About: PiFastPiFast is a simple benchmark application designed to measure a processor's speed in performing heavy floating-point computations by calculating the value of π (pi) to millions of decimal digits. It works by running a fast algorithm based on the FFT (Fast Fourier Transform) to speed up calculations, and is commonly used to test the stability and performance of single-threaded CPUs. As PiFast only taxes a single processor core and relies entirely on the CPU's computing power and memory efficiency, the resulting times are highly sensitive to clock speed, CPU architecture, RAM latency, and system optimization. PiFast is popular among overclockers as a quick tool to measure performance improvements after overclocking.
The Intel Core i7-11700 is a powerful desktop processor released in Q1 2021, as part of Intel’s 11th Generation Rocket Lake family. Designed for enthusiasts, gamers, and content creators, this CPU offers a solid balance of single-threaded and multi-threaded performance. It features 8 physical cores and 16 threads, making it ideal for tasks such as gaming, streaming, 4K video editing, 3D rendering, and heavy multitasking.
With a base clock speed of 2.5 GHz and a maximum turbo frequency of up to 4.9 GHz, the i7-11700 delivers strong performance out of the box. The processor is built on Intel’s 14nm process node, but with significant architectural improvements over the previous generation, notably higher IPC (Instructions Per Cycle) thanks to the Cypress Cove core design. Despite using the older 14nm process, these architectural upgrades allow the i7-11700 to compete closely with AMD's Ryzen 7 5000-series CPUs in many workloads.
The TDP (Thermal Design Power) of the Core i7-11700 is rated at 65W, making it relatively efficient for a high-end CPU. However, under sustained heavy loads, especially in systems with aggressive power limits or PL1/PL2 settings, actual power consumption can be much higher—so a decent cooling solution is recommended for consistent performance.
For integrated graphics, the i7-11700 is equipped with Intel UHD Graphics 750, based on the Xe architecture. It supports up to 4K resolution at 60Hz, HEVC/VP9 decode/encode, and can handle light gaming or display output without the need for a discrete GPU. Still, for users focused on gaming or GPU-accelerated workloads, pairing this processor with a dedicated graphics card is highly recommended.
