Intel® Celeron® Processor

Intel® Celeron® Processor

Energy-efficient computing for the desktop PC

Overview

Take basic computing to new levels with the Intel® Celeron® processor dual-core. Because many software applications for everyday tasks are now designed for dual-core processors, users can be more creative and productive in the home, office, or classroom.

In addition, security and virus protection often means running more than one application at a time, and the Intel Celeron processor dual-core has the power to run them simultaneously.

Based on energy-efficient microarchitecture, the Intel Celeron processor dual-core delivers superior energy-efficient dual-core performance.

Energy Efficiency

Intel® Intelligent Power Capability, a feature of the Intel Celeron processor dual-core, optimizes energy usage in the processor cores by turning computing functions on only when needed.

This improves performance as well as the processor’s energy efficiency by operating at lower frequencies that require less power to run. These more energy-efficient processors support smaller and quieter desktop PCs.

Better Acoustics

The Intel Celeron processor dual-core is equipped with a Digital

Thermal Sensor (DTS) that enables efficient processor and platform thermal control. Thermal sensors located within the processor measure the maximum temperature on the die at any given time. The acoustic benefit of temperature monitoring is that system fans spin only as fast as needed to cool the system, and slower spinning fans generate less noise.

Platform Support

Combining the Intel Celeron processor dual-core with an

Intel® Express chipset-based board delivers added benefits.

Integrated Intel® High Definition Audio and Intel® Graphics

Media Acceleration (GMA) provide exceptional audio quality and a smooth visual experience. The flexibility of platform options brings an array of new capabilities.

Features and Benefits of the Intel® Celeron® Processor

Features Benefits

Runs two independent processor cores in one physical package at the same frequency. Features up to 512 KB of shared L2 cache and 800 MHz Front Side Bus.

Intel® Dual-Core Processing

Intel® Wide Dynamic

Execution

Intel® Smart Memory Access

Improves execution speed and efficiency, delivering more instructions per clock cycle. Each core can complete up to four full instructions simultaneously.

Optimizes the use of the data bandwidth from the memory subsystem to accelerate out-of-order execution. A newly designed prediction mechanism reduces the time in-flight instructions have to wait for data. New prefetch algorithms move data from system memory into fast L2 cache in advance of execution. These functions keep the pipeline full, improving instruction throughput and performance.

Intel® Advanced Smart Cache The shared L2 cache is dynamically allocated to each processor core, based on workload. This efficient, dual-core-optimized implementation increases the probability that each core can access data from the fast L2 cache, significantly reducing latency to frequently used data and improving performance.

Intel® Advanced Digital

Media Boost

Accelerates the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the performance on a broad range of applications, including video, audio, image, and photo processing, and multimedia, encryption, financial, engineering, and scientific applications. The 128-bit SSE instructions are now issued at a throughput rate of one per clock cycle, effectively doubling execution speed on a per clock basis over previous generation processors.

Intel® 64 1 Architecture

Execute Disable Bit

Intel®-Designed Thermal

Solution for Boxed

An enhancement to Intel® 32-bit architecture that allows the processor to access larger amounts of memory. With appropriate 64-bit supporting hardware and software, platforms based on an Intel processor supporting Intel® 64 architecture enable the use of extended virtual and physical memory.

Provides enhanced virus protection when deployed with a supported operating system. The Execute Disable Bit marks memory as executable or non-executable, allowing the processor to raise an error to the operating system. If malicious code attempts to run in non-executable memory, the malicious code is prevented from infecting the system.

Intel boxed processors ship with a thermal solution specifically for this processor, designed for maximum thermal and acoustic performance.

1 64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance will vary depending on your hardware and software configurations. Consult with your system vendor for more information.

2 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.
