2 Duo that carries the
following features:
Processor
The G33 Northbridge (NB) and ICH9 Base Southbridge (SB) chipsets are based on an
innovative and scalable architecture with proven reliability and performance.
G33 (NB)
• Supports 36-bit host bus addressing, allowing the CPU to
access the entire 64 GB of the memory address space.
• 2 GB/s point-to-point Direct Media Interface (DMI) to ICH9 (1
GB/s) each direction
• One, 16-lane PCI Express x16 for Graphics Attach, compli-
ant to the PCI Express Base Specification revision 1.1
• Supports 512 Mb and 1Gb DDR2 or DDR3 technologies for
x8 and x16 devices
“Hyper-Threading” technology enables the operating system into thinking it’s hooked
up to two processors, allowing two threads to be run in parallel, both on separate
“logical” processors within the same physical processor.
Chipset
