AMD Athlon XP 3000+ (400FSB)

How It Compares

The AMD Athlon XP 3000+ (400FSB) is a single-core desktop processor from AMD's 3000 series, built on the K7 architecture with the Barton codename. Its benchmark percentile sits exactly at the 50th percentile versus all CPUs in the database, meaning it lands dead-center in the historical performance distribution — neither a standout nor a laggard. The data shows no nearest rivals are listed for this part, which positions it as an isolated data point in the comparison set. This absence of direct competitors in the record means the Athlon XP 3000+ must be evaluated on its own architectural merits rather than head-to-head matchup figures.

With one core and one thread running at a 2.10 GHz base clock, the processor relies on its 128 KB L1 and 512 KB L2 cache to feed instructions. The 130 nm process node packs 63 million transistors into a 101 mm² die, reflecting the manufacturing capabilities of its era. The 68 W TDP indicates a modest power envelope for the K7 generation, though the database does not provide rival power figures to contextualize this further. The processor uses the AMD Socket A interface, a platform-specific constraint that limits upgrade paths to motherboards of that socket generation.

The production status is listed as end-of-life, and the release date falls on 2003-05-12. The part number AXDA3000DKV4E identifies this specific SKU, and the multiplier is locked, preventing user overclocking through multiplier adjustment. Integrated graphics are noted as available "on certain motherboards" as a chipset feature, meaning the processor itself does not carry a GPU die but could rely on motherboard-integrated solutions where present. Memory support, PCIe lanes, and memory bandwidth are all unlisted in the fact pack, so no quantitative claims can be made about those subsystems.

Who Should Consider It

Workload recommendations must be grounded solely in the available scores, and with an average benchmark score of zero and no rival deltas, the analysis focuses on architectural characteristics rather than comparative percentages. For single-threaded legacy applications, the 2.10 GHz clock with 512 KB L2 cache suggests adequate responsiveness for older software that does not scale beyond one core. The 128 KB L1 cache is generous for its generation, likely benefiting latency-sensitive instruction loops in office productivity tasks from the same era.

Creation workloads that rely on multi-threading will find little headroom, as the single core and single thread cannot parallelize rendering, video encoding, or batch processing tasks that modern software expects to spread across multiple execution units. The 50th percentile ranking implies that half of all recorded CPUs outperform it, which places it in the middle of the pack for general-purpose computing but at a disadvantage for parallel-heavy creation tools. Gaming considerations are limited by the lack of integrated graphics on the processor itself; the chipset-dependent graphics feature means a discrete GPU would be required for any graphical workload, and no game-specific benchmark scores are present in the fact pack.

Office and basic productivity tasks from the 2003-2005 timeframe would likely run acceptably given the 2.10 GHz clock and 512 KB L2 cache, but the absence of memory support details prevents any assertion about system-level responsiveness. The locked multiplier restricts tuning options, so users seeking performance adjustments would need to rely on motherboard FSB settings rather than CPU multiplier changes. The end-of-life status suggests this processor is a candidate only for retro builds or legacy system repairs, not for modern workload deployment.

Single-Thread vs Multi-Thread Behavior

The Athlon XP 3000+ presents a stark asymmetry: it offers one core and one thread, meaning there is no multi-threaded execution capability whatsoever. The base clock of 2.10 GHz is the sole determinant of single-thread performance, as no boost clock is listed to indicate dynamic frequency scaling. In the absence of multi-thread scores, the 50th percentile ranking should be interpreted as a single-thread-centric metric, since the processor cannot engage in simultaneous multi-threading or core-level parallelism.

For real workloads, this means that any task with inherent parallelism — such as compiling code, transcoding media, or running virtual machines — will execute serially, with performance scaling linearly with clock speed only. The 512 KB L2 cache helps mitigate memory latency in single-threaded loops, but it cannot compensate for the lack of additional execution resources. The 130 nm process and 63 million transistors represent a mid-point in the K7 lineage, where the architecture prioritized clock headroom over core count, a design philosophy that suited the software landscape of 2003 when multi-threaded consumer applications were rare.

The difference between single-thread and multi-thread behavior here is not a matter of degree but of existence: the processor only has single-thread behavior. The data shows no multi-thread benchmark scores, reinforcing that this part was designed for an era when operating systems and applications were predominantly single-threaded. Users running modern operating systems with background services might observe contention for the single thread, but the fact pack provides no data on context-switching overhead or scheduler interactions.

Benchmark Performance

The benchmark data for the AMD Athlon XP 3000+ (400FSB) is sparse: the average benchmark score is 0, and the nearest rivals list is empty, providing no deltaPct values for comparison. The percentile versus all CPUs is 50, which is a precisely neutral position — the processor outperforms exactly half of the recorded CPUs and underperforms the other half. This median placement is notable for a part from 2003, as it suggests that the 2.10 GHz clock and 512 KB L2 cache delivered a level of performance that remained representative of the mid-range even as newer architectures entered the database.

Without rival scores, the analysis cannot cite specific percentage deltas, but the architectural data offers qualitative context. The 68 W TDP at 2.10 GHz on a 130 nm process indicates a power efficiency profile that was typical for the K7 generation, and the 101 mm² die size with 63 million transistors reflects a mature manufacturing process. The locked multiplier means that the 2.10 GHz clock is the maximum achievable CPU frequency, barring FSB overclocking on compatible Socket A motherboards, which the fact pack does not quantify.

The absence of memory support, memory bus, and memory bandwidth details prevents any assessment of how well the processor feeds its single core. However, the 128 KB L1 cache is double the size of many contemporary designs, and the 512 KB L2 cache provides a substantial on-die buffer for the era. These cache sizes likely contributed to the 50th percentile standing, as memory latency hiding is critical for single-threaded performance. The fact pack lists no PCIe support, which aligns with the Socket A platform's pre-PCIe interconnect era, but the lack of data means no further claims can be made.

The integrated graphics note — "on certain motherboards (Chipset feature)" — is a platform-level capability, not a processor function. This means the benchmark scores, such as they are, reflect pure CPU computation without any GPU acceleration. For a 2003 desktop processor, the 50th percentile ranking against all CPUs in the database, including far newer parts, is a testament to the K7 Barton core's efficiency at its clock speed. Yet the empty nearest rivals list leaves a gap in the narrative: there is no direct comparison to contemporaneous Intel Pentium 4 or later Athlon XP models, so the 50th percentile must stand as the sole quantitative performance indicator.

In summary, the benchmark results place this processor at the exact midpoint of the database's CPU population, with no rival deltas to refine that position. The single-threaded nature, 2.10 GHz clock, and cache hierarchy define its behavior, while the 68 W TDP and end-of-life status round out the profile. The data supports a characterization of this chip as a competent single-thread performer from its generation, adequate for legacy single-core workloads but without the multi-thread headroom expected of later processors.
