PiFast is a classic benchmark application designed to measure processor performance in performing intensive mathematical calculations, particularly in calculating the value of pi (π) to millions of digits. This benchmark is renowned for being lightweight, fast to run, and highly accurate in reflecting the capabilities of single-thread CPUs, making it a popular choice among overclockers and system performance testers since the early days of processors.

In PiFast testing, the system is tasked with calculating the value of pi using a fast algorithm based on high-precision mathematics. The faster the time achieved, the higher the performance of the tested CPU. Since PiFast runs on a single core (single thread), this benchmark is highly relevant for measuring the efficiency of a single core in both modern and older processors.

Features and Advantages of PiFast:

• Very lightweight and does not require installation.
• Ideal for testing system stability after overclocking.
• Focuses on single-thread performance, an important indicator in gaming and lightweight application performance.
• Provides test results in seconds, suitable for quick and repetitive testing.
• Compatible with various Windows versions, including older systems.

Although it is quite outdated compared to modern benchmarks, PiFast is still used today as a simple and effective testing tool, especially among the overclocking community and hardware enthusiasts who want to validate performance without running heavy benchmarks.
