AMD A4-4000

The AMD A4-4000 is a dual-core desktop processor built on the Piledriver architecture, codenamed Richland, and manufactured on GlobalFoundries’ 32 nm process. It targets the entry-level segment of the AMD Socket FM2 platform, integrating a Radeon HD 7480D graphics solution and a 65 W TDP class. This analysis relies strictly on the provided data, covering platform compatibility, workload suitability, power expectations, FAQs, and benchmark-derived interpretations of its positioning.

Platform and Compatibility

The AMD A4-4000 uses the AMD Socket FM2, a socket designed for Richland and Trinity-generation processors. This socket supports DDR3 memory exclusively, with a dual-channel memory bus that delivers a theoretical bandwidth of 21.3 GB/s. The processor itself has a base clock of 3.00 GHz and a boost clock of 3.20 GHz, with two cores and two threads. The L1 cache totals 96 KB, while the L2 cache is 1 MB (shared) — there is no L3 cache present in this design.

PCIe support is limited to Gen 2, which means the platform does not offer the bandwidth of newer PCIe generations, but it remains functional for basic discrete graphics and expansion cards from the same era. The memory controller does not support ECC, so error-correcting memory is not an option for this platform. The processor includes integrated Radeon HD 7480D graphics, making it a viable option for systems that do not require a separate graphics card. The multiplier is locked, so overclocking via multiplier adjustment is not possible; users would be limited to base clock adjustments on compatible motherboards, though the data does not specify those details.

The production status is end-of-life, indicating that this part is no longer actively manufactured. The part number is AD4000OKA23HLAD4000OKHLBOX, and the die size is 246 mm² with 1,303 million transistors. Upgrade path within the FM2 socket would depend on motherboard BIOS support, but the data does not list specific compatible processors beyond the A4-4000 itself. Given the end-of-life status, new purchases are unlikely, but used or existing systems can still utilize this chip for basic tasks.

Who Should Consider It

The AMD A4-4000 sits at the 50th percentile against all CPUs, according to the provided metric, which places it in the middle of the distribution — but that percentile is based on a benchmark score of zero, meaning the data shows no actual performance scores are available. With two cores and two threads at a modest clock speed, this processor is not designed for heavy multi-threaded workloads. Benchmark results, where available, would indicate that it handles light office productivity, web browsing, and document editing without strain, but the lack of a multi-core advantage means it will lag behind any modern quad-core or higher processor.

For gaming, the integrated Radeon HD 7480D graphics can handle very old or low-resolution titles, but the data does not provide any frame rate or game-specific metrics. The dual-channel memory bandwidth of 21.3 GB/s is a limiting factor for integrated graphics performance, as the CPU and GPU share the same memory bus. Content creation tasks such as video editing, 3D rendering, or compiling code would be severely constrained by the two threads and the lack of L3 cache. The processor is better suited for a basic home or office PC where the workload is light and intermittent.

The absence of nearestRivals data means no direct percentage comparisons can be made to other specific processors. However, the 50th percentile placement suggests that it is neither a bottom-tier nor a top-tier part; it is exactly average in the context of all CPUs tracked by this database, though that average is skewed by the fact that many newer, higher-core-count parts exist. For users with a Socket FM2 motherboard already on hand, this chip can serve as a low-cost drop-in replacement, but for new builds, the platform is obsolete.

Power and Thermals

The TDP is listed as 65 W, which places this processor in the mainstream desktop power class. A 65 W TDP does not require exotic cooling; a standard air cooler with a small heatsink and a 80-92 mm fan is typically sufficient, though the data does not specify cooler dimensions. The 32 nm process node from GlobalFoundries is relatively old, so power efficiency is not a strong point compared to modern nodes, but the 65 W figure is manageable for most power supplies.

The integrated graphics add to the thermal load, but since the TDP already accounts for the entire package, the cooling solution must handle both the CPU cores and the Radeon HD 7480D. A stock AMD cooler from the same era would be adequate, but aftermarket options with a larger surface area would reduce noise and temperatures. The locked multiplier means no enthusiast overclocking headroom, so the cooling requirement is not exacerbated by user modifications. The 65 W TDP also implies that the motherboard VRM requirements are modest, making inexpensive FM2 boards sufficient for this chip.

Given the end-of-life status, users are unlikely to find this processor in new retail packaging, but used markets may offer it at low prices. The thermal design allows for a compact system build, and the 246 mm² die size with 1,303 million transistors indicates a fairly large chip for a dual-core, which may contribute to heat density. Still, 65 W is a conservative figure, and the processor should run within safe temperatures under a basic cooler in a well-ventilated case.

Benchmark Performance

The benchmark data for the AMD A4-4000 is sparse: the benchmarks array is empty, the average benchmark score is zero, and the nearestRivals list is empty. This means no direct percentage deltas can be calculated against competing processors. The only performance-related metric is the percentileVsAllCpus value of 50, which indicates that this processor falls exactly at the median of all CPUs in the database. However, given the zero average score, this percentile is likely derived from a categorization rather than actual measured performance.

In the absence of scores, the architectural details provide a qualitative picture. A dual-core, dual-thread Piledriver design at 3.00-3.20 GHz is typical of entry-level processors from the early 2010s. The 1 MB shared L2 cache and no L3 cache limit the amount of data that can be held close to the cores, which impacts workloads with large working sets. The memory bandwidth of 21.3 GB/s is low by modern standards, further constraining performance in memory-intensive tasks.

Compared to a hypothetical modern quad-core with higher clocks and larger caches, the A4-4000 would be significantly slower, but the nearestRivals field provides no names or deltaPct values to quantify that gap. The 50th percentile suggests that in the database’s historical record, this chip is not an outlier — it is a typical low-end part. For users with the FM2 platform, the performance is what it is: adequate for basic tasks, but not competitive with even mid-range processors from later generations.

Single-Thread vs Multi-Thread Behavior

The A4-4000 has 2 cores and 2 threads, meaning it cannot leverage simultaneous multithreading. Single-thread performance is driven by the 3.00 GHz base and 3.20 GHz boost clocks, which are respectable for the Piledriver architecture but lag behind newer designs with higher instructions per clock. The L1 cache of 96 KB is split between instructions and data, but the data does not specify the exact split; the L2 cache of 1 MB shared between the two cores is small, which can cause contention when both cores access the same cache region.

Multi-thread performance is limited by the core count. Only two threads can run concurrently, so any application that scales beyond two threads will see no benefit from additional cores — there are none. The dual-channel memory bus helps with bandwidth, but the lack of L3 cache means that data must be fetched from main memory more often, increasing latency. In single-threaded workloads like older games or office apps, the boost clock of 3.20 GHz provides a modest speed advantage over the base clock, but the architecture’s efficiency is the limiting factor.

For real-world usage, the single-thread behavior is what users will experience most often in daily tasks like opening files or browsing, where the processor can ramp to boost. Multi-thread tasks such as video encoding or running multiple virtual machines will suffer due to the thread limitation. The 50th percentile placement reflects that this is an average part, but that average is against all CPUs ever tracked, including many with far more cores. The data does not provide specific single-thread or multi-thread benchmark scores, so the analysis remains qualitative, grounded in the core count, clock speeds, and cache sizes listed.
