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
