, but they certainly won't do any better than their worst guarantee", sort of). Now what's the need of discussing this.
In mathematical terms, Intel says: [Nehalem's Performance Per Watt]/[Penryn's "PPW"]>=1
You say: [Nehalem's PPW]/[/Penryn's PPW]=1
It doesn't take a rocket scientist to notice the difference.
Besides, as a native English speaker you should try to spell properly. As of now the way you write is actually deeply miscrediting your whole native English speaker argument. So don't go around flaunting your first language like that if you're going to be sloppy, it doesn't help you.
smilingcrow > Darn. That's bad news. If single-threaded performance isn't improving, there probably will be little reason to upgrade. Hopefully proper triple-channel memory as well as an optimized motherboard/chipset, BIOS and drivers may help. Let's hope!

skeptical, perhaps is a term with fewer negative connotations. Intel's interest in power efficiency is only a relatively recent phenomenon, painful memories of Prescott and to a lesser extent Northwood still remain. it wouldn't be the first time Intel has "bought" increased performance at the "cost" of extra power consumption.
Err... it appears you edited your post slightly before I posted mine. Now it's a much less hostile version, that's good.
Anyway, I agree skeptic would work as well.
