Intel launches all-new PC architecture with Core i5/i7 CPUs

Intel brought its mainstream desktop CPU lineup into the Nehalem era today with the launch of the Core i7 860 and 870, and the Core i5 750. Also launched today is the P55 chipset, which implements a new system architecture that represents a significant break with Intel's past. In this short article, we'll take a brief look at each, in turn.
In previous articles we've covered Nehalem's microarchitectural improvements to the Core 2 Duo lineage, so we won't recap that here. What is worth repeating, though, is that Nehalem is Intel's first x86 design to feature an on-die memory controller. This significantly changes the system topology, but in a direction that AMD already went way back in 2003.
