A6-4455M Details

As of March 2026, the AMD A6-4455M remains a relic from an earlier era of mobile computing, having been launched in May 2012 as part of AMD's Trinity lineup. While its performance is now well behind modern processors, it still holds relevance in niche scenarios where power efficiency and basic functionality are prioritized over raw speed. Designed for mobile devices, the A6-4455M features a dual-core architecture built on a 32 nm process with a die area of 246 mm² and 1.3 billion transistors. Manufactured by GlobalFoundries under AMD's design, the chip operates at a base frequency of 1.3 GHz with a turbo boost up to 1.86 GHz, supported by 2 MB of L2 cache and a 64-bit instruction set. It is packaged in a BGA2 format and uses the Socket FP2 interface, typical of low-power mobile platforms of its time.

The A6-4455M integrates Radeon HD 7500G graphics, offering a base frequency of 350 MHz and a burst frequency of 1 GHz, capable of driving up to two displays. It supports dual-channel DDR3 memory up to 1333 MT/s, with a maximum system memory of 16 GB and a peak memory bandwidth of 21.3 GB/s. With a TDP of just 17 W, the processor excels in energy efficiency, making it suitable for lightweight laptops and netbooks that emphasize battery life. The integrated GPU supports hardware virtualization, AVX, AVX2, and other modern instruction sets, enabling basic multimedia and light productivity tasks.

In benchmark testing, the A6-4455M scores 3,985 in the overall Passmark rating, placing it at #1905 out of 2060 processors. Its single-core performance scores 3,809, ranking #1882, while its multicore score of 4,249 places it at #1907. These results show that while the A6-4455M can still handle entry-level tasks, it lags significantly behind contemporary CPUs, even in the lower end of the market. For example, it is outperformed by several modern Celeron and Pentium models, such as the Celeron N3060 and Pentium 987, both of which achieve higher scores despite being more recent. The processor's strongest performance category is single-core, where it competes with older dual-core chips like the Core i3-2375M, but its multicore performance is notably weaker, highlighting its limited scalability.

Despite its age, the A6-4455M remains a viable option for users requiring a low-power, budget-friendly solution for basic computing tasks such as web browsing, office applications, and media playback. Its integrated graphics and low TDP make it a reasonable choice for lightweight devices where extended battery life is a priority. However, for demanding applications or modern software, the processor's limitations in processing power and memory bandwidth render it obsolete. In today’s landscape, where high-end CPUs like the Ryzen Threadripper PRO 9995WX exceed 12,000 in multicore performance, the A6-4455M stands as a testament to the rapid evolution of mobile computing, offering a glimpse into a past era of efficient but modest performance.
