Software: GPUPI for CPU - 100M

Score: 1min 544ms

GPUPI for CPU – 100M is a benchmark designed to measure the performance of a processor (CPU) in performing intensive mathematical calculations, specifically in calculating the value of π (pi) to 100 million decimal places. This benchmark uses the BBP (Bailey–Borwein–Plouffe) algorithm, which has been optimized for high performance on modern systems, and supports various CPU architectures and instructions.

Although GPUPI was originally developed for GPUs, the “for CPU” version enables testing of numerical processing performance using the full CPU core. This test is highly demanding and is often used to evaluate system stability, single-core performance, and multi-core performance of a CPU. In the 100M configuration, this benchmark provides a moderate-to-heavy workload that adequately represents system performance in scientific calculation scenarios, data analysis, and encoding tasks.

This benchmark automatically detects and utilizes all available threads in the system to accelerate the computation process, but it can also be run in a limited thread mode for more specific testing. The final score is displayed in units of time (seconds), where a lower number indicates better performance.

GPUPI for CPU – 100M is also a popular choice in the overclocking community due to its consistency in delivering precise results and its sensitivity to changes in frequency and system stability. With its heavy and stable workload, this benchmark can also be used for stress testing and system validation in extreme configurations.

Additionally, GPUPI supports integration with BenchMate, which provides score verification and protection against benchmark result manipulation, making it a reliable tool for competitions and professional hardware evaluations.

Overall, GPUPI for CPU – 100M is an ideal benchmark for measuring a processor's arithmetic capabilities under real-world conditions, particularly in tasks that heavily rely on numerical performance and system stability.
