Introduction
The Quad-Core Intel® Xeon® Processor 5300 Series are 64-bit server/workstation
processors utilizing four Intel Core™ microarchitecture cores. These processors are
based on Intel’s 65 nanometer process technology combining high performance with
the power efficiencies of low-power Intel Core™ microarchitecture cores. The Quad-
Core Intel® Xeon® Processor 5300 Series consists of two die, each containing two
processor cores. All processors maintain the tradition of compatibility with IA-32
software. Some key features include on-die, 32 KB Level 1 instruction data caches per
core and 4 MB shared Level 2 cache per die (8 MB Total Cache per processor) with
Advanced Transfer Cache Architecture. The processor’s Data Prefetch Logic
speculatively fetches data to the L2 cache before an L1 cache requests occurs, resulting
in reduced bus cycle penalties and improved performance. The 1333 MHz Front Side
Bus (FSB) is a quad-pumped bus running off a 333 MHz system clock, which results in
10.6 GBytes per second data transfer. The 1066 MHz Front Side Bus is based on a 266
MHz system clock for an 8.5 GBytes per second data transfer rate. The Quad-Core
Intel® Xeon® Processor X5300 Series offers higher clock frequencies than the
Quad-Core Intel® Xeon® Processor E5300 Series for platforms that are targeted for
the performance optimized segment. The Quad-Core Intel® Xeon® Processor L5300
Series is a lower voltage, lower power processor intended for ultra dense platforms.

Enhanced thermal and power management capabilities are implemented including
Thermal Monitor 1 (TM1), Thermal Monitor 2 (TM2) and Enhanced Intel SpeedStep®
Technology. TM1 and TM2 provide efficient and effective cooling in high temperature
situations. Enhanced Intel SpeedStep® Technology provides power management
capabilities to servers and workstations.

The Quad-Core Intel® Xeon® Processor 5300 Series features include Advanced
Dynamic Execution, enhanced floating point and multi-media units, Streaming SIMD
Extensions 2 (SSE2) and Streaming SIMD Extensions 3 (SSE3). Advanced Dynamic
Execution improves speculative execution and branch prediction internal to the
processor. The floating point and multi-media units include 128-bit wide registers and a
separate register for data movement. SSE3 instructions provide highly efficient double-
precision floating point, SIMD integer, and memory management operations.

The Quad-Core Intel® Xeon® Processor 5300 Series supports Intel® 64 architecture
as an enhancement to Intel's IA-32 architecture. This enhancement allows the
processor to execute operating systems and applications written to take advantage of
the 64-bit extension technology. Further details on Intel 64 architecture and its
programming model can be found in the Intel® 64 and IA-32 Architecture Software
Developer's Manual.

In addition, the Quad-Core Intel® Xeon® Processor 5300 Series supports the Execute
Disable Bit functionality. When used in conjunction with a supporting operating system,
Execute Disable allows memory to be marked as executable or non executable. This
feature can prevent some classes of viruses that exploit buffer overrun vulnerabilities
and can thus help improve the overall security of the system. Further details on
