Intel Core i7

Posted: August 7, 2009 in Discover Technology


Intel Core i7 is a family of several Intel desktop x86-64 processors, the first processors released using the Intel Nehalem microarchitecture and the successor to the Intel Core 2 family.The Core i7 identifier applies to the initial family of processors[5][6] codenamed Bloomfield.Core i7, first assembled in Costa Rica,[10] was officially launched on November 17, 2008[11] and is manufactured in Arizona, New Mexico and Oregon, though the Oregon plant is moving to the next generation 32 nm process.



The Core i7 has many new features that represent significant changes from the Core 2:

1.The new LGA 1366 socket is incompatible with earlier processors.
2.On-die memory controller: the memory is directly connected to the processor. It is called the uncore part and runs at a different clock (uncore clock) of execution cores.
3.Three channel memory: each channel can support one or two DDR3 DIMMs. Motherboards for Core i7 generally have three, four (3+1), or six DIMM slots.
Support for DDR3 only.


4.The front side bus has been replaced by the Intel QuickPath Interconnect interface.

5.The following caches:
32 KB L1 instruction and 32 KB L1 data cache per core
256 KB L2 cache (combined instruction and data) per core
8 MB L3 (combined instruction and data) “inclusive”, shared by       all cores.

6.Only one QuickPath interface: not intended for multi-processor      motherboards.
45nm process technology.
731M transistors.
263 mm2 die size.
7.Sophisticated power management can place an unused core in a      zero-power mode.
8.  Support for SSE4.2 & SSE4.1 instruction sets.
