Things are pretty bad when AMD boosters are left debating base vs peak to decide whether one Nehalem should be said to have slightly outperformed two Shanghai or slightly underperformed two Shanghai.
The basic fact is chip for chip Nehalem utterly downright owns Shanghai to a degree I can't ever remember before in this industry. Things were bad with C2D vs Barcelona but they are going to be far, far worse for AMD in the i7 vs Shanghai era. Given the global economic outlook this is probably end-game for AMD. Buh-bye now Pete.
