Introduction
The Intel Xeon Processor with 533 MHz Front Side Bus is based on the Intel NetBurst
micro-architecture, which operates at significantly higher clock speeds and delivers performance
levels that are significantly higher than previous generations of IA-32 processors. While based on
the Intel NetBurst micro-architecture, it maintains the tradition of compatibility with IA-32
software.
The Intel NetBurst micro-architecture features begin with innovative techniques that enhance
processor execution such as Hyper Pipelined Technology, a Rapid Execution Engine, Advanced
Dynamic Execution, enhanced Floating Point and Multimedia unit, and Streaming SIMD
Extensions 2 (SSE2). The Hyper Pipelined Technology doubles the pipeline depth in the processor,
allowing the processor to reach much higher core frequencies. The Rapid Execution Engine allows
the two integer ALUs in the processor to run at twice the core frequency, which allows many
integer instructions to execute in one half of the internal core clock period. The Advanced Dynamic
Execution improves speculative execution and branch prediction internal to the processor. The
floating point and multi-media units have been improved by making the registers 128 bits wide and
adding a separate register for data movement. Finally, SSE2 adds 144 new instructions for double-
precision floating point, SIMD integer, and memory management for improvements in video/
multimedia processing, secure transactions, and visual internet applications.
Also part of the Intel NetBurst micro-architecture, the front side bus and caches on the Intel Xeon
processor with 533 MHz Front Side Bus provide tremendous throughput for server and workstation
workloads. The 533 MHz Front Side Bus provides a high-bandwidth pipeline to the system
memory and I/O. It is a quad-pumped bus running off a 133 MHz Front Side Bus clock making
4.3 Gigabytes per second (4,300 Megabytes per second) data transfer rates possible. The Execution
Trace Cache is a level 1 cache that stores approximately twelve thousand decoded micro-
operations, which removes the decoder latency from the main execution path and increases
performance. The Advanced Transfer Cache is a 512 KB on-die level 2 cache running at the speed
of the processor core providing increased bandwidth over previous micro-architectures. The Intel
Xeon Processor with 533 MHz Front Side Bus also has 1-MB and 2-MB on-die, full speed level
3 cache1 with 8-way associativity and Error Correcting Code (ECC) .
In addition to the Intel NetBurst micro-architecture, the Intel Xeon processor with 533 MHz Front
Side Bus includes a groundbreaking new technology called Hyper-Threading technology, which
enables multi-threaded software to execute tasks in parallel within the processor resulting in a more
efficient, simultaneous use of processor resources. Server applications can realize increased
performance from Hyper-Threading technology today, while workstation applications are expected
to benefit from Hyper-Threading technology in the future through software and processor
evolution. The combination of Intel NetBurst micro-architecture and Hyper-Threading technology
delivers outstanding performance, throughput, and headroom for peak software workloads
resulting in faster response times and improved scalability.
The Intel Xeon processor with 533 MHz Front Side Bus is intended for high performance worksta-
tion and server systems with up to two processors on a single bus. The processor supports both uni-
and dual-processor designs. The Intel Xeon with 533 MHz Front Side Bus processors do not incor-
porate system managment devices (PIROM, OEM Scratchpad EEPROM, and thermal sensor), but
offer direct access to the pins of an on-die thermal diode. These output pins can interface with a
thermal sensor device that is placed on the baseboard. The Intel Xeon processor with 533 MHz
Front Side Bus is packaged in a 604-pin flip chip micro-PGA2 (FC-mPGA2) package, and utilizes
a surface mount ZIF socket with 604 pins.
The FC-mPGA2 package contains an extra pin (located at location AE30) compared to the INT-
