Re: In my book your portrayal of the miss is about off a dimension, mate: It's not a 20% miss, but a 200% miss.

I don't know what planet your book is based, but over here when someone aims for 5.0 and delivers less than 4.0, that's 4/5 = 0.8, or at least a 20% miss.

Re: In essence: Prescott offers no performance increase at all, but has a power penalty over its predecessor nevertheless.

Yet you incorrectly attributed this to a process problem, rather than a micro-architecture problem. Do you have any other reasons to object to my previous statement about process shrinks offering improved performance and power, other than the Northwood to Prescott transition?
