A8-4555M Details

As of March 2026, the AMD A8-4555M stands as a relic of an earlier era in mobile computing, having been released in September 2012. Despite its age, it remains a notable example of AMD's early integrated graphics strategy for laptops, built on the Trinity architecture and targeting the mobile market. With a 65 W TDP and a 65 nm process, the A8-4555M was designed for power efficiency, a key factor in its adoption for lightweight notebooks of its time. While its performance is now far behind modern processors, it still holds relevance for understanding the evolution of integrated computing and low-power mobile CPUs.

The processor features a quad-core design, with two physical cores and two threads, a configuration enabled by Simultaneous Multithreading (SMT). It operates at a base clock of 2.6 GHz and can boost up to 2.3 GHz, a configuration that appears inconsistent with modern naming conventions but reflects the design constraints of its era. The chip includes 4 MB of L2 cache and supports DDR3L 1333 memory across a dual-channel interface, enabling a maximum memory bandwidth of 21.3 GB/s. It uses the PLGA775 socket and is compatible with PCIe 2.0, providing connectivity for peripherals and storage devices.

Integrated graphics are a standout feature, with the Radeon HD 7600G GPU capable of reaching a burst frequency of 854 MHz. This GPU supports up to two displays and offers a decent level of multimedia performance for its time, though it falls far short of today's standards. The A8-4555M also supports a range of advanced instruction sets, including AVX, AVX2, AES, and FMA3, enabling efficient performance in compute-heavy applications such as video encoding and scientific simulations.

In benchmark testing, the A8-4555M scores 3897 overall, placing it at #1962 out of 2060 processors in the database. Its single-core performance is rated at 3643, ranking #1966, while its multicore score of 4278 places it at #1826. These results indicate that the A8-4555M is significantly outperformed by modern processors, even in entry-level segments. For instance, it trails behind the Intel Core i5-650 and the AMD A4-3310MX in multicore performance, and is surpassed by the Atom x5-Z8500 and Pentium J2900 in single-core tasks. Its position in the rankings reflects its role as a mid-tier mobile processor from a decade ago.

Despite its outdated specifications, the A8-4555M remains useful for niche applications such as retro computing, embedded systems, or educational purposes. Its low power consumption and integrated graphics make it suitable for basic computing tasks, including web browsing, office productivity, and media playback. However, for modern workloads involving AI, gaming, or high-resolution content creation, it is no longer viable. As of 2026, it serves as a historical benchmark for the rapid advancement in CPU design and integrated graphics capabilities.
