A4-3400 Details

The AMD A4-3400, launched in September 2011, is a desktop processor built on the Llano architecture and designed for budget-oriented systems. Despite being over a decade old, it remains notable for its integrated Radeon HD 6410D graphics, which allowed it to serve as a cost-effective solution for users who did not require a discrete GPU. The processor operates at a base frequency of 1.9 GHz and features two cores with two threads, making it suitable for light multitasking and basic productivity workloads. Its 22 nm manufacturing process and 35 W TDP reflect the efficiency-focused design of its era, though modern standards have significantly outpaced its performance and thermal design.

The A4-3400 integrates 512 KB of L2 cache per core and supports dual-channel DDR3 memory with a maximum rated speed of 1866 MT/s, though actual performance is limited by its single-core and dual-core design. It connects via the FCPGA988 socket and supports PCIe 2.0, enabling compatibility with contemporary peripherals of its time. The integrated Radeon HD 6410D GPU runs at a base frequency of 650 MHz and can reach a burst frequency of 1000 MHz, offering basic multimedia and gaming capabilities on low-end monitors. The processor supports up to 16 GB of memory and three display outputs, providing modest multimedia flexibility.

In terms of features, the A4-3400 supports a range of instruction sets including MMX, SSE, SSE2, SSE3, SSE4.1, SSE4.2, AVX2, AES, and AMD-V, enabling efficient handling of common workloads and virtualization tasks. However, it lacks support for modern technologies like Hyper-Threading or simultaneous multithreading, which limits its ability to scale in multi-threaded applications. Its performance, as reflected in benchmark data, is now firmly in the lower tier of modern CPUs. The processor scores 4228 overall, placing it at #1628 among 2060 CPUs, with single-core and multicore scores of 4162 and 4327, respectively.

When compared to contemporary processors, the A4-3400 falls behind significantly in both single-core and multicore performance. It ranks below CPUs like the Intel Core i3-4005U and AMD Athlon II X3 400e, which offer similar or better performance despite being released years later. Its multicore performance, in particular, is outpaced by nearly every modern processor, with only low-power devices like the Intel Celeron N4000 and Atom Z3740 showing comparable scores. While the A4-3400 was competitive in its time for basic computing tasks, its relevance today is limited to legacy systems or niche retro builds. As of March 2026, it serves as a historical benchmark of early 2010s integrated computing design.
