AMD A8-3800

The AMD A8-3800 is a 32 nm desktop processor from the K10 family, built under the Llano codename by GlobalFoundries. It pairs four CPU cores with an integrated Radeon HD 6550D GPU on Socket FM1, with dual-channel DDR3 memory support and a 65 W TDP. The FACT PACK contains no benchmark scores and no nearest rivals, so this analysis is based on the specification fields rather than measured performance.

FAQ

Q: What socket does the AMD A8-3800 use?

A: The processor is designed for AMD Socket FM1. It is a desktop part, and its production status is listed as end-of-life.

Q: What is the core and thread configuration?

A: It has 4 cores and 4 threads, meaning it presents four logical processors to the operating system. There is no L3 cache listed; each core has 128 KB of L1 cache and 1 MB of L2 cache.

Q: What are the clock speeds?

A: The base clock is 2.40 GHz and the boost clock is 2.70 GHz. The multiplier is not unlocked, so the chip is not intended for easy multiplier-based overclocking.

Q: Does it include integrated graphics?

A: Yes, it includes a Radeon HD 6550D integrated GPU. The memory interface is dual-channel DDR3 with 29.9 GB/s of memory bandwidth.

Q: What process node and foundry are listed?

A: The process node is 32 nm and the foundry is GlobalFoundries. The die contains 1,178 million transistors on a 228 mm² die.

Q: Does it support ECC memory?

A: No. The ECC memory field is false, so ECC memory support is not part of the specification.

Who Should Consider It

Because the benchmark arrays are empty, the recommendation is necessarily specification-driven rather than score-driven. Desktop builders on Socket FM1 who want integrated graphics are the most direct audience: the Radeon HD 6550D provides a GPU inside the processor, eliminating the need for a separate graphics card in systems that only require display output. The four cores and four threads give it a straightforward symmetric setup for workloads that can use four concurrent threads.

The 2.40 GHz base clock and 2.70 GHz boost clock indicate a modest operating range. Office and productivity tasks that do not demand extreme single-thread burst performance can be handled by this clock profile, especially when the workload distributes across all four cores. The 65 W TDP class also suggests that the processor fits into systems with relatively simple cooling requirements. For creation workloads, the data does not include score evidence, so a confident creation-oriented verdict is not possible from this FACT PACK. What can be said is that the processor has four threads, no L3 cache, and 29.9 GB/s of dual-channel DDR3 bandwidth; the architecture relies on per-core L1 and L2 caches rather than a large shared cache.

Users already committed to the FM1 platform, DDR3 memory, and PCIe Gen 2 are the natural candidates. The absence of an unlocked multiplier means users who plan heavy overclocking should look elsewhere. The integrated Radeon HD 6550D, dual-channel memory controller, and desktop segment classification all point to a mainstream all-in-one APU-style part rather than a high-end enthusiast CPU. For workloads that require more than four threads, the 4-core/4-thread configuration is a limiting factor. For workloads that fit within four threads and an integrated GPU, the A8-3800 is a coherent match.

Power and Thermals

The TDP is 65 W, which places the A8-3800 in a modest power envelope. The 32 nm process from GlobalFoundries contributes to this class of power draw, though the FACT PACK does not include any specific thermal measurements. A 65 W TDP implies that a capable air cooler can handle the heat output; there is no data in the pack that would require liquid cooling or an oversized thermal solution. The integrated GPU and CPU share the same package, so the 65 W figure covers the combined part as listed. Since the production status is end-of-life, thermal guidance is historical rather than current. The absence of an L3 cache and the presence of four cores with 1 MB L2 per core mean the thermal design is focused on a moderate, mainstream desktop footprint.

Architecture and Design

The A8-3800 uses the K10 architecture under the codename Llano, and the generation is identified as A8 (Llano). The die is manufactured on a 32 nm process at GlobalFoundries and contains 1,178 million transistors across a 228 mm² die. The core layout is simple: 4 cores and 4 threads, with no SMT-style extra thread count. Each core carries 128 KB of L1 cache and 1 MB of L2 cache, while the L3 cache field is null. This is a per-core cache hierarchy rather than a pooled L3 design.

The memory controller supports DDR3 in dual-channel mode, with a listed memory bandwidth of 29.9 GB/s. ECC memory is not supported. The PCIe interface is Gen 2. The integrated graphics is a Radeon HD 6550D, and the processor is built for the AMD Socket FM1 platform. The multiplier is not unlocked, and the market segment is Desktop. The release date is 2011-06-29, and the production status is end-of-life. The part number in the FACT PACK is AD3800OJZ43GXAD3800OJGXBOX. Taken together, the design is a 32 nm Llano-era APU with a notable integrated GPU, a four-thread CPU, and a dual-channel DDR3 memory path.

Benchmark Performance

The FACT PACK lists an empty benchmarks array, an average benchmark score of 0, and a percentile versus all CPUs of 50. This is not a typical measured benchmark profile; it is a data-field state that indicates no performance samples are present. The only comparative signal is the 50th-percentile rank, which places the A8-3800 at the median of the CPU distribution in this database. However, because the average benchmark score is 0, that median rank should be interpreted with caution: there are no actual score numbers behind it.

No nearest rivals are listed, and therefore no deltaPct values exist. This means the data cannot support statements such as “30% faster than” any processor. The benchmark performance section of this page is, in effect, an absent dataset rather than a measured result. What can be inferred from adjacent fields is limited to the CPU clock profile and cache/memory characteristics. A four-core, four-thread processor with a 2.40 GHz base and 2.70 GHz boost clock would typically be positioned in the low-to-mid desktop range, but the FACT PACK does not provide the score evidence needed to make that statement as a benchmark conclusion.

Single-Thread vs Multi-Thread Behavior

The A8-3800 has 4 physical cores and 4 threads, so each core is responsible for one thread. This is a symmetric design with no extra logical threads per core. The boost clock of 2.70 GHz is 0.30 GHz above the base clock of 2.40 GHz, giving a modest amount of single-thread headroom when the workload requires it. Because there is no L3 cache, the cache hierarchy is per-core: 128 KB of L1 and 1 MB of L2 per core. A workload that is highly single-threaded will depend on the 2.70 GHz boost clock and the per-core cache. A workload that spreads across all four threads can use all four cores simultaneously, though the lack of additional threads means there is no oversubscription benefit from SMT.

The FACT PACK does not include separate single-thread or multi-thread benchmark scores. Therefore, the exact ratio between single-thread and multi-thread performance cannot be quantified. The structural data suggests a balanced design: four threads, per-core L2, and a modest boost range. Applications that rely on a single core will see the 2.70 GHz ceiling, while multi-threaded applications can engage all four cores up to the same per-core clock. The memory bandwidth of 29.9 GB/s over dual-channel DDR3 is shared by the CPU and the integrated Radeon HD 6550D, so memory-heavy multi-thread workloads may be affected by bandwidth contention. Again, this is a design-level observation, not a measured benchmark result.

How It Compares

The nearestRivals field in the FACT PACK is empty. There are no rival names, no rival scores, and no deltaPct values to analyze. Because of this, no direct comparison to a specific alternative CPU can be made from the data provided. The only positional metric is percentileVsAllCpus, which is 50. That places the A8-3800 in the middle of the database’s CPU ranking, but with an average benchmark score of 0, the percentile is not supported by underlying benchmark data.

Without nearest rivals, this section cannot provide the usual one-paragraph-per-rival breakdown. There is no basis to compare against any named processor, whether older or newer, or to state a percentage advantage or deficit. The FACT PACK simply does not include the comparison data. Readers should treat the A8-3800 as a part whose architectural and specification fields are documented, but whose measured competitive position is undetermined by this dataset.
