Processor/Memory Subsystem

3.2Intel 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
