New Desktop Processor Intel Core i7

Posted by sudhirmangla November 19, 2008

Intel plans to launch its newest generation of desktop processors on Monday. Called Core i7, the chips are aimed at the high-end desktop and gaming market.

The move puts Intel ahead of its rival AMD by more than a few months, as AMD’s comparable desktop processor isn’t scheduled to launch until early next year.

The Core i7 will be almost four to six times faster than Intel’s current platform, says the company, and will have greater power efficiency than ever. It is based on the 45-nanometer production technology that first appeared in a server chip called Xeon (aka Penryn), which debuted earlier this year.

The 45-nm chips utilize smaller circuitry than the previous, 65-nm generation, making them faster, and also enabling Intel to manufacture them more cheaply.

The new Core i7 chips are based on a newly designed microarchitecture called Nehalem, which includes major design changes in areas such as power management and integrated memory control.

The first three quad-core Core i7 chips from Intel will reintroduce "hyperthreading" technology, which gives the chips the ability to execute 8 threads simultaneously on 4 processing cores, greatly increasing their processing power. Hyperthreading was seen earlier in Pentium 4 chips and some Xeon processors from Intel.

Core i7 processors have:

  • Quad-core
  • 731 million transistors
  • 8MB 3rd Level Cache
  • Hyper-threading technology, or also known as Simultaneous Multi-Threading
  • New SSE4.2 Instructions
  • Integrated DDR3 Memory Controller
