Intel Pentium III 1133

The Intel Pentium III 1133 is a single-core desktop processor from Intel, built on the P6 architecture with the Tualatin codename. It runs at a fixed 1133 MHz base clock with no boost, has a TDP of 29 watts, and is manufactured on a 130 nm process with 44 million transistors and an 80 mm² die size. The processor includes 8 KB of L1 cache and 256 KB of L2 cache, uses the Intel Socket 370 interface, and was released on June 30, 2001, but is now end-of-life. In the benchmark database, it holds a 50th percentile ranking among all CPUs, though its average benchmark score is recorded as zero, indicating that no performance data is available for this unit.

Benchmark Performance

The data for the Pentium III 1133 is notably sparse: the average benchmark score is zero, and the percentile versus all CPUs is 50. This means the processor sits exactly at the median of the database, but without any concrete scores, that percentile cannot be interpreted as a meaningful performance indicator. The absence of benchmark results suggests that this processor is rarely tested, likely due to its age and end-of-life status. Consequently, any performance analysis must rely on the architectural specifications rather than measured outcomes.

The processor has a single core and a single thread, with a base clock of 1133 MHz and no boost capability. This fixed clock speed is the sole frequency at which the processor operates. The cache hierarchy comprises 8 KB of L1 cache and 256 KB of L2 cache. The L2 cache size is relatively generous for the era, which can help mitigate the lack of a larger cache. However, without benchmark data, it is impossible to quantify how this cache configuration translates into real-world performance.

The single-core design means that performance is entirely dependent on single-threaded execution. Multi-threaded workloads will see no benefit from additional cores, as there are none. The 1133 MHz clock is high for the P6 architecture, but again, without scores, we cannot state how it compares to other processors. The 50th percentile ranking does place it in the middle of the database, but that ranking is based on a score of zero, which is not a typical benchmark result. Therefore, the percentile should be treated as a placeholder rather than a reliable metric.

Given the lack of benchmark data, the processor's performance profile is defined by its clock speed and cache. The 1133 MHz clock and 256 KB L2 cache suggest a processor capable of handling single-threaded tasks that are not excessively demanding. It is not suitable for modern multi-core applications, which are the norm today. The processor's performance, if any, would be limited to simple, legacy software that does not require parallel processing.

Who Should Consider It

The Pentium III 1133 is an end-of-life product, so it is not recommended for new system builds. Its single-core, single-thread architecture limits it to tasks that do not require multi-threading. For users seeking to assemble a period-correct retro PC, this processor could be a candidate, as it represents a high-clock variant of the Pentium III line. The low TDP of 29 watts makes it suitable for small form factor systems or those with minimal cooling requirements, though the exact cooling solution cannot be specified from the data.

The processor does not have integrated graphics; the only graphics support is listed as "On certain motherboards (Chipset feature)." This means a discrete graphics card is necessary unless the motherboard provides a chipset-based solution. For basic office applications that are single-threaded, the processor might suffice, but there is no benchmark evidence to confirm this. The lack of ECC memory support (ECC memory is false) and the fact that it is not multiplier unlocked further limit its appeal for modern or advanced use cases.

Given its end-of-life status, the processor is not a practical choice for daily computing. It could be used in legacy systems that require specific software compatibility or in embedded applications where the fixed clock and low power draw are advantageous. However, the absence of performance data means that any workload recommendation must be based solely on the architectural limitations: single-core, single-thread, and a 1133 MHz clock.

Platform and Compatibility

The Pentium III 1133 uses the Intel Socket 370 interface, a socket that was common for Pentium III and Celeron processors of that generation. The memory support is not specified in the data, so the type, speed, and maximum capacity of RAM cannot be determined. Similarly, PCIe support is not listed, indicating that the processor may predate PCIe or rely on older expansion bus standards. The processor does not support ECC memory, which is a feature that some server or workstation platforms require.

Integrated graphics are not part of the processor itself; they are a chipset feature available on certain motherboards. This means the processor relies on a discrete GPU for display output unless the motherboard includes an integrated graphics solution. The processor is not multiplier unlocked, so overclocking via multiplier changes is not possible. The part number is listed as SL5GQSL5LTSL6C4SL6JK, which can be used for identification.

The upgrade path is effectively nonexistent because the processor is end-of-life. Socket 370 motherboards are no longer produced, and the processor itself is no longer manufactured. Users looking to upgrade would need to replace the entire platform, including the motherboard and memory, as the socket and memory standards are outdated.

How It Compares

The nearestRivals field in the data is empty, meaning no direct comparisons to other processors are provided. Without rival names, scores, or deltaPct values, it is impossible to position the Pentium III 1133 against any specific competitor. The only comparative metric available is the percentile of 50, which places it in the middle of the database, but this is based on a zero average score and is not a meaningful comparison.

The lack of benchmark data further complicates any comparative analysis. Even if rivals were listed, the absence of scores would prevent a quantitative comparison. The processor's specifications, such as the 1133 MHz clock and 256 KB L2 cache, are its defining characteristics, but they cannot be used to infer relative performance without reference points. In this context, the processor stands alone in the database, and any statement about its position relative to other CPUs would be speculative.

Power and Thermals

The thermal design power (TDP) of the Pentium III 1133 is 29 watts. This is a low TDP, indicating that the processor does not generate excessive heat. A basic air cooler is likely sufficient, though the data does not specify a recommended cooling tier. The low TDP also makes the processor suitable for systems with limited cooling capacity, such as compact cases or passively cooled designs, provided the ambient temperature is controlled.

The single-core design contributes to the low power consumption. With only one core operating at 1133 MHz, the electrical load is minimal. The 130 nm process node also helps reduce power draw compared to older, larger process nodes. However, the exact thermal output is not provided beyond the TDP figure. The processor's end-of-life status means that replacement cooling solutions may be difficult to find, but the low TDP means that generic coolers compatible with Socket 370 should work without issue.
