Pentium III

The Pentium III processor, shown in Figure 3.26, was released in February 1999 and introduced several new features to the P6 family. It is essentially the same core as a Pentium II with the addition of SSE instructions and integrated on-die L2 cache in the later versions. SSE consists of 70 new instructions that dramatically enhance the performance and possibilities of advanced imaging, 3D, streaming audio, video, and speech-recognition applications.

Originally based on Intel’s advanced 0.25-micron CMOS process technology, the PIII core started out with more than 9.5 million transistors. In late 1999, Intel shifted to a 0.18-micron process die (code-named Coppermine) and added 256KB of on-die L2 cache, which brought the transistor count to 28.1 million. The last version of the Pentium III (code-named Tualatin) uses a 0.13-micron process and has 44 million transistors; motherboards made before the Tualatin-core versions of the Pentium III generally do not support this processor because of logical pinout changes. The Pentium III was manufactured in speeds from 450MHz through 1.4GHz, as well as in server versions with larger or faster cache known as the Pentium Xeon. The Pentium III also incorporates advanced features such as a 32KB L1 cache and either half-core speed 512KB L2 cache or full-core speed on-die 256KB or 512KB L2 with cacheability for up to 4GB of addressable memory space. The PIII also can be used in dual-processing systems with up to 64GB of physical memory. A self-reportable processor serial number gives security, authentication, and system management applications a powerful new tool for identifying individual systems. Because of privacy concerns when the processor was released, you can disable this feature in the system BIOS on most systems that use the Pentium III or Celeron III processors.

Pentium III processors were made available in Intel’s SECC2 form factor, which replaced the more expensive older SECC packaging. The SECC2 package covers only one side of the chip and allows for better heatsink attachment and less overall weight. Architectural features of the Pentium III processor include the following:

  • Streaming SIMD extensions (SSE)— Seventy new instructions for dramatically faster processing and improved imaging, 3D streaming audio and video, web access, speech recognition, new user interfaces, and other graphics and sound-rich applications.

  • Intel processor serial number— Serves as an electronic serial number for the processor and, by extension, its system or user. You can enable or disable this feature as desired in the BIOS Setup. The serial number enables the system/user to be identified by company internal networks and applications. You can use the processor serial number in applications that benefit from stronger forms of system and user identification, such as the following:

    • Applications using security capabilities— Managed access to new Internet content and services; electronic document exchange.

    • Manageability applications— Asset management; remote system load and configuration.

Although the initial release of Pentium III processors was made in the improved SECC2 packaging, Intel later switched to the FC-PGA package, which is even less expensive to produce and enables a more direct attachment of the heatsink to the processor core for better cooling. The FC-PGA version plugs into Socket 370 but can be used in Slot 1 with a slotket adapter.

All Pentium III processors have either 512KB or 256KB of L2 cache, which runs at either half-core or full-core speed. Pentium III Xeon versions have 512KB, 1MB, or 2MB of L2 cache that runs at full-core speed. The Pentium III Xeon is a more expensive version of the Pentium III designed for servers and workstations. All PIII processor L2 caches can cache up to 4GB of addressable memory space and include ECC capability.

Videogame consoles

"Coppermine-128" (180 nm)

A modified version of Coppermine was developed for Microsoft's Xbox game console. The only significant change was that the chip lost half of its L2 cache, dropping it down to 128 KB. Unlike the Celeron Coppermine variant with the same size L2 cache, Xbox's Coppermine core kept all of its 8-way L2 cache associativity from the Pentium III. This meant that the Xbox CPU's L2 cache was more efficient than Celeron's. The Xbox CPU was manufactured onto the same Micro-PGA2 packaging as notebook chips.

  • All models support: MMX, SSE
  • The L2 cache runs at 100% cpu speed
