Procesori iz Penryn obitelji

• Penryn family of processors will be launched in the second half of this year. Details of Nehalem, which will see the light in the second half of 2008, were also provided. Both new processors are based upon the current Intel Core micro architecture and use Intel's newest 45nm Hi-k process technology with its hafnium-based Hi-k + metal gate transistor design. Penryn will deliver higher IPC and higher clock speeds. Intel wouldn't say more than "more than 3 GHz", but considering that the FSB is bumped up to 1600 MHz, 3.2 GHz is likely. Penryn family processors are supposed to be socket-compatible, meaning that on the desktop we will see them introduced as LGA-775 CPUs.

Nehalem arhitektura

• Nehalem can contain up to eight cores per die. Combined with 2-way Simultaneous Multi-Threading (SMT or Hyper-Threading), you'll have the ability to execute up to 16 threads on one chip. Nehalem will also use multi-level shared cache, meaning that Nehalem could very well have a similar cache hierarchy to AMD's Barcelona. Nehalem will no longer use a FSB but a serial point to point interconnect and will have an integrated memory controller (IMC).
