Intel Pentium III 1400S

The Intel Pentium III 1400S is a single-core, single-thread desktop processor built on the P6 architecture with the Tualatin codename. It operates at a base clock of 1400 MHz, integrates 512 KB of L2 cache and 8 KB of L1 cache, and is manufactured on a 130 nm process with 44 million transistors on an 80 mm² die. Released in 2002 for Intel Socket 370, this end-of-life part carries a 32 W TDP and sits at the 50th percentile in the database's overall CPU ranking. The processor is not multiplier unlocked, and it does not support ECC memory. Integrated graphics are available only as a chipset feature on certain motherboards, not on the processor itself.

Benchmark Performance

The database lists no individual benchmark scores for this processor; the average benchmark score is recorded as 0. Consequently, the only quantitative performance indicator available is the percentile ranking against all CPUs, which stands at 50. This places the Pentium III 1400S exactly at the median of the tracked processor population. Without direct scores, the data cannot substantiate a specific performance delta against any other part. The absence of benchmark entries means that any claims about raw speed must be inferred from its clock, cache, and architecture rather than from measured results. The 1400 MHz base clock and 512 KB L2 cache suggest a design aimed at responsive single-threaded operation, but the database's percentile is the sole numeric anchor for its standing. A median percentile typically indicates that half of the database's CPUs are ranked above it and half below, though the lack of a benchmark score leaves the exact basis of this ranking undefined. The part number SL5XLSL657SL6BYSL6JP is the only identifying code provided, confirming the processor's presence in the database without any measured performance record.

Single-Thread vs Multi-Thread Behavior

This processor is strictly single-threaded, with one core and one thread. There is no boost clock listed, so the 1400 MHz base clock is the only operating frequency. The P6 architecture and Tualatin codename indicate a mature design focused on instruction efficiency rather than parallel throughput. Real-world implications are clear: workloads that rely on a single execution stream will see the full benefit of the 1400 MHz clock, while any multi-threaded application will not scale beyond the single thread. The 512 KB L2 cache is substantial for the era, helping to feed the single core with data. For office productivity, legacy software, or lightweight single-tasking environments, the single-thread behavior is adequate. For modern multitasking or heavily threaded creation workloads, the lack of additional cores or threads is a fundamental limitation. The processor's single-thread focus means that performance is directly tied to the clock speed and cache efficiency, with no parallel execution to compensate for slower clocks. The 8 KB L1 cache is small by modern standards, but the 512 KB L2 cache provides a meaningful buffer for the single execution core.

Power and Thermals

The TDP is rated at 32 W, placing this processor in a low-power class. This figure, combined with the 130 nm process node, implies modest thermal output. A basic air cooler or a simple heatsink with a small fan is sufficient to manage the heat generated by a 32 W part. The die size of 80 mm² and 44 million transistors further indicate a compact, efficient design. The low TDP also makes it suitable for systems where power delivery and cooling are constrained, such as small form factor or legacy tower cases. The data does not provide specific thermal measurements, but the 32 W rating strongly suggests that cooling is not a challenging requirement. The processor is end-of-life, so modern cooling solutions are not a concern, but any standard Socket 370 cooler will comfortably handle the thermal load. The 130 nm process is relatively large by modern standards, yet the 32 W TDP keeps thermal management simple and inexpensive. The processor does not support ECC memory, which is a consideration for users needing error-correcting memory in legacy servers or workstations.

How It Compares

The database lists no nearest rivals for the Intel Pentium III 1400S. Therefore, a direct comparison against specific named competitors is not possible from the available data. The 50th percentile ranking is the only comparative metric. This median position indicates that, among all CPUs tracked in the database, it sits in the middle of the pack. However, because the average benchmark score is 0, the percentile may reflect the processor's inclusion in the database rather than a measured performance level. Without rival scores or delta percentages, any assertion of being faster or slower than a particular part would be unsupported. The processor's single-core design and 1400 MHz clock place it in a legacy performance tier, but the lack of rival data prevents a precise positioning. The end-of-life status and 2002 release date further contextualize it as a historical part, not a current contender. The production status of end-of-life confirms that it is no longer manufactured, and the market segment is Desktop, clarifying its intended use case.

Who Should Consider It

Given its single-core, single-thread design and 32 W TDP, this processor is best suited for basic office tasks, legacy software, and lightweight single-tasking environments. The 1400 MHz clock and 512 KB L2 cache provide enough responsiveness for word processing, spreadsheet work, and simple web browsing on older operating systems. For gaming, the single-thread nature and lack of modern instruction sets make it unsuitable for contemporary titles, but it could handle early 2000s games. For content creation, the absence of multi-threading is a severe bottleneck; video editing or rendering workloads would perform poorly. The 50th percentile ranking suggests it is a mid-tier part in the database's historical context, but the lack of benchmark scores means it should be evaluated on its specifications alone. Enthusiasts building a retro system or maintaining legacy hardware will find it a functional, low-power choice. However, for any modern workload requiring parallelism, this processor is not recommended. The end-of-life status and 2002 release date further reinforce its role as a legacy component. The 32 W TDP makes it an easy fit for passive or near-passive cooling setups in vintage builds, though the data does not specify such configurations.
