AMD Athlon XP-M 2500+ (72W)

The AMD Athlon XP-M 2500+ (72W) is a single-core mobile processor from the K7 architecture, built on the Barton codename with a 130 nm process node. It operates at a base clock of 1867.00 MHz, integrates 128 KB of L1 cache and 512 KB of L2 cache, and carries a 72W TDP. Released on 2003-03-11, this part is now end-of-life and targets the mobile segment via AMD Socket A.

Benchmark Performance

The FACT PACK lists no benchmark scores for this processor, and the average benchmark score is 0. The percentile versus all CPUs is 50, which places it exactly at the midpoint of the database distribution — a neutral position, neither a standout nor an outlier. Without direct scores, the performance analysis must rely on architectural context: the Barton core with 512 KB L2 cache was designed for balanced throughput in its era, but the single core and single thread configuration limits its ceiling in modern multi-threaded workloads.

The nearestRivals array is empty, meaning no direct comparative deltas are available. This absence is itself informative: the benchmark database does not currently hold a comparable processor with a measured score, so any relative performance claim would be speculative. The 50th percentile suggests that if a score were computed, it would sit at the median of all recorded CPUs — but with a zero average score, the data indicates no valid benchmark run has been submitted for this part. Users should treat any external performance expectation as unverified against this database.

Given the lack of rival deltas, the only quantitative statement possible is the percentile position. A 50th percentile ranking implies that half of all CPUs in the database are faster and half are slower, but this is a statistical artifact of the empty benchmark field rather than a measured outcome. The absence of scores means the page cannot confirm or refute performance claims from other sources.

Who Should Consider It

The Athlon XP-M 2500+ (72W) is a mobile processor, so its intended audience is laptop or compact desktop users from its 2003 era. For gaming, the single core at 1867.00 MHz can handle titles from that period, but modern games with multi-threaded requirements will not benefit — the data shows only one thread available. Creation workloads like video encoding or 3D rendering rely heavily on multi-core scaling, and with a single core, these tasks would be severely limited. Office productivity, such as word processing or spreadsheet work, is feasible given the 512 KB L2 cache, which helps with repeated data access, but the lack of memory support details in the FACT PACK leaves memory bandwidth unquantified.

The market segment field explicitly labels this as "Mobile," so it suits portable systems where the 72W TDP is a moderate power envelope for its generation. The multiplier is unlocked, which allows overclocking — a feature that could extend its useful life for enthusiasts willing to push the base clock beyond 1867.00 MHz. However, without memory support data, the platform’s full capability cannot be assessed. The integrated graphics note says "On certain motherboards (Chipset feature)," meaning visual output depends on the chipset, not the CPU — so a discrete GPU is likely required for any graphical workload.

Single-Thread vs Multi-Thread Behavior

The processor has 1 core and 1 thread, so there is no multi-threaded execution at all — every workload runs on a single logical path. The base clock of 1867.00 MHz is the only clock figure available, with no boost clock listed, meaning the processor runs at a fixed frequency under load. Single-thread performance is the sole metric that matters here; the 512 KB L2 cache helps reduce memory latency for sequential tasks, but the L1 cache at 128 KB is modest by modern standards.

In real workloads, this split is stark: any application that can use multiple threads will see zero scaling, because there is only one thread to schedule. Single-threaded tasks, such as legacy productivity software or older games, will perform according to the 1867.00 MHz clock and the cache hierarchy. The absence of a boost clock suggests no dynamic frequency adjustment, so sustained performance equals the base clock — no temporary speed bursts. For modern operating systems that background services across threads, this processor would quickly become a bottleneck, as the single thread must handle the OS overhead plus the foreground application.

FAQ

Q: What is the base clock speed of this processor?

A: The base clock is 1867.00 MHz, with no boost clock listed in the FACT PACK.

Q: How many cores and threads does it have?

A: It has 1 core and 1 thread, so it can process only a single instruction stream at a time.

Q: Is the multiplier unlocked for overclocking?

A: Yes, the multiplierUnlocked field is true, which allows the user to adjust the multiplier (and thus the clock speed) beyond the default 1867.00 MHz.

Q: What is the TDP and what does it imply for cooling?

A: The TDP is 72W. This is a moderate power envelope for a mobile processor of its era, suggesting it requires a heatsink and fan adequate for 72W of heat dissipation, but not an exotic cooling solution.

Q: Does it have integrated graphics?

A: The FACT PACK states integrated graphics are "On certain motherboards (Chipset feature)," meaning the CPU itself does not include a GPU; the motherboard chipset may provide video output, but this is not guaranteed.

Q: What socket does it use?

A: It uses AMD Socket A, which was common for the Athlon XP generation.

Power and Thermals

The 72W TDP classifies this processor as a moderate-power mobile part. For its release in 2003, a 72W envelope was typical for a high-performance mobile chip, requiring a capable cooling solution but not a full desktop tower cooler. The 130 nm process node is relatively large by modern standards, which influences heat density; the die size is 101 mm², and the transistor count is 63 million. These figures suggest a chip that can be cooled by a standard notebook heatpipe or a small desktop heatsink, but not passively — the 72W must be dissipated actively.

The absence of a boost clock means the processor does not vary its frequency under thermal pressure; it runs at a fixed 1867.00 MHz, so thermal management is straightforward — the cooling solution must handle 72W continuously. For overclocking (multiplier unlocked), the thermal requirement rises above 72W, demanding a better cooler than the stock solution. The data does not specify a maximum temperature, so the safe thermal limit is unknown, but the TDP gives a clear baseline for cooling design.

Platform and Compatibility

The processor uses AMD Socket A, a PGA socket that was widely used in the early 2000s. Memory support is not listed in the FACT PACK, so the type (DDR, SDRAM) and channel configuration cannot be stated. PCIe support is also absent from the data, which is expected for a 2003-era part — Socket A platforms typically used AGP for graphics and PCI for peripherals, but those details are not in the pack. The ECC memory field is false, meaning the processor does not support error-correcting memory.

The integrated graphics note ("On certain motherboards (Chipset feature)") indicates that video output depends on the motherboard’s chipset, not the CPU. The multiplierUnlocked field is true, providing overclocking flexibility. The production status is end-of-life, so no new units are manufactured, and the upgrade path is limited to other Socket A processors from the same generation, though no specific compatible models are listed in the FACT PACK. The part number is AXMA2500FKT4C, which can be used for identification. The release date of 2003-03-11 places it in the Barton era, and the architecture is K7, codename Barton.

How It Compares

The nearestRivals array is empty, so there are no direct rival comparisons available from the FACT PACK. This absence means the database has not recorded any processor with a measured benchmark score that falls within a comparable range for this part. Without rival names, scores, or deltaPct values, any comparison to other CPUs would violate the rule to use only the given data. Therefore, the position is undefined relative to specific competitors.

The percentileVsAllCpus of 50 offers a general reference: it sits at the median of all CPUs in the database. However, this percentile is based on the zero average benchmark score, which is not a real measurement. In the absence of rival data, the only honest statement is that no comparative analysis can be performed from the FACT PACK. Users seeking a competitive ranking must look elsewhere, as this database entry lacks the necessary benchmark records to establish relative performance.
