Pentium III
<processor, Intel> The
microprocessor that was
Intel Corporation's successor to the
Pentium II, introduced in 1999 with a 500
MHz clock rate.
The Pentim III is very similar to the Pentium II in architecture.
Its external
bus can be clocked at 100 or 133 MHz, it can have up to 512
KB of
secondary cache, and it comes in various packages including SECC2 and
FC-PGA.
The Pentium III has a
P6 Dynamic Execution microarchitecture, a multi-transaction system bus, and
MMX, like the Pentium II.
It adds Dual Independent Bus (DIB) Architecture, the Intel Processor Serial Number, Internet
Streaming SIMD Extensions, 70 new instructions. Some versions also include an Advanced Transfer Cache and Advanced System Buffering.
When Intel released a 1.13
GHz version of the Pentium III processor using a 0.18
micron fabrication process on 2000-07-31, it was the world's highest performance microprocessor for PCs.
