More on New Intel Architecture

Charlie over at The Inquirer has a bit more information and analysis on the new Intel architecture for you to look over.
The basic structure is a four issue wide core, without going into specifics, they said the Merom cores can keep up a sustained 4 ops from issue to retire. This probably has a bunch of caveats, addenda and asterisks, but it is clear that wider is the course for the day. Each pipe is a full pipe versus the old P6 derived simple and complex pipe structures. The number of ALU ports are greatly increased also.
The family picks up a lot from the previous Yonah architecture, the dual core, shared L2 and low power architectures. It also picks up some of the baggage like the long in tooth FSB and stronger integer performance than floating point. Everything is new, even if it looks similar.
