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 Celeron B815, released in 2012, is an entry-level mobile processor based on the Sandy Bridge architecture. Designed for budget laptops, it features 2 cores and 2 threads with a fixed clock speed of 1.6 GHz. The processor does not support Turbo Boost or Hyper-Threading, limiting its multitasking capabilities.
Manufactured using 32nm process technology, the Celeron B815 has a TDP of 35W, which is relatively high for a low-end mobile CPU. This higher thermal output typically results in shorter battery life and more heat generation compared to modern low-power processors.
For graphics, the processor is equipped with Intel HD Graphics 2000, which runs at a base frequency of 650 MHz and can boost up to 1.0 GHz. While not suitable for gaming, this integrated GPU handles basic visual tasks like 720p video playback, simple animations, and light graphical workloads adequately.
In everyday usage, the Celeron B815 performs best with lightweight applications such as web browsing, word processing, and playing standard-definition videos. However, it struggles with modern operating systems, multitasking, and heavier workloads due to its limited core/thread count and lack of advanced CPU features.
