Intel® Pentium® III Processor 866 MHz, 256K Cache, 133 MHz FSB

Launch Date

The date the product was first introduced.

Lithography

Lithography refers to the semiconductor technology used to manufacture an integrated circuit, and is reported in nanometer (nm), indicative of the size of features built on the semiconductor.

Recommended Customer Price

Recommended Customer Price (RCP) is pricing guidance only for Intel products. Prices are for direct Intel customers, typically represent 1,000-unit purchase quantities, and are subject to change without notice. Prices may vary for other package types and shipment quantities. If sold in bulk, price represents individual unit. Listing of RCP does not constitute a formal pricing offer from Intel.

# of Cores

Cores is a hardware term that describes the number of independent central processing units in a single computing component (die or chip).

Processor Base Frequency

Processor Base Frequency describes the rate at which the processor's transistors open and close. The processor base frequency is the operating point where TDP is defined. Frequency is measured in gigahertz (GHz), or billion cycles per second.

Cache

CPU Cache is an area of fast memory located on the processor. Intel® Smart Cache refers to the architecture that allows all cores to dynamically share access to the last level cache.

Bus Speed

A bus is a subsystem that transfers data between computer components or between computers. Types include front-side bus (FSB), which carries data between the CPU and memory controller hub; direct media interface (DMI), which is a point-to-point interconnection between an Intel integrated memory controller and an Intel I/O controller hub on the computer’s motherboard; and Quick Path Interconnect (QPI), which is a point-to-point interconnect between the CPU and the integrated memory controller.

TDP

Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload. Refer to Datasheet for thermal solution requirements.

VID Voltage Range

VID Voltage Range is an indicator of the minimum and maximum voltage values at which the processor is designed to operate. The processor communicates VID to the VRM (Voltage Regulator Module), which in turn delivers that correct voltage to the processor.

Embedded Options Available

Embedded Options Available indicates products that offer extended purchase availability for intelligent systems and embedded solutions. Product certification and use condition applications can be found in the Production Release Qualification (PRQ) report. See your Intel representative for details.

Sockets Supported

The socket is the component that provides the mechanical and electrical connections between the processor and motherboard.

T_CASE

Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS).

Intel® Turbo Boost Technology ^‡

Intel® Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it, and increased energy efficiency when you don’t.

Intel® Virtualization Technology (VT-x) ^‡

Intel® Virtualization Technology (VT-x) allows one hardware platform to function as multiple “virtual” platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions.

Instruction Set

An instruction set refers to the basic set of commands and instructions that a microprocessor understands and can carry out. The value shown represents which Intel’s instruction set this processor is compatible with.

Boxed Processor

Intel Authorized Distributors sell Intel processors in clearly marked boxes from Intel. We refer to these processors as boxed processors. They typically carry a three-year warranty.

What is the difference between Boxed and Tray Processors?

Tray Processor

Intel ships these processors to Original Equipment Manufacturers (OEMs), and the OEMs typically pre-install the processor. Intel refers to these processors as tray or OEM processors. Intel doesn't provide direct warranty support. Contact your OEM or reseller for warranty support.
