Introduction
ALL INFORMATION IN THIS DOCUMENT IS SUBJECT TO CHANGE.
The Intel
®
 Xeon
®
 Processor 7200 Series and 7300 Series are multi-processor servers 
utilizing four Intel
® 
Core
TM
 microarchitecture cores. These processors are based on 
Intel’s 65 nanometer process technology combining high performance with the power 
efficiencies of a low-power microarchitecture. The Quad-Core Intel
®
 Xeon
®
 7300 
Series consists of two die, each die containing two processor cores. The Dual-Core 
Intel
®
 Xeon
®
 7200 Series consists of two die, each die containing one processor core. 
All processors maintain the tradition of compatibility with IA-32 software. Some key 
features include on-die, 64 KB Level 1 instruction data caches per die and 2x4MB 
shared Level 2 cache 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 1066 
MHz Front Side Bus (FSB) is a quad-pumped bus running off a 266 MHz system clock 
making 8.5 GBytes per second data transfer rates possible. The Quad-Core Intel
®
 
Xeon
®
 X7350 processor offers higher clock frequencies than the other Quad-Core 
Intel
®
 Xeon
®
 Processor 7300 Series for platforms that are targeted for the 
performance optimized segment. The Quad-Core Intel
®
 Xeon® L7345 Processor is a 
lower voltage, lower power processor.
Enhanced thermal and power management capabilities are implemented including 
Thermal Monitor (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 allows trade-offs to be made 
between performance and power consumption. This may lower average power 
consumption (in conjunction with OS support).
The Intel
®
 Xeon
®
 Processor 7200 Series and 7300 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 Intel
®
 Xeon
®
 Processor 7200 Series and 7300 Series support Intel
®
 64 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 Technology and its programming 
model can be found in the Intel
®
 64 and IA-32 Architectures Software Developer's 
Manual.
In addition, the Intel
®
 Xeon
®
 Processor 7200 Series and 7300 Series support 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 Execute Disable can be found at
