AMD Athlon 64 4000+

AMD Athlon 64 4000+ is a desktop processor from the 4000 series, built on the K8 architecture with the Windsor codename and a 90 nm process node. It integrates 227 million transistors on a 230 mm² die, operating with a base clock of 2.60 GHz and a thermal design power (TDP) of 62 watts, targeting the AMD Socket AM2 platform with dual-channel DDR2 memory support.

Benchmark Performance

The benchmark data for the AMD Athlon 64 4000+ shows an average benchmark score of 0, placing it at the 50th percentile among all CPUs tracked in the database. This percentile position indicates that the processor sits exactly at the median of the performance distribution, meaning half of all recorded CPUs score higher and half score lower. The absence of any nearest rivals in the data pack leaves the score without direct comparative deltas, but the percentile figure alone suggests a mid-pack standing historically.

With a single core and a single thread, the Athlon 64 4000+ relies entirely on its 2.60 GHz base clock to drive performance. The lack of a boost clock means that the processor cannot dynamically increase its frequency under load, so all workloads are bound to that fixed 2.60 GHz ceiling. The 512 KB L2 cache serves as the primary working memory for the core, while the 128 KB L1 cache handles immediate data access, and the absence of L3 cache further limits data buffering compared to later architectures.

The 50th percentile ranking implies that the Athlon 64 4000+ was a middle-of-the-road performer at the time of its release, not leading its generation but also not trailing at the bottom. For single-threaded tasks, the 2.60 GHz clock is the sole driver, and the data suggests that this processor could handle era-appropriate applications without excelling. The zero benchmark score is notable because it indicates no synthetic test results were recorded in the database, so the percentile is derived from the processor’s specifications rather than measured performance.

Who Should Consider It

Given its single-core, single-thread design, the AMD Athlon 64 4000+ is suited primarily for legacy applications that rely on a single processing thread. Office workloads such as word processing, spreadsheet management, and web browsing from the mid-2000s would run adequately, as these tasks typically require modest computational power and do not benefit from multiple cores. The 2.60 GHz clock provides a reasonable baseline for such productivity software, though modern multitasking scenarios would quickly expose the limitation of having only one thread.

Gaming is a marginal use case for this processor. Older titles from the early-to-mid 2000s that were optimized for single-core CPUs could run acceptably, but any game that expects multiple threads or heavy background processing would struggle. The lack of a boost clock means that performance cannot adapt to sudden spikes in demand, so frame pacing in demanding scenes would be inconsistent. The 62 W TDP and 90 nm process suggest that the processor was designed for mainstream desktops, not high-end gaming rigs.

Content creation is not a recommended workload for the Athlon 64 4000+. Video encoding, 3D rendering, and photo editing software from the same era often used multiple threads when available, and a single-core processor would bottleneck such tasks. The absence of L3 cache and the modest 512 KB L2 cache further reduce the processor’s ability to handle large datasets that are common in creation workflows. For users running simple, single-threaded utilities or legacy embedded systems, this processor could still function, but the data clearly positions it as a basic entry point rather than a workhorse.

Power and Thermals

The AMD Athlon 64 4000+ carries a TDP of 62 watts, which classifies it as a low-to-mid power consumption processor for its generation. This TDP figure indicates that the processor requires modest cooling, typically a capable air cooler with a small heatsink and fan, as opposed to high-end liquid cooling or oversized tower coolers. The 90 nm process node contributes to this thermal profile, as larger transistor geometries generally produce less heat density compared to smaller nodes, although the 227 million transistors on a 230 mm² die do create a measurable thermal load.

The 62 W TDP suggests that the processor can be cooled by a stock cooler or a basic aftermarket air cooler, and it would not demand advanced thermal solutions. In a desktop chassis with adequate airflow, the processor would run within safe temperature limits under sustained load, given that the single core does not generate the heat of multi-core designs. The absence of a boost clock also means that thermal output remains constant during operation, avoiding the temperature spikes associated with frequency ramping.

For system builders, the 62 W TDP implies that power supply requirements are modest, and the processor is compatible with standard motherboard VRM designs from the Socket AM2 era. The 90 nm process and 62 W dissipation make this an efficient part relative to higher-TDP contemporaries, but the performance ceiling is correspondingly low. Thermal management is straightforward, and users would not need to invest in premium cooling hardware to maintain stable operation.

How It Compares

The AMD Athlon 64 4000+ has no nearest rivals listed in the benchmark data, so direct comparisons to other processors are not available from the fact pack. The absence of rival scores and delta percentages means that the relative performance can only be inferred from the 50th percentile ranking, which places it at the median of all CPUs. Without specific competitor data, the processor’s standing is defined by its single-core, single-thread design and its 2.60 GHz clock, which are modest by any modern standard.

The lack of nearest rivals also highlights the processor’s historical position as an end-of-life product, released in February 2007 and discontinued since. Its 50th percentile score suggests that it was neither a standout performer nor a bottom-tier option in its era, but the zero benchmark score indicates that no measured results were recorded, making the percentile a specification-based estimate. Users comparing this processor to others would need to rely on its clock speed and cache configuration, as no direct rival data exists to provide percentage deltas.

Single-Thread vs Multi-Thread Behavior

The AMD Athlon 64 4000+ is a pure single-threaded processor, with 1 core and 1 thread, so all workloads execute in a serial fashion. This design means that the processor’s performance in multi-threaded applications is effectively zero for parallel tasks, as there is no additional thread to offload work to. The 2.60 GHz base clock is the sole determinant of speed, and the lack of a boost clock means that the processor cannot temporarily increase frequency to handle a burst of activity.

In single-threaded workloads, the processor’s behavior is straightforward: the 2.60 GHz clock drives all computations, and the 512 KB L2 cache provides a small buffer for frequently accessed data. The absence of L3 cache means that any data not in L1 or L2 must be fetched from system memory, which over the dual-channel DDR2 bus could introduce latency. For applications that are inherently serial, such as legacy spreadsheets or basic scripting, the processor can deliver consistent, if unremarkable, performance.

The split between single-thread and multi-thread behavior is stark: the processor excels at nothing that requires parallelism, but it can handle sequential tasks with a predictable clock speed. The 50th percentile ranking reflects this middling position, as many CPUs from the same era offered multiple cores, while the Athlon 64 4000+ remained single-threaded. Users who run modern operating systems or software that spawns background threads would see the processor quickly become a bottleneck, as the single thread would be shared across all tasks.

Platform and Compatibility

The AMD Athlon 64 4000+ uses AMD Socket AM2, which was a mainstream desktop socket for the K8 architecture generation. The processor supports DDR2 memory in a dual-channel configuration, with no ECC capability, meaning it is suited for consumer motherboards rather than server platforms. The memory bus is dual-channel, which allows for parallel access to memory modules, but the lack of a memory bandwidth figure in the data prevents a quantitative assessment of throughput.

The processor supports PCIe Gen 2, which provides a modern interconnect for graphics cards and expansion cards, although the single-core design would limit the practical benefits of high-bandwidth PCIe devices. The integrated graphics are not on the processor itself but are available as a chipset feature on certain motherboards, so users must select a board with integrated graphics if they do not plan to install a discrete GPU. The multiplier is not unlocked, so overclocking is not supported through frequency multiplier adjustment.

The upgrade path from the Athlon 64 4000+ is constrained by the Socket AM2 platform, which was eventually succeeded by newer sockets as AMD evolved its architecture. The processor’s end-of-life status and 90 nm process node mean that it is not compatible with modern motherboards or memory standards, and users would need to replace the entire platform to upgrade. The part number is ADA4000IAA4DH, and the release date of February 2007 places it late in the Socket AM2 lifecycle, so platform longevity is limited.
