Intel Core Duo LV L2400

The Intel Core Duo LV L2400 is a 65 nm mobile processor from the Core Duo (Yonah) generation, released in early 2006 and now end-of-life. It operates within a 15 W TDP envelope, features two cores and two threads, and runs at a base clock of 1666.00 MHz. The processor's benchmark data shows a 50th percentile ranking among all CPUs, indicating it sits near the median of the performance distribution; however, its average benchmark score is zero, and the database lists no nearest rivals, meaning its performance cannot be directly quantified against other parts in this dataset.

Benchmark Performance

The Intel Core Duo LV L2400 presents a unique challenge for performance analysis: the FACT PACK lists no benchmark scores, no nearest rivals, and an average benchmark score of zero. This absence of quantitative data means the processor's raw performance cannot be expressed as a precise score or a percentage delta relative to other CPUs. The 50th percentile ranking, while placing it at the midpoint of all CPUs, is not accompanied by any reference points to establish what that percentile means in absolute terms. Without rival scores or deltaPct values, any statement about its speed relative to another processor would be unsupported.

Interpreting the zero average benchmark score requires caution. It could indicate that no validated benchmarks have been submitted for this unit, or that the processor was not tested in the standardized suite used by the database. The 50th percentile position, therefore, is a structural placement rather than a derived performance metric. In practical terms, the L2400's two cores and two threads at 1666.00 MHz suggest it was designed for a low-power mobile segment, but the data does not allow for a numerical comparison against, for example, a higher-clocked desktop chip or a later-generation part. The processor's production status is end-of-life, which may explain the lack of active benchmark submissions in the current database.

Single-Thread vs Multi-Thread Behavior

The L2400 has two cores and two threads, meaning it offers no simultaneous multithreading; each core handles exactly one thread. This configuration is characteristic of the early Core Duo architecture, which prioritized power efficiency over parallel throughput. The base clock of 1666.00 MHz applies to both cores, and there is no boost clock listed, so the processor operates at a fixed frequency under load. For single-threaded workloads, the L2400 relies entirely on its architectural efficiency and clock speed, but without benchmark scores, the data cannot quantify how it performs against a rival with a higher clock.

Multi-threaded behavior is similarly constrained by the 2-thread limit. Applications that can utilize exactly two threads will see both cores engaged, but workloads requiring more than two threads will experience queueing. The L2400's L2 cache is 2 MB, shared between the two cores, which can help reduce latency for data shared across threads. However, the absence of an L3 cache (null in the data) means all caching is localized to the 2 MB L2. The memory support is limited to DDR1, which may bottleneck data transfer in multi-threaded scenarios that require frequent memory access. The data indicates the processor does not support ECC memory, so it targets consumer or standard mobile use rather than error-correcting environments.

Power and Thermals

The L2400 carries a TDP of 15 W, placing it in the low-power mobile class. This figure is the only thermal or power metric in the FACT PACK; there are no cooling recommendations, measured temperatures, or wattage figures for rivals. A 15 W TDP implies that a modest cooling solution, such as a small fan or a passive heatsink in a well-ventilated chassis, would be sufficient. The architecture is built on a 65 nm process node, manufactured by Intel, which is relatively large by modern standards but was efficient for its time.

The low TDP is consistent with the processor's "LV" designation, which typically denotes low voltage. This positioning suggests the L2400 was intended for thin-and-light laptops or embedded systems where heat dissipation and battery life take priority over peak performance. The integrated graphics are listed as "On certain motherboards (Chipset feature)," meaning graphics capability is not built into the CPU die but depends on the chipset of the motherboard. This setup keeps the CPU's thermal output lower than a part with integrated graphics on-die. The 15 W TDP also aligns with the 65 nm process and the 151 million transistor count; the die size is 90 mm², which is compact and contributes to lower power draw.

How It Compares

Since the nearestRivals field is empty, the L2400 cannot be positioned against any specific competitor in the database. There are no names, scores, or deltaPct values to reference. This absence is notable: it means that within the current dataset, no other processor has been clustered near the L2400 based on benchmark performance. The 50th percentile ranking is a global placement, not a relative one. Without rival data, any comparison would require speculation, which is outside the scope of this analysis.

The market segment is explicitly "Mobile," and the socket is Intel Socket 479, which was used in several portable systems of that era. The release date of 2006-01-04 places it in the early dual-core mobile era. The processor's part numbers (SL8VWSL9JT) indicate at least two stepping variants, but no performance differentiation is recorded. The lack of rivals could stem from the processor's niche status as a low-voltage part, which may not have been widely benchmarked in the same conditions as mainstream mobile or desktop CPUs. The data simply does not support a comparative narrative.

Who Should Consider It

The L2400 is a processor that the data positions as a low-power mobile solution, but with no benchmark scores, recommendations must be grounded in its architectural specifications rather than measured performance. Gamers should not consider this part: the two cores and 1666.00 MHz base clock, combined with DDR1 memory support, are insufficient for modern gaming workloads, which typically require higher clock speeds and more threads. The lack of a boost clock means no headroom for bursty gaming tasks. The integrated graphics are chipset-dependent and not on-die, further limiting gaming viability.

For content creation, the L2400 is equally unsuitable. Video editing, 3D rendering, and large-scale compilation benefit from multiple cores and high memory bandwidth; the L2400's 2-thread limit and DDR1 support would create significant bottlenecks. The 2 MB L2 cache may help with small datasets, but the absence of an L3 cache reduces efficiency for larger working sets. The 15 W TDP does not translate into computational throughput; it simply means the processor stays cool.

Office and productivity workloads present the most plausible use case. Basic word processing, spreadsheet tasks, web browsing, and email are typically single-threaded or lightly threaded, and the L2400's two cores can handle these sequential tasks at 1666.00 MHz. The 50th percentile ranking suggests it is not an outlier in either direction, so for a legacy office machine running lightweight software, the L2400 could suffice. However, the end-of-life status and DDR1 memory limitation mean users would be restricted to older software and operating systems. The data does not indicate any scenario where the L2400 excels; it is a functional but unremarkable mobile processor from an early dual-core era, best suited for basic, low-power tasks where thermal efficiency is prioritized over performance.
