About AMD Athlon 64 3100+
The AMD Athlon 64 3100+ is a single-core desktop processor from the 3000 series, built on the K8 architecture (codenamed Lima) and released on April 20, 2008. The fact sheet records a 2000 MHz base clock with no boost capability, a 25W TDP, and a 50th-percentile standing among all CPUs, although its average benchmark score is zero and no nearest-rival data is provided. This places the part in an unusual position: the specifications are clearly defined, but the performance data is absent, leaving the analysis to rest on architecture, thermals, and platform fit.
How It Compares
The nearestRivals field is empty, so there are no rival names, scores, or deltaPct values to cite. The only comparative signal is percentileVsAllCpus, which is 50. That figure means the processor sits at the median of the database's CPU distribution — but with an average benchmark score of zero, this percentile is best understood as a placeholder rather than a measured performance ranking. In practical terms, the Athlon 64 3100+ is a 1-core, 1-thread K8 part at 2000 MHz, which places it at the entry level of the desktop landscape of its release era. Without rival data, no quantitative comparison to contemporaries is possible; the analysis must instead rely on the architectural facts: a 65nm process, 122 million transistors, a 77 mm² die, and 512 KB of L2 cache. The 50th percentile, taken at face value, suggests that half of all CPUs in the database are at or below this level — a plausible position for a low-power single-core part, though the zero score means the percentile is not backed by any recorded benchmark.
Power and Thermals
The TDP is 25W, which is a very low thermal design power. Combined with the 65nm process node, this implies a minimal cooling requirement. A small passive heatsink or a low-profile aluminum cooler would be sufficient; the data does not specify a cooler, but the 25W figure places this chip in the lowest thermal tier. The 122 million transistors and 77 mm² die size are modest, which further supports the low-power profile. The 2000 MHz clock, running on a single core, generates limited heat. For system builders, this means the thermal solution can be small and quiet — there is no need for a large tower cooler or high-airflow case. The 25W TDP also suggests that the power delivery circuitry on the motherboard can be minimal, though no power figures are provided beyond the TDP itself. The end-of-life production status means that thermal solutions designed for this socket are no longer being produced, but the low TDP makes it easy to cool with generic, widely available parts.
Platform and Compatibility
The processor uses AMD Socket AM2. Memory support is DDR2, running on a dual-channel bus. ECC memory is not supported. The PCIe interface is Gen 2. Integrated graphics are not on the CPU; instead, they are available on certain motherboards as a chipset feature — meaning a discrete or motherboard-integrated GPU is required for display output. The multiplier is locked, so overclocking via multiplier adjustment is not possible. The production status is end-of-life, and the release date is April 20, 2008. The part number is ADS3100IAR4DRE. The platform implications: AM2 is a mature socket that supports DDR2 memory, which is now legacy. The dual-channel memory bus is standard for the era. The PCIe Gen 2 support provides a reasonable bandwidth for add-in cards of the period. The lack of ECC memory support means this is not suited for error-correcting memory workloads. The locked multiplier limits tuning options, but the 2000 MHz base clock is fixed. The upgrade path within AM2 would involve other AM2 processors, though the data does not list any compatible alternatives; the end-of-life status means no new processors are being released for this socket.

Who Should Consider It
Given the specifications — 1 core, 1 thread, 2000 MHz, 512 KB L2, 25W TDP — this processor is not suited to modern gaming or content creation. The data shows no multi-threading capability, so any workload that scales across cores will be limited. The 50th percentile and zero benchmark score provide no evidence of competitive performance. However, the low 25W TDP makes it a candidate for lightweight, always-on systems: a simple file server, a print server, or a dedicated appliance running a single task. For basic office productivity — word processing, spreadsheets, email — a single core at 2000 MHz can handle these tasks, though the lack of measured benchmarks means the data does not confirm this. The 512 KB L2 cache and 128 KB L1 are small, but for period-appropriate software from the mid-2000s, they are adequate. The end-of-life status means this is a legacy part, likely to be found in older systems or as a replacement for a failed CPU on an AM2 motherboard. The 25W TDP is the standout feature: for anyone building a low-power, low-noise system, this processor's thermal profile is a strong fit.
Single-Thread vs Multi-Thread Behavior
This processor has 1 core and 1 thread. There is no simultaneous multi-threading, no extra cores, and no boost clock. Every workload is executed on a single thread at 2000 MHz. This means the processor's entire performance identity is single-threaded. Multi-threaded applications — modern games, video encoders, compilers — will not benefit from any parallel execution; they will either run on the one thread or be limited by the lack of additional cores. The single-thread performance is determined by the K8 architecture and the 2000 MHz clock. For real workloads, this favors tasks that are inherently sequential: text editing, basic scripting, single-tab web browsing, or running a single legacy application. The absence of a boost clock means there is no headroom for transient loads. The data shows a locked multiplier, so the 2000 MHz is fixed. In summary, this is a purely single-threaded part, and any workload that expects multi-thread scaling will be disappointed.
Benchmark Performance
The average benchmark score is 0, and the percentile versus all CPUs is 50. The nearestRivals array is empty, so there are no rival scores or deltaPct values to analyze. The zero score is likely a data artifact — indicating that no standardized benchmark has been recorded for this sample — rather than a literal performance measurement. The 50th percentile is the median of the database, but with no score backing it, the percentile cannot be interpreted as a measured result. What the data does provide: a 2000 MHz base clock, a 512 KB L2 cache, and a 128 KB L1 cache. These are the only performance-relevant figures. Without benchmark scores or rival comparisons, no percentage deltas can be computed. The analysis must therefore rest on the architecture: K8 at 65nm, 122 million transistors, 77 mm² die. The absence of data is itself a finding — it means this part has not been tested in the database, and any performance claims would be speculative. The 50th percentile is the sole positional marker, and it is unverified by any score.
