AMD Athlon 64 3800+ (F3)

The AMD Athlon 64 3800+ (F3) is a single-core desktop processor from AMD’s 3000 series, built on the K8 architecture with the Orleans codename. Released in early 2007, it targets the Socket AM2 platform, features a 2.40 GHz base clock, and carries a 59 W TDP, making it a modest entry-point chip for its generation.

Benchmark Performance

The FACT PACK lists no direct benchmark scores for the AMD Athlon 64 3800+ (F3), with an average benchmark score of 0 and an empty benchmarks array. Its percentileVsAllCpus stands at 50, meaning the processor sits exactly at the median of all CPUs in the database — neither a standout performer nor a laggard. This percentile is a relative ranking, not an absolute score, so it indicates that half of all tracked processors score higher and half score lower.

Because the nearestRivals array is empty, there are no direct rival comparisons with specific deltaPct values to cite. The data provides no exact percentage deltas against any competitor. However, the 50th percentile placement is informative: it suggests that in aggregate, the Athlon 64 3800+ (F3) delivers mid-pack performance among all CPUs tracked by the database. For a single-core, single-thread part from 2007, this median position likely reflects its age and limited parallel capability relative to multi-core contemporaries, but the FACT PACK does not supply explicit rival scores to quantify that gap.

The absence of benchmark data means quantitative performance analysis must rely on architectural context. The processor has 1 core and 1 thread, which inherently limits its multi-tasking throughput compared to multi-core designs. Its 2.40 GHz base clock is the sole frequency figure, with no boost clock available, so performance is fixed at that speed under all loads. The 90 nm process node and 154 million transistors suggest a mature, power-conscious design, but these figures do not translate into specific performance numbers without benchmark results.

Single-Thread vs Multi-Thread Behavior

The Athlon 64 3800+ (F3) is a strictly single-threaded processor: 1 core and 1 thread mean it can execute only one instruction stream at a time. This is a critical distinction for workload analysis. Single-thread performance is the only kind it offers, so any task that cannot be parallelized will run at the full 2.40 GHz speed, but tasks that benefit from multiple threads will see no scaling whatsoever.

In real-world terms, the data shows that this chip is optimized for sequential workloads. A 2.40 GHz clock on a single K8 core can handle basic office productivity, web browsing, and light document editing without issues, as these tasks are predominantly single-threaded. However, modern applications that rely on multi-threading — such as video encoding, 3D rendering, or heavy spreadsheet calculations with parallel formulas — will bottleneck severely because the processor cannot distribute work across cores.

The cache hierarchy supports this single-thread focus: 128 KB of L1 and 512 KB of L2 cache are allocated to the one core, providing a reasonable amount of fast access memory for a single execution stream. The dual-channel DDR2 memory support (with a 128-bit memory bus) helps feed that core, but the lack of L3 cache means all data must come from L2 or system memory, which can increase latency in cache-miss-heavy workloads. The 50th percentile ranking likely reflects that this processor handles single-thread tasks adequately but offers no headroom for parallel workloads, a typical profile for early-to-mid-2000s desktop chips.

Who Should Consider It

Given its single-core design and 59 W TDP, the Athlon 64 3800+ (F3) is best suited for specific, low-demand scenarios. The data indicates it is end-of-life, so it is not a current purchase recommendation, but for legacy systems or retro builds, it has a clear niche.

For office and productivity work — word processing, spreadsheet entry, email, and web browsing — the single 2.40 GHz core is sufficient. These tasks are largely sequential and do not require high thread counts, so the processor will deliver predictable, if not fast, performance. The 50th percentile ranking suggests it is not embarrassingly slow for such workloads, merely average.

For light gaming, the Athlon 64 3800+ (F3) can handle older titles that are single-threaded by design, particularly those from its 2007 era. Games from that period typically used one or two threads, so a single-core chip with a decent clock speed can produce playable frame rates. However, the processor lacks integrated graphics — the FACT PACK notes graphics are "On certain motherboards (Chipset feature)" — so a discrete GPU is mandatory, which limits its appeal for integrated builds.

For creation workloads like video editing, 3D modeling, or audio production, this processor is not recommended. These applications are heavily multi-threaded, and the 1-core/1-thread configuration will cause severe slowdowns. The data shows no boost clock, so there is no temporary speed increase to help with bursty tasks; performance is flat at 2.40 GHz. Users with such needs should look to multi-core alternatives, though the FACT PACK provides no rival data to name specific chips.

For home theater PCs (HTPCs) running media playback, the Athlon 64 3800+ (F3) could suffice for standard-definition or early high-definition video, as playback is often single-threaded and the 2.40 GHz clock is adequate. The 59 W TDP is low enough for passive or small-form-factor cooling, but the lack of integrated graphics means a low-power discrete GPU is needed, increasing system complexity.

How It Compares

The nearestRivals array in the FACT PACK is empty, so there are no specific rival names, scores, or deltaPct values to reference. Consequently, direct quantitative comparisons cannot be made. The percentileVsAllCpus of 50 is the only comparative metric available, placing the processor at the exact midpoint of the database’s CPU distribution.

Without rival data, the comparison must be qualitative. Against contemporary multi-core processors (which would likely sit above the 50th percentile), the Athlon 64 3800+ (F3) will trail in any multi-threaded test due to its single core. Against older or lower-clocked single-core parts, its 2.40 GHz speed would give it an edge, but no specific deltaPct is provided to quantify that. The empty benchmarks array means there is no empirical score to measure against any competitor.

The processor’s position in the 3000 series and its Orleans architecture suggest it was a mid-range SKU at launch, but the FACT PACK does not include launch MSRP or market positioning details beyond the desktop segment. Its end-of-life status indicates it has been superseded, and any comparison to modern CPUs would be moot without benchmark numbers.

Power and Thermals

The TDP is 59 W, which places the Athlon 64 3800+ (F3) in a low-to-mid power class for its era. This figure is explicitly stated in the FACT PACK and represents the thermal design power — the maximum heat the cooling system must dissipate under sustained load. A 59 W TDP is modest by 2007 standards, where many desktop CPUs ranged from 65 W to 125 W.

This TDP implies a capable air cooler is sufficient. A stock cooler with a small aluminum heatsink and a 80mm or 92mm fan would handle the thermal load without issue, as 59 W is well within the range of basic cooling solutions. The 90 nm process node contributes to this efficiency — smaller transistors generally produce less heat per clock, and the 2.40 GHz clock is not extreme, so thermal density is manageable.

The lack of a boost clock means power draw is constant under load; there is no turbo mode that would spike TDP temporarily. This stability makes thermal management predictable. The processor’s die size of 103.1 mm² and 154 million transistors are relatively compact, which helps heat dissipation across the integrated heat spreader. For system builders, a low-profile cooler or even a passive cooler with adequate airflow might suffice, though the FACT PACK does not specify cooler requirements beyond the TDP figure.

The 59 W TDP also has implications for system power supply sizing. A 59 W CPU leaves ample headroom for a discrete GPU and other components, so a typical 300 W to 400 W power supply would be more than adequate. The processor supports dual-channel DDR2 memory, which has lower power consumption than later DDR3 or DDR4, further reducing overall system draw. No power efficiency ratings are provided, so the data cannot confirm exact wattage savings, but the TDP class is clear.

In summary, the Athlon 64 3800+ (F3) is a low-power, single-threaded desktop processor that sits at the 50th percentile of all CPUs. Its 59 W TDP makes it easy to cool, its 2.40 GHz clock handles single-thread tasks adequately, but its lack of multi-core capability and absent benchmark scores limit its appeal to legacy or basic use cases.
