No benchmark data available for this CPU.
About AMD Sempron 3400+
The AMD Sempron 3400+ is a single-core mobile processor from the K8 architecture generation, released in mid-2006 with a 2000 MHz base clock. Its benchmark data is empty, which places it at the 50th percentile of all CPUs in the database, indicating a median position that tells only part of the story.
Benchmark Performance
The benchmark results for the AMD Sempron 3400+ are notably absent from the dataset, with an average benchmark score of 0.0 and no recorded workload scores. This absence is itself a data point: the processor's performance profile cannot be quantified through the standard suite, suggesting either extremely limited testing coverage or a performance level too low for meaningful comparison in modern benchmarks. The percentile ranking of 50 places it exactly at the median of all CPUs in the database, which is a statistical anomaly given the lack of actual scores — this likely reflects the processor's historical position rather than any measured contemporary performance.
What can be inferred comes from the architecture and clock specifications. The single core running at 2000 MHz represents the entry point of the K8 mobile lineup, designed for basic productivity tasks in an era when dual-core processors were becoming mainstream. Without rival scores or delta percentages in the nearestRivals field, the data provides no direct comparative percentages. The 50th percentile suggests that in the broader historical context of all processors ever benchmarked, this chip sits exactly in the middle — but this is a rank without a score, making it more an artifact of database classification than a meaningful performance metric.
The empty benchmarks field means no multi-threaded or single-threaded scores exist to analyze. For a processor with one core and one thread, the absence of data is particularly telling — modern benchmark suites often struggle to run or produce meaningful results on such limited hardware. The 90 nm process node and 69 million transistors indicate the physical design, but these manufacturing details do not translate into performance figures without actual test results.
How It Compares
The nearestRivals array is empty, meaning the database contains no direct comparative processors with scores and delta percentages for this chip. This lack of rival data is significant — it suggests the Sempron 3400+ occupies a niche so specific or so outdated that the database does not track comparable parts in its current benchmark framework. Without deltaPct values, no percentage-based comparisons can be made, and no rival names are available for reference.
This absence of rivals could imply that the processor's performance class is either too low for the database's minimum threshold or that historical mobile processors from this era are simply not represented. The single-core, single-thread design from 2006 places it in a category that has been entirely superseded, and the database's comparative framework may not accommodate such legacy parts. The 50th percentile rank, therefore, stands alone without contextual validation from peer processors.
For users examining this data, the key takeaway is that the Sempron 3400+ cannot be positioned relative to any competing chip using the available metrics. The empty rival list is a statement in itself: this processor has no meaningful peers in the current benchmarking landscape.
Power and Thermals
The thermal design power (TDP) for the AMD Sempron 3400+ is 25 watts, a figure that places it in the ultra-low-power class for its 2006 release period. This 25 W TDP indicates the processor was engineered for thin-and-light mobile systems where battery life and heat dissipation were primary concerns. The K8 architecture at 90 nm with 69 million transistors running at 2000 MHz achieves this modest power envelope through conservative clock speeds and a single-core design.
A 25 W TDP implies a cooling solution of minimal complexity — a small passive heatsink or a low-speed fan is sufficient to manage thermals. This is a significant advantage for mobile chassis design, allowing for thinner profiles and quieter operation compared to higher-TDP parts. The data shows no boost clock, meaning the processor runs at a fixed 2000 MHz regardless of thermal headroom, which simplifies thermal management but also means no performance scaling under load.
The power characteristics suggest this processor belongs in the "capable air cooler" tier, where even basic cooling implementations handle the heat output without issue. The 25 W figure is notably low even for the era, competing with ultra-low-voltage parts in efficiency. However, the lack of boost capability means the thermal solution is not tested by dynamic frequency changes — the processor's thermal output is constant and predictable.

Who Should Consider It
Given the benchmark scores are empty, recommendations must be grounded in the architectural specifications. The single-core, single-thread design at 2000 MHz with 256 KB of L2 cache and 128 KB of L1 cache indicates this processor is suited only for the most basic computing tasks. Office work involving word processing, spreadsheet navigation, and email would run acceptably, provided the software is lightweight and the operating system is from the same era. Modern office suites with heavy background processes would likely strain the single thread.
Gaming is not a realistic use case for this processor. The single core cannot handle modern game engines, and the lack of integrated graphics on the processor itself — relying on chipset features — further limits any graphical capability. Even games from the 2006 era would run at low settings and resolutions, and the data provides no benchmark scores to suggest otherwise.
Content creation workloads such as video editing, 3D rendering, or photo manipulation are entirely out of scope. These tasks require multi-threaded performance, and the Sempron 3400+ has only one thread available. The 256 KB L2 cache would become a bottleneck for any data-intensive creative application. The processor is best considered for legacy systems, basic point-of-sale terminals, or embedded applications where the 25 W TDP and 90 nm process are acceptable trade-offs for the fixed 2000 MHz clock.
Single-Thread vs Multi-Thread Behavior
The Sempron 3400+ is a pure single-thread processor with 1 core and 1 thread, so there is no multi-thread behavior to analyze. The distinction between single-thread and multi-thread performance is moot — every workload runs on the same single execution path. The 2000 MHz clock speed determines all performance, and the 256 KB L2 cache provides a small buffer for frequently accessed data.
This design means that single-thread performance is the only metric that matters, and it is directly tied to the clock speed and architecture efficiency. The K8 architecture was known for strong single-thread performance in its era, but without benchmark scores, the data cannot quantify this. The absence of a boost clock means the processor cannot temporarily increase frequency for demanding single-thread tasks, so performance is constant.
In real-world terms, the single-thread nature means the processor handles one task at a time with no multitasking ability. Background processes will directly compete with foreground applications for the same execution resources. The 128 KB L1 cache and 256 KB L2 cache are small by modern standards, limiting the amount of data that can be held close to the execution core. For users, this means the processor is adequate for sequential, low-complexity tasks but will struggle with anything that requires simultaneous processing or large data sets.
Platform and Compatibility
The AMD Sempron 3400+ uses AMD Socket 754, a platform from the K8 architecture era. The memory support is single-channel with no ECC capability, and the memory bus width is single-channel as well. The data shows no memory bandwidth figure, but the single-channel configuration inherently limits memory throughput compared to dual-channel platforms. The processor does not support PCIe with no version or lane count listed, which significantly restricts modern expansion options.
The integrated graphics are provided "On certain motherboards (Chipset feature)," meaning the processor itself has no graphics core. This places the graphics burden entirely on the motherboard chipset, which limits display output options to what the specific motherboard provides. The 90 nm process node and 69 million transistors are fixed characteristics of the design, and the production status is end-of-life, meaning no new units are being manufactured.
The upgrade path from this processor is extremely limited. Socket 754 is a legacy socket with no modern processor releases, so users are confined to other Socket 754 processors from the same era. The single-channel memory support and lack of PCIe further constrain the platform's longevity. The processor was released in 2006 for the mobile segment, and its part number is SMS3400BQX3LE. The memory bus is single-channel, and ECC memory is not supported, which limits its use in error-sensitive environments. For anyone considering this processor today, the platform compatibility is the primary concern — it requires period-specific motherboards, RAM, and potentially proprietary mobile components that are no longer in production.
