Some specification of this processor :

  • Quad-core
  • 731 million transistors (incredible !!!)
  • 45nm process technology.
  • ovviamente 64bit
  • 2.66 GHz to 3.2 GHz
  • Core Name: Bloomfield
  • Socket B (LGA 1366)
  • 8MB 3rd Level Cache
  • Hyper-threading technology, or also known as Simultaneous Multi-Threading
  • New SSE4.2 Instructions <-- this are for math calc
  • Integrated DDR3 Memory Controller
  • Power Gate Transistors
  • In particular, this processor have a switch ,for each core, to power on/off (Power Gate Transistors) the unused core.

    Concept of Power Gate Transistors :
