Introduction
The Intel
i7-900 desktop processor series are intended for high performance high-end desktop,
Uni-processor (UP) server, and workstation systems. Several architectural and
microarchitectural enhancements have been added to this processor including four
processor cores in the processor package and increased shared cache.
The Intel
i7-900 desktop processor series are the first desktop multi-core processor to
implement key new technologies:
• Integrated memory controller
• Point-to-point link interface based on Intel QPI

The Intel Core™ i7-900 desktop processor series refers to the Intel Core™ i7-900
desktop processors i7-960, i7-950, i7-940, i7-930, and i7-920.
Note:
The Intel Core™ i7-900 desktop processor Extreme Edition series refers to the Intel
Core™ i7-900 desktop processor Extreme Edition i7-975 and i7-965.
The processor is optimized for performance with the power efficiencies of a low-power
microarchitecture.
