About AMD A9-9420e SoC
The AMD A9-9420e SoC is a mobile processor from AMD, built on the Excavator architecture with the Stoney Ridge codename. It features 2 cores and 2 threads, with a base clock of 1.80 GHz and a boost clock of 2.70 GHz. This SoC targets the AMD Socket FT4 platform and carries a TDP of 6W. The production status is end-of-life, and it was released on 2016-05-30. The benchmark database lists an average benchmark score of 0 and a percentile rank of 50 among all CPUs, with no individual benchmark entries recorded.
Benchmark Performance
The fact pack provides no discrete benchmark scores for the A9-9420e, as the benchmarks array is empty. The average benchmark score is 0, which indicates that no performance data points have been recorded for this processor in the database. The sole quantitative performance indicator is the percentileVsAllCpus value of 50, placing this SoC exactly at the median of the entire CPU population tracked by the database. This median position suggests that, despite being a low-power mobile part, it is not at the bottom of the performance distribution—yet the absence of recorded scores means the 50th percentile is an unverified statistical placeholder rather than a measured result.
Without nearest rival data, direct percentage deltas against competitors cannot be computed. However, the clock specifications offer a performance envelope. The base clock of 1.80 GHz and boost clock of 2.70 GHz show a substantial uplift from base to boost, implying that workloads capable of triggering boost will experience a meaningful increase in execution speed. The 2.70 GHz boost clock is the highest frequency available, and the gap between base and boost is notable for a 6W part. Because no benchmark scores exist, the practical impact of this clock behavior on real-world applications is not quantified, leaving the 50th percentile as the only comparative metric.
Platform and Compatibility
The A9-9420e uses the AMD Socket FT4, a mobile-oriented socket. It supports DDR4 memory with a single-channel memory bus, providing a memory bandwidth of 17.1 GB/s. ECC memory is not supported, which limits its use in error-correcting environments. For expansion, the SoC provides PCIe Gen 3 with 8 lanes, but these are CPU-only lanes, meaning the integrated graphics and other on-die components share this limited connectivity. The integrated graphics are the Radeon R5 with 3 compute units, which is the sole GPU solution on this SoC.
The multiplier is locked (multiplierUnlocked: false), so overclocking is not possible. The part number is AM942EANN23AC. The production status is end-of-life, which means the platform is no longer actively manufactured or supported for new designs. This end-of-life status restricts the upgrade path—users cannot move to a newer processor on the same socket, as AMD Socket FT4 is not a forward-looking platform. The memory support is limited to DDR4, and the single-channel bus constrains memory bandwidth to 17.1 GB/s, which is a significant limitation for memory-intensive applications. The 8 PCIe Gen 3 lanes are adequate for basic peripherals but insufficient for high-bandwidth add-in cards.
How It Compares
The nearestRivals field in the fact pack is empty, meaning the database provides no direct competitor names, scores, or deltaPct values for this SoC. Consequently, a rival-by-rival comparison cannot be performed using the available data. The only positional metric is the percentileVsAllCpus value of 50, which places the A9-9420e at the median of all CPUs in the database. This suggests that, in the absence of measured scores, the processor is considered average relative to the entire field. The average benchmark score of 0 further complicates any comparative analysis, as it indicates no recorded performance data points to validate the percentile placement. Without rival scores, performance deltas cannot be expressed as percentages, and the A9-9420e's standing must be interpreted solely through its median percentile rank.

Who Should Consider It
For gaming workloads, the A9-9420e is a poor fit. The 2 cores and 2 threads provide minimal multi-threading capability, and the Radeon R5 with 3 compute units is a low-end integrated graphics solution. The 50th percentile rank does not translate into gaming performance, as no benchmark scores are available to confirm frame rates. For content creation, the 2-thread ceiling severely limits multi-threaded rendering, encoding, and compilation tasks. The boost clock of 2.70 GHz helps with lightly threaded creation tasks, but the lack of additional threads will bottleneck any parallel workload.
For office and basic productivity, the A9-9420e is acceptable for light-duty tasks such as word processing, spreadsheet work, and web browsing. The low TDP of 6W and mobile market segment make it suitable for ultra-portable laptops and fanless designs. The 17.1 GB/s memory bandwidth is adequate for these workloads, and the 2.70 GHz boost clock provides responsive single-threaded performance for everyday applications. However, the end-of-life status means it is only relevant for legacy systems or replacement parts. Users with demanding multi-threaded workloads should avoid this SoC, while those needing a low-power, basic computing device may find it sufficient.
Single-Thread vs Multi-Thread Behavior
The A9-9420e has 2 cores and 2 threads, indicating that simultaneous multithreading is not supported. The base clock is 1.80 GHz, and the boost clock is 2.70 GHz. The boost clock is significantly higher than the base clock, suggesting that single-threaded workloads which trigger boost will see a substantial performance uplift. In multi-threaded scenarios, the processor can only utilize 2 threads, so scaling is strictly limited to that count. The absence of benchmark scores means the exact single-thread versus multi-thread performance split is not quantified, but the clock behavior implies a strong single-thread capability.
For real workloads, this means that applications with a single primary thread—such as legacy office suites or light web browsing—will benefit from the 2.70 GHz boost clock. Conversely, applications that are heavily multi-threaded, such as modern video encoders or 3D renderers, will be constrained by the 2-thread ceiling. The 1.80 GHz base clock is the sustained frequency under multi-threaded load, which is notably lower than the boost. This split indicates that the A9-9420e is designed for bursty, single-threaded tasks rather than sustained parallel processing. The 6W TDP further reinforces this design, as higher multi-threaded frequencies would generate more heat than the thermal envelope allows.
Power and Thermals
The A9-9420e has a TDP of 6W, which is extremely low. This implies minimal thermal output, allowing for passive cooling solutions or very small active fans. The processor is built on a 28 nm process node by GlobalFoundries, with 1,200 million transistors on a 125 mm² die. The combination of a 6W TDP and a 28 nm process means the power density is low, but the 1,200 million transistors on a 125 mm² die indicate a relatively dense layout for its era. The low TDP is the primary consideration for cooling design—any standard mobile cooling solution, including a thin heat pipe or a small fan, is more than sufficient.
The end-of-life status does not alter the thermal profile, but the 6W TDP class is a defining characteristic. This power envelope enables fanless operation in ultra-thin notebooks and tablets, which aligns with the mobile market segment. The boost clock of 2.70 GHz, while higher than the base 1.80 GHz, is still achievable within the 6W TDP, indicating that the power management is tightly controlled. For system integrators, the thermal design is straightforward: a passive cooler or a low-profile active cooler will handle the heat output. The lack of an unlocked multiplier means no overclocking headroom, so thermals will remain within the designed envelope under all operating conditions.
