A4-4000 Details

As of March 2026, the AMD A4-4000 remains a relic from the early days of modern mainstream computing, having been released in May 2013. Built on AMD's Richland architecture and fabricated on a 22 nm process by GlobalFoundries, this dual-core desktop processor is now more than a decade old. Despite its age, the A4-4000 still serves as a baseline for entry-level systems, particularly in budget builds or legacy devices where integrated graphics and low power consumption are prioritized over performance. With a 35 W TDP and a socket FM2 interface, it reflects the efficiency-focused designs of its era, though it lacks the modern features found in contemporary CPUs.

The A4-4000 operates at a base clock of 1.9 GHz and features a locked multiplier, which limits overclocking potential. It includes 1 MB of L2 cache and supports DDR3 memory at speeds up to 1333 MT/s in dual-channel mode, providing modest memory bandwidth of 21.3 GB/s. The processor integrates the Radeon HD 7480D GPU, which runs at 650 MHz and can boost to 1 GHz, supporting up to three displays and offering basic multimedia and light gaming capabilities. While it supports a range of modern instruction sets—such as AVX, SSE4.2, and AMD-V—it does not include Hyper-Threading or advanced virtualization features found in later models.

In benchmark testing, the A4-4000 achieves a single-core score of 4131, placing it at #1647 out of 2060 processors, and a multicore score of 4295, ranking #1770. Its overall score of 4197 positions it at #1680, indicating that it is significantly outpaced by nearly every modern CPU. While it competes with older dual-core processors like the Core 2 Duo and Pentium G645, it falls well behind current mid-range and high-end chips. The top 50 processors in each category, such as the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, achieve scores over 8,000, highlighting the vast technological leap over the past decade.

The A4-4000’s performance is best suited for basic productivity tasks, web browsing, and media playback. It is not ideal for multitasking, content creation, or modern gaming due to its limited core count, low clock speeds, and outdated integrated graphics. However, its low power consumption and cost-effectiveness make it viable for lightweight applications or as a replacement in older systems. As of 2026, the A4-4000 serves more as a historical benchmark than a practical choice for new builds, representing a bygone era of computing where integrated solutions were sufficient for everyday use.
