Features and Benefits of the Intel® Pentium® 4 Processor 600 Sequence
Features 
Benefits
Hyper-Threading (HT)  
HT Technology takes advantage of threaded applications by allowing the processor core to function as 
Technology
two logical processors. This provides increased system responsiveness in multi-tasking environments by 
 
dividing workloads into processes and software threads that can be independently scheduled and dispatched.
2MB Level 2 Cache 
The processor core is equipped with its own 2MB L2 cache that gives the core fast access to the data 
 
used most often.
800 MHz Front Side Bus 
Delivers excellent system bandwidth for efficient and improved system performance.
Execute Disable Bit
2
 
When enabled with a supported operating system, the Execute Disable Bit allows memory to be marked  
 
as executable or non-executable. If code attempts to run in non-executable memory, such as when  
 
malware exploits buffer overrun vulnerabilities, the processor raises an error to the operating system.
Intel® Extended Memory 64  
Intel EM64T enhances Intel 32-bit architecture, giving the desktop processor platform access to larger 
Technology (Intel® EM64T)
amounts of memory. With appropriate 64-bit supporting hardware and software, platforms based on  
 
an Intel processor supporting Intel EM64T can enable use of extended virtual and physical memory.
Streaming SIMD Extensions 
Single Instruction Multiple Data (SIMD) technology accelerates performance on a wide variety of applications 
 
including multimedia, video and audio encoding/decoding, 3-D graphics and image processing.
Enhanced Intel SpeedStep®  
EIST allows the system to dynamically adjust processor voltage and core frequency, which can decrease 
Technology (EIST)
3
 
average power consumption and average heat production. Combined with existing power saving features, 
 
EIST provides an excellent balance between providing power when you need it and conserving it when  
 
you don’t.
Enhanced Halt State
3
 
Enhanced Halt State is activated when the Halt instruction is executed by the processor. The operating 
 
system goes into idle mode which lowers frequency and voltage (Dynamic Voltage Identification, or 
 
Dynamic VID) to help reduce power consumption.
Intel® Thermal Monitor 2
3
 
This enhanced version of Intel Thermal Monitor lowers frequency and voltage (Dynamic VID) to help  
 
reduce power consumption.
Intel Designed Thermal  
Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated from  
Solution for Boxed  
running the fan at higher speeds for thermal performance. The fan speed control technology is based on  
Processors
actual CPU temperature and power usage.
  Intel processor numbers are not a measure of performance. Processor 
numbers differentiate features within each processor family, not across 
different processor families. See www.intel.com/products/processor_ 
number/ for details.

 Intel® Hyper-Threading Technology and Intel® Extended Memory 64 
Technology (Intel® EM64T) require a computer system with a processor, 
chipset, BIOS, enabling software and/or operating system, device  
drivers and applications designed for these features. Performance will 
vary depending on your configuration. Contact your vendor for more  
information. See www.intel.com/products/ht/hyperthreading_more.htm/ 
and www.intel.com/technology/64bitextensions/ for more information.

 Enabling Execute Disable Bit functionality requires a PC with a processor 
with Execute Disable Bit capability and a supporting operating system. 
Check with your PC manufacturer on whether your system delivers 
Execute Disable Bit functionality.

 Enhanced Intel SpeedStep® Technology (EIST), Enhanced Halt State and 
Intel® Thermal Monitor 2 for specified units of this processor available 
Q2/06. See the Processor Spec Finder at processorfinder.intel.com or 
contact your Intel representative for more information.

 The acoustic benefits of the 4-pin header are reliant on a properly de-
signed motherboard. Consult your board manufacturer for compatibility.
