Athlon II M320 Details

Ranking #1882 of 2060 in overall performance, the Athlon II M320 represents a mid-tier entry in AMD's legacy lineup, designed for basic computing tasks in the early 2010s. While it no longer competes with modern processors, its 2.26 GHz base clock and 2.3 GHz turbo frequency reflect its position as a dual-core, quad-threaded CPU built on a 45 nm process. This processor, launched during a time when integrated graphics were becoming more common, is part of a broader era where AMD focused on energy efficiency and affordability for mainstream users.

The Athlon II M320 operates on the PGA478 socket, a pin grid array design that was widely used in desktop motherboards of its time. It supports DDR3L 1333 memory with a maximum capacity of 8 GB and a memory bandwidth of 21.3 GB/s, which was adequate for office productivity, media playback, and light multitasking. The 65 W TDP indicates a focus on thermal efficiency, allowing it to run quietly in small form-factor systems without requiring aggressive cooling.

Despite its age, the processor includes a range of modern features for its time, such as SSE4.1, SSE4.2, AVX2, AES encryption, and x86-64 support. It also supports Hyper-Threading, enabling it to handle multiple threads simultaneously, and includes technologies like EIST and TXT for power management and security. However, its performance is limited by its dual-core design and lack of advanced cache hierarchies, with only 1 MB of L2 cache shared between cores.

The integrated GPU, labeled as HD Graphics, runs at a base frequency of 313 MHz with a burst frequency of 854 MHz and supports up to two displays. While not suitable for gaming or intensive graphics workloads, it provides basic visual output for everyday use. The processor’s single-core score of 3810 places it just below the top 10% of its generation, while its multicore score of 4302 reflects modest scaling across two cores.

Compared to contemporary CPUs, the Athlon II M320 is outperformed by models like the Celeron J1900 and A6-9220, both of which offer higher scores due to improved architecture and better memory handling. However, it holds its own against older processors such as the Celeron E1500 and Phenom X4 9550, which were released during a similar period. As of March 2026, the Athlon II M320 remains a relic of an earlier computing era, best suited for legacy systems, low-cost desktops, or embedded applications where power consumption and cost are prioritized over raw performance.
