Dual-Core Processing
Intel dual-core processors have two complete processor cores in one physical package running at the same frequency. The cores share the same interface with chipset and memory,
but each core has its own set of registers and cache for truly parallel computing.
Intel® Virtualization
With Intel VT, one hardware platform functions as multiple “virtual” platforms. For businesses, Intel VT offers improved manageability, limiting downtime and maintaining worker
Technology (Intel® VT)

productivity by isolating computing activities into separate partitions. In the home, Intel VT allows creating unique user environments for multiple family members using the same
platform simultaneously.
2 x 2MB Level 2 Cache
Each processor core has its own 2MB L2 cache (4MB total) enabling improved overall system performance by allowing each core to have faster access to larger amounts of the
most often used data.
800 MHz Front Side Bus
Delivers excellent system bandwidth for efficient and improved system performance.
Execute Disable Bit
3
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 provides an enhancement to Intel’s 32-bit architecture by allowing the desktop processor platform to access larger amounts of memory. With appropriate 64-bit
Technology (Intel® EM64T)

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 average power consumption and average heat production. Combined
Technology (EIST)
4
with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving it when you don’t.
Intel Designed Thermal
Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated from running the fan at higher speeds for thermal performance. The fan speed
Solution for Boxed
control technology is based on actual CPU temperature and power usage.
Processors

Intel® Virtualization 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.

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.
3
Enabling Execute Disable Bit functionality requires a PC with a proces-
sor 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) 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.

How is Dual-Core Processing Different
from Hyper-Threading Technology?
from Hyper-Threading Technology?
The Intel dual-core processor is an evolution of Hyper-Threading
(HT) Technology. Both enable a multi-threaded experience for
applications written to take advantage of multiple threads,
but dual-core processing brings more resources and comput-
ing throughput to the PC. Dual-core processing allows for true
parallel computing capabilities on the desktop PC platform.
