Is Nehalem just a souped up Penryn?
Nehalem is essentially a completely new family of Intel processors which have brought back Hyper Threading, feature an integrated memory controller (yes, AMD did that first) supporting DDR3 RAM, and have done away with the Front Side Bus (FSB) through Quick Path architecture (in an implementation not too different from AMD’s Hyper Transport) which allows for 25.6 GB/sec link: double the bandwidth as the X48 chipset’s 1.6 GHz FSB. Nehalem also can dynamically manage darn near everything: power, threads, cache, cores and bus.
