Pentium III
For the Pentium III, the successor to the Pentium II, the codename for the CPU core was Coppermine. With Coppermine technology, structure widths of 0.18 µm and 0.13 µm could be realized. In addition, this technology was the first to achieve the clock frequency of 1 GHz, which was 450 MHz in standard technology.
The Pentium III consists of 9.5 million transistors and is thus classified as Super Large Scale Integration( SLSI) in terms of integration technology. It has two Level 1 caches of 16 KB and a Level 2 cache of 512 kilobytes (KB) to 2 megabytes ( MB).
The address space for the physical memory is 64 gigabytes( GB), that of the virtual memory 64 terabytes( TB). The Pentium III is operated in the CPU socket 370.
The Pentium III has a more comprehensive instruction set primarily for multimedia applications and uses the SIMD computing architecture, which allows for more efficient instruction processing. This technology, which allows graphics operations to be performed with a single instruction, significantly expands the existing instruction set.
Just like the Pentium II, there is also a special version of the Pentium III for high-end applications: the Xeon, which is equipped with a Slot 2 interface and has a Level 2 cache of up to 2 MB, which is operated at the processor's clock frequency.
