A6-3420M Details

Ranked #1730 of 2060 in overall performance, the AMD A6-3420M presents a modest benchmark result that reflects its position as a budget-oriented mobile processor from the early 2010s. With an overall score of 4163, it trails behind modern processors by a significant margin—especially when compared to top-tier CPUs like the Ryzen Threadripper PRO 9995WX, which scores over 9,400. This disparity underscores the A6-3420M's age and its limited relevance in today’s computing landscape. However, in its time, the chip offered a balance between integrated graphics and general-purpose performance for lightweight tasks.

The A6-3420M is built on AMD’s Llano architecture, manufactured on a 22 nm process node, and features a dual-core design with no simultaneous multithreading, limiting its ability to handle multi-threaded workloads efficiently. Base clock speed sits at 1.8 GHz, with a turbo frequency of 2.0 GHz, allowing for brief performance boosts under load. It operates within a 35 W TDP, making it suitable for thin-and-light laptops where power efficiency is critical. The processor supports DDR3 memory at up to 1600 MHz in a dual-channel configuration, with a maximum memory capacity of 32 GB.

On the graphics side, the A6-3420M includes the Radeon HD 6520G integrated GPU, which runs at a base frequency of 650 MHz and can boost to 1.0 GHz. While not capable of modern gaming or GPU-intensive workloads, this integrated solution was sufficient for basic multimedia playback and light graphics tasks during its era. It supports up to three display outputs, making it versatile for dual-screen setups in entry-level mobile devices.

The A6-3420M supports a range of technologies, including AMD-V virtualization, SSE4.1, SSE4.2, and AVX2 instruction sets, ensuring compatibility with a wide array of software. However, its lack of ECC memory support and a locked clock multiplier restrict its appeal for advanced users or server environments. Despite these limitations, the processor’s integrated design and low power consumption made it a popular choice in budget laptops.

In single-core performance, the A6-3420M scores 4037, placing it just below mid-tier mobile CPUs of its time, such as the Core i3-4012Y. Its multicore performance of 4351 indicates that it can handle basic multitasking but struggles with heavily threaded applications. While it outperforms older dual-core processors like the Core 2 Duo E8600, it falls short when compared to newer mobile APUs from the same period.

As of March 2026, the A6-3420M is best suited for legacy systems or light-duty computing tasks such as web browsing, document editing, and media playback. Its age and performance profile make it unsuitable for modern applications, gaming, or professional workloads. For users requiring more power, upgrading to a modern processor would be necessary, but for basic functionality in older devices, the A6-3420M remains a functional, albeit outdated, option.
