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.
Released in mid-2011, the AMD A6-3400M is a mobile processor from the Llano family designed for the mid-range laptop segment. It has 4 cores and 4 threads with a base speed of 1.4 GHz that can increase to 2.3 GHz thanks to AMD's Turbo Core technology. Carrying a 32nm fabrication process, the A6-3400M offers good power efficiency with a TDP of 35W, making it a popular choice among conventional laptop users at the time. The main advantage of this processor lies not only in having enough cores for light multitasking, but also in the integration of an onboard GPU, the AMD Radeon HD 6520G. This GPU has 320 shader cores based on the Terascale 2 architecture, which is capable enough to run light graphics applications to older games with low resolution and graphics quality settings. The combination of CPU and GPU in one chip is designed to provide a balance between computing and graphics performance in one energy-efficient package.
In terms of performance, the A6-3400M can handle everyday computing needs such as browsing the internet, watching videos, listening to music, typing documents, and other light productivity tasks. However, in heavier usage scenarios or multitasking with many applications open at once, its performance starts to show limitations, especially when combined with a small RAM capacity such as 2GB. When compared to the same generation of Intel Core i3 processors, the A6-3400M does lag behind in single-thread performance, which is an important aspect for running modern applications that are not fully optimized for multi-core. In tests on a Lenovo Sabine B475 device with 2GB DDR3 RAM and Windows 7 operating system, the A6-3400M's performance showed that it is still quite responsive for light use, although it is no longer ideal for today's heavier workloads. Even so, the A6-3400M is still an attractive option for users who want a budget laptop with basic multimedia capabilities and a decent user experience for everyday needs.
