About Intel Pentium III 1133S
The Intel Pentium III 1133S chip from Intel marks the final high‑frequency iteration of the classic P6 micro‑architecture. Built on a 130 nm process, it retains the superscalar, out‑of‑order execution pipeline that defined the Pentium III family. Its base clock runs at 1.133 GHz, and while the part does not feature a dynamic turbo boost, the fixed frequency was a sweet spot for legacy software in the early 2000s. The single‑core, single‑thread design leverages a 133 MHz front‑side bus to communicate with the rest of the system. Despite its age, the core’s 8‑stage pipeline and branch prediction logic still illustrate the engineering milestones that paved the way for modern CPUs.
Thermal design is modest, with a 29 W TDP that fits comfortably within the cooling envelopes of standard desktop heatsinks of the era. The cache hierarchy consists of a 32 KB L1 instruction cache, a 32 KB L1 data cache, and a 256 KB L2 cache located on the die, delivering low‑latency access for the era’s typical workloads. The 1133S model from Intel’s Pentium III line was aimed at budget‑conscious desktops, office PCs, and entry‑level workstations that required reliable integer performance without the cost of dual‑core designs. Its Socket 370 interface allowed easy integration into existing motherboards, making upgrades straightforward for users still on older platforms. For retro enthusiasts and legacy software developers, this processor remains a reference point for measuring the evolution of single‑thread efficiency.
