3.2 Intel Processor
These systems support an Intel Pentium Dual-Core G6950, Core i3, Core i5, or Core i7 processor
in an LGA1156 package mounted with a heat sink in a zero-insertion force socket. The mounting
socket allows the processor to be easily changed for upgrading.
3.2.1 Intel Processor Features
Primary features of the processors supported by these systems include:
■
Execution Trace Cache— A new feature supporting the branch prediction mechanism, the
trace cache stores translated sequences of branching micro-operations (ops) and is checked
when suspected re-occurring branches are detected in the main processing loop. This feature
allows instruction decoding to be removed from the main processing loop.
■
Rapid Execution Engine—Arithmetic Logic Units (ALUs) run at twice (2x) processing
frequency for higher throughput and reduced latency.
■
Up to 8 MB of L3 cache—Using a 32-byte-wide interface at processing speed, the large L3
cache provides a substantial increase in processing power over earlier processor versions.
■
Advanced dynamic execution—Using a larger (4K) branch target buffer and improved
prediction algorithm, branch mis-predictions are significantly reduced
■
Additional Streaming SIMD extensions (SSE2, SSE3, SSE4.1, and SSE4.2)—In addition to
the SSE support provided by earlier processors, the latest processors include additional
MMX instructions that enhance the following operations:
❏
Streaming video/audio processing
❏
Photo/video editing
❏
Speech recognition
❏
3D processing
❏
Encryption processing
■
Integrated dual-channel DDR3 memory controller
■
Direct Media Interface (DMI) bus speeds up to 2.5 GT/s.
■
Flexible Display Inteface (FDI) supporting integrated and/or separate graphcis controllers
