About: PiFastPiFast 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Although it is quite outdated compared to modern benchmarks, PiFast is still used today as a simple and effective testing tool, especially among the overclocking community and hardware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.
The Intel Core i5-1135G7 is a quad-core mobile processor introduced in late 2020 as part of Intel’s 11th generation Tiger Lake lineup. Designed for thin and light laptops, this CPU delivers a strong balance of performance, power efficiency, and modern features, making it a popular choice for both casual users and professionals. Featuring 4 cores and 8 threads through Hyper-Threading Technology, it operates at a base clock of 2.4 GHz and can reach up to 4.2 GHz with Intel Turbo Boost, ensuring smooth multitasking and snappy responsiveness for day-to-day applications.
Built using Intel’s advanced 10nm SuperFin process, the i5-1135G7 offers improved efficiency and thermal performance over previous 14nm generations. With a configurable TDP ranging from 12W to 28W, OEMs can adjust the performance envelope depending on the device’s thermal design. The standout feature of this processor is its integrated Intel Iris Xe Graphics, equipped with 80 Execution Units and a dynamic frequency of up to 1.3 GHz. Compared to older Intel UHD Graphics, Iris Xe brings a massive leap in performance, capable of handling casual gaming, 4K video playback, and GPU-accelerated workloads like video rendering or image editing.
In benchmark tests such as Cinebench R23, the i5-1135G7 scores around 5661 points (multi-core) and 1334 points (single-core), showcasing excellent performance for a low-power chip. These scores reflect its capability to handle modern productivity software, web-based workflows, and even creative tools like Adobe Photoshop or Premiere Pro though for heavier workloads, a higher-end CPU may still be recommended.
Real-world performance testing was done on a Lenovo IdeaPad Slim 3i 14ITL6, a budget-to-midrange laptop equipped with 12GB DDR4 3200MHz dual-channel memory (8+4 configuration). This setup, combined with Windows 10 and Windows 11 22H2, allows the i5-1135G7 to fully utilize its integrated GPU and high-speed memory interface for a snappy and responsive user experience.
Whether you're a student, a professional, or a casual user looking for a capable, energy-efficient processor, the Intel Core i5-1135G7 stands out as one of the best value choices in the ultrabook category.
