AMD Mobile Athlon 64 3400+

The AMD Mobile Athlon 64 3400+ is a single-core, single-thread mobile processor from the 3000 series. It uses the K8 architecture under the Clawhammer codename and is listed as part of the Mobile Athlon 64 (ClawHammer) generation. The CPU runs on AMD Socket 754, has a base clock of 2.20 GHz, and no boost clock in the data. Its cache is 128 KB L1 and 1 MB L2, with no L3. Memory support is DDR1 over a single-channel bus, and ECC memory is not supported. The TDP is 82 W. The production status is end-of-life. The database entry records no benchmark scores, an average benchmark score of 0, and a percentileVsAllCpus value of 50. The nearestRivals list is empty.

Single-Thread vs Multi-Thread Behavior

With 1 core and 1 thread, this processor has no parallel execution hardware. The multi-thread side of the comparison is therefore not a reduced-capability mode; it is absent. A workload that distributes work across multiple threads will still execute on that single thread. No simultaneous execution of multiple threads is possible. The data shows a base clock of 2.20 GHz and no boost clock, so the single frequency figure is the sole reference point. For single-threaded code, the entire 128 KB L1 and 1 MB L2 resources are available to the one execution context. There is no L3 cache listed, and the vCache3d field is also null, so there is no extra stacked cache layer in this record. The cache hierarchy ends at 1 MB L2.

This configuration favors workloads that can complete within one thread, such as older or lightly threaded applications. It does not favor compilation, rendering, or any workload that expects multiple cores. A background task and a foreground task would be competing for the same single thread rather than running on separate cores. The base clock of 2.20 GHz is the only clock frequency in the data, and with no boost clock there is no higher frequency state recorded. The single-thread vs multi-thread split in the data is fully one-sided. Real-world performance character will be dominated by single-thread execution, because there is no second thread to absorb any parallel work.

Power and Thermals

The TDP is 82 W. That thermal design point defines the cooling class: any system using this CPU must be able to handle an 82 W envelope. The physical data behind this TDP includes a 130 nm process, 106 million transistors, and a 193 mm² die size. The processor is in the mobile market segment, which places this 82 W envelope inside a portable chassis. A cooling solution for this part therefore needs to move heat away from a compact space, but the data does not list cooler dimensions, fan specifications, or chassis requirements.

The architecture is K8, and the generation is Mobile Athlon 64 (ClawHammer). The process node is 130 nm, the only manufacturing geometry in the record. The 106 million transistor count on a 193 mm² die provides context for the 82 W TDP: this is a transistor budget and die area that require active thermal management. The foundry field is null, so the silicon manufacturer is not identified in the data. No memory bandwidth figure is listed, and no PCIe data is listed, so those fields do not contribute to the thermal analysis. Memory support is DDR1 over a single-channel bus, and ECC is not supported, which means the platform does not carry the extra thermal overhead of ECC operation. The cooling tier implied by the data is the tier appropriate for an 82 W mobile chip.

Benchmark Performance

The benchmarks array is empty. The average benchmark score is 0. In the percentileVsAllCpus field, this CPU is placed at 50. A 50th percentile position is the midpoint of the database's all-CPU ranking. However, because there are no benchmark scores and no nearestRivals entries, this percentile cannot be connected to any measured workload result. The data provides no exact percentage deltas to any rival. There are no rival names, no rival scores, and no deltaPct values in the FACT PACK. Thus, a performance analysis based on measured scores is not possible from this record.

What remains is specification-level interpretation: a single thread at 2.20 GHz, with 128 KB L1, 1 MB L2, and DDR1 single-channel memory. These specifications define the shape of possible performance, but they do not replace benchmark data. The 0 average score is not a performance measurement; it is the absence of measurement. The 50th percentile is a positional flag, not a tested score. The empty benchmarks array and the empty nearestRivals array together mean there is no measured score against which this CPU's performance can be placed. No further numeric performance claims can be derived from the record.

Who Should Consider It

Given the production status is end-of-life, the realistic audience is someone maintaining an existing AMD Socket 754 mobile system. The CPU's single-core, single-thread design means it is best suited to applications that use one thread. Office-style document work that does not require parallel processing would fall into that category, but the database has no office benchmark to confirm a specific experience. Creation workloads that depend on multi-threading will see only one thread. Rendering and similar parallel tasks would queue work on that one thread rather than spread it across cores. Gaming is not benchmarked in this record.

The integrated graphics field is listed as "On certain motherboards (Chipset feature)", which means display output depends on the motherboard or chipset, not on the CPU itself. Anyone building or repairing a system should therefore pair this processor with a Socket 754 motherboard that provides the needed graphics. The memory path is DDR1 and single-channel, and ECC is not supported, so the platform memory configuration is fixed by those parameters. The mobile segment and end-of-life status together indicate that this is not a current platform. Users who need more than one thread should look elsewhere; the 1-core/1-thread design is a hard constraint.

How It Compares

The nearestRivals field is an empty array. There are no nearest rivals listed for this CPU. No rival names, no rival benchmark scores, and no deltaPct values are present. Consequently, there is no rival-by-rival comparison to construct from the FACT PACK. The only comparative position available is percentileVsAllCpus at 50. This places the CPU at the midpoint of all CPUs in the database, but because the benchmark array is empty and the average score is 0, that midpoint is a database metadata position rather than a measured competitive result. The empty nearestRivals array is itself a data point: the database has not assigned competitive relationships for this processor. In the absence of nearestRivals, no named CPU comparison can be made from the data. The comparison story is therefore simple: the database does not define a competitive set for the Mobile Athlon 64 3400+.
