AMD E2-3800

The AMD E2-3800 is a 4-core, 4-thread mobile processor built on the 28 nm Jaguar architecture (codename Kabini) for the AMD Socket FT3 platform. It operates at a fixed base clock of 1300 MHz, integrates Radeon HD 8280 graphics, and is positioned in the low-power mobile segment with a 15 W TDP.

Benchmark Performance

The benchmark data for the E2-3800 shows an average benchmark score of 0, which places it at the 50th percentile among all CPUs in the database. This percentile ranking indicates that the processor sits exactly in the middle of the distribution when considering all tracked processors, but the zero score itself suggests that it does not generate a meaningful performance metric in the current benchmark suite. The absence of nearest rivals in the data means there are no direct percentage deltas to cite for comparison; however, the 50th percentile is a critical reference point. Practically, this implies that half of all CPUs in the database score at or below this level, which for a 2014-era mobile part is consistent with a low-power design focused on basic productivity and media consumption rather than computational throughput. The lack of any boost clock means the 1300 MHz base is the maximum sustained frequency, so the processor cannot temporarily elevate performance under light loads. In multi-core workloads that scale across all four cores, the E2-3800 will rely entirely on its modest clock speed and small shared L2 cache, the data shows 2 MB of shared L2, to complete tasks, which will result in scores that are far below modern desktop or even higher-end mobile parts. Users should interpret the 50th percentile as a midpoint marker, not an indicator of competitive strength; it reflects the broad mix of all CPUs, including many that are significantly more powerful.

Single-Thread vs Multi-Thread Behavior

The E2-3800 has 4 cores and 4 threads, meaning there is no simultaneous multithreading, each core handles exactly one thread. This configuration is symmetric for single-thread and multi-thread workloads in terms of core count, but the lack of a boost clock is the defining factor. Single-thread performance is capped by the 1300 MHz base clock, and because there is no turbo range, the processor cannot increase frequency when only one or two cores are active. This makes single-thread responsiveness, such as opening applications, scrolling web pages, or running older software that is not well-parallelized, dependent on the Jaguar architecture’s efficiency at that fixed clock. The 64 KB L1 cache per core helps reduce latency for frequently accessed data, but the small size and low clock will limit performance in any latency-sensitive task. Multi-threaded workloads, such as video encoding or compiling, can use all four cores, but the 2 MB shared L2 cache and single-channel memory bus (with 12.8 GB/s bandwidth) will become bottlenecks. The data indicates that memory bandwidth is shared across all cores, so when all four threads are active, cache misses will force accesses to DDR3 memory through a single channel, reducing effective throughput. For real-world use, the E2-3800 behaves like a processor that handles light multi-tasking (e.g., a few browser tabs, office documents) adequately but will struggle with sustained multi-threaded compute. The absence of a boost clock means there is no transient performance advantage; the processor runs at the same pace regardless of load, which at least provides predictable behavior.

Power and Thermals

The E2-3800 has a TDP of 15 watts, which classifies it as an ultra-low-power mobile processor. This TDP figure is the thermal design power, meaning the cooling solution must dissipate at least 15 watts under sustained loads. For a 28 nm process from GlobalFoundries, this TDP is very modest, and the processor does not require an active cooling fan in many chassis designs, a passive heat spreader or a small low-profile cooler is typically sufficient. The die size is 107 mm², which is relatively small, and with four cores at 1300 MHz, the power density is low. The integrated Radeon HD 8280 graphics shares the same die and TDP budget, so under combined CPU and GPU load, the total heat output stays within the 15 W envelope. For builders selecting a cooling solution, the data implies that any capable air cooler designed for low-TDP mobile sockets will be more than adequate; there is no need for liquid cooling or high-end air towers. The end-of-life production status means that replacement parts are not being manufactured, so thermal management should also consider the age of the unit, thermal paste may have degraded. The 15 W TDP also suggests that this processor is intended for fanless or near-silent designs, such as thin laptops or compact embedded systems. From a practical standpoint, the thermal envelope is so low that overheating is unlikely unless the cooling solution is completely blocked or the ambient temperature is extreme.

How It Compares

The FACT PACK provides no nearest rivals for the E2-3800, so a direct comparison with specific competitor models is not possible from the given data. The only reference point is the 50th percentile across all CPUs, which serves as a generic marker. In the absence of rival scores and delta percentages, the assessment must rely on architectural characteristics. Compared to processors with higher base clocks or boost capabilities, the E2-3800 will lose decisively in every throughput metric because it cannot raise its frequency. Against other low-power 4-core parts from the same era, the Jaguar architecture’s efficiency is its main asset, the 15 W TDP allows it to fit into power-constrained designs where higher-TDP parts cannot operate. However, the single-channel memory bus at 12.8 GB/s is half the bandwidth of many dual-channel contemporaries, which will penalize memory-intensive workloads. The integrated Radeon HD 8280 provides basic graphics capability, but without benchmark data, its performance relative to other iGPUs is unknown. For users considering this processor today, the lack of nearest rivals in the database suggests it is not commonly benchmarked, and its 50th percentile position is likely skewed by the inclusion of many much older and slower parts. In essence, the E2-3800 is a functional, low-power processor that will handle everyday tasks but offers no performance headroom for demanding applications.

FAQ

Q: What is the base clock speed of the AMD E2-3800?

A: No, the production status is end-of-life, and it was released on January 4, 2014.

Platform and Compatibility

The E2-3800 is built for the AMD Socket FT3, which is a BGA (ball-grid array) socket, meaning it is soldered to the motherboard and not user-replaceable. The platform is based on the Kabini codename and uses the Jaguar architecture, which is a low-power design aimed at mobile and embedded systems. Memory support is DDR3, but the memory bus is single-channel, with a maximum bandwidth of 12.8 GB/s. This is a significant limitation for memory-intensive applications, as dual-channel platforms would offer double the bandwidth. The processor supports ECC memory, which is unusual for a consumer mobile part, and may appeal to specific industrial or server-like use cases. For PCIe, the E2-3800 provides Gen 2 with 8 lanes from the CPU only, which is sufficient for a single discrete GPU or a few NVMe drives, though the lack of Gen 3 support will reduce peak transfer rates compared to newer platforms. The integrated graphics are Radeon HD 8280, which shares the system memory for video output; there is no dedicated VRAM. The upgrade path is essentially nonexistent because the FT3 socket is soldered and end-of-life; users cannot swap the processor for a higher-performing model without replacing the entire motherboard. The part number is EM3800IBJ44HM, and the processor is not multiplier-unlocked, so overclocking is not possible. For a new build, this platform is only viable if the user already owns a compatible motherboard or is sourcing used components. The 28 nm process node and GlobalFoundries foundry are old by current standards, but the low TDP of 15 watts makes it suitable for fanless designs where power efficiency is the priority over performance.
