Intel Core 2 Quad Q9450 & Q9550 "Yorkfield" Review

“After the many pages of benchmarks, we guess the writing on the wall is pretty clear that Intel's Penryn-based processors have more than proved their worth. After all clock-for-clock, the Penryn processors we tested to-date (the QX9650, Q9550 and Q9450) easily best the older outgoing Kentsfield processors (QX6850, Q6700 and Q6600) by a margin of a few percentage points to more than 10% depending on the test scenario. And while their price points are similar to old Kentsfield models, the new processors actually deliver more for less from a clockspeed perspective. Throw in industry leading performance-per watt factor into the mix and you have a winner.”
