Intel® Xeon® Processor 3100 Series Datasheet
The Dual-Core Intel® Xeon® Processor 3100 Series, like the previous Dual-Core Intel® Xeon® Processor 3000 Series, are based on the Intel® Core™ microarchitecture. The Intel Core microarchitecture combines the performance of previous generation products with the power efficiencies of a low-power microarchitecture to enable smaller, quieter systems. The Dual-Core Intel® Xeon® Processor 3100 Series is a 64-bit processor that maintains compatibility with IA-32 software.
In this document, the Dual-Core Intel Xeon Processor 3100 Series may be referred to simply as “the processor.” The processors utilize Flip-Chip Land Grid Array (FC-LGA8) package technology, and plugs into a 775-land surface mount, Land Grid Array (LGA) socket, referred to as the LGA775 socket.
The processor is a dual-core processor, based on 45-nm process technology. The processor features the Intel® Advanced Smart Cache, a shared multi-core optimized cache that significantly reduces latency to frequently used data. The processor features a 1333 MHz front side bus (FSB) and 6 MB of L2 cache. The processor supports all the existing Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3), Supplemental Streaming SIMD Extension 3 (SSSE3), and the Streaming SIMD Extensions 4.1 (SSE4.1). The processor supports several Advanced Technologies: Execute Disable Bit, Intel® 64 architecture, Enhanced Intel SpeedStep® Technology, Intel® Virtualization Technology (Intel® VT), and Intel® Trusted Execution Technology (Intel® TXT).
The processor's front side bus (FSB) utilizes a split-transaction, deferred reply protocol. The FSB uses Source-Synchronous Transfer of address and data to improve performance by transferring data four times per bus clock (4X data transfer rate). Along with the 4X data bus, the address bus can deliver addresses two times per bus clock and is referred to as a "double-clocked" or 2X address bus. Working together, the 4X data bus and 2X address bus provide a data bus bandwidth of up to 10.7 GB/s.
