Score: 22min 28sec 335ms

GPUPI for CPU – 1B is a heavy-duty computational benchmark designed to measure the capability of a processor (CPU) in solving extreme mathematical calculations, by calculating the value of π (pi) to 1 billion decimal places. This benchmark uses the highly efficient BBP (Bailey–Borwein–Plouffe) algorithm, which is well-suited for leveraging modern CPU architectures, both in terms of single-thread and multi-thread performance.

In this test, GPUPI pushes the CPU to its limits with extremely complex and intensive numerical workloads. Compared to the 100M version, the 1B configuration offers a significantly heavier workload and longer duration, making it ideal for assessing long-term performance, system stability, and cooling efficiency. The benchmark results are displayed in units of time (seconds), where a lower score indicates that the CPU can complete the task faster.

This benchmark automatically utilizes all available cores and threads to provide an accurate picture of the CPU's parallel computing capabilities, making it highly relevant for real-world applications such as scientific simulations, video encoding, data mining, and engineering software.

GPUPI for CPU – 1B is also widely used in the overclocking community as an extreme stress test tool and for validating system stability at high frequencies. The accuracy of the results and sensitivity to system configuration changes make this benchmark highly valued in testing high-end hardware performance.

With support for BenchMate integration, GPUPI also ensures the security and authenticity of scores, making it a trusted and widely used benchmarking tool in competitions and professional hardware reviews.

In summary, GPUPI for CPU – 1B is a highly demanding and accurate numerical CPU performance benchmark, suitable for testing the maximum limits of modern computing systems.
