I am sure everyone here has read this, but if not packs some cool info.
http://en.wikipedia.org/wiki/Intel_Core_3
Nehalem represents the largest architectural change in the Intel x86 family since the Pentium Pro in 1995. The Nehalem architecture has many new features. The ones that represent significant changes from the Core 2 include:
* The FSB is replaced by a QuickPath interface. This means that motherboards must use a chipset that supports QuickPath. As of October 2008[update], only the Intel X58 does this.
* The memory controller is on the processor, not in a separate chip, so the memory is directly connected to the processor.
* The memory controller supports three channels of memory, and each channel can support one or two DDR3 DIMMs. This means that motherboards for the Core i7 have three or six DIMM slots instead of two or four, and that DIMMs should be installed in sets of three, not two.
* The Core i7 only supports DDR3.
* Core i7 is a single-die device: all four cores, the memory controller, and all cache are on a single die.
* Core i7 cores re-implement Hyper-threading. Each of the four cores can process two threads simultaneously, so the processor appears to the OS as eight CPUs. This feature was present in the older Netburst architecure but was dropped in Core.
* Core i7 has an on-die shared 8MB L3 cache.
* Core i7 is not intended for multi-processor motherboards, so it has only one QuickPath interface.
* Core i7 uses 45nm process technology.
* Core i7 has 731M transistors.
