Intel Pentium 4 1.6

The Intel Pentium 4 1.6 is a single-core desktop processor from the NetBurst architecture, built on the Willamette core. It operates at a fixed 1600.00 MHz with no boost clock, and the database places it at the 50th percentile among all CPUs, though its average benchmark score is recorded as 0, indicating a lack of aggregated performance measurements. This analysis relies solely on the architectural facts and positional data available, with no rival scores to reference.

Benchmark Performance

The FACT PACK contains no individual benchmark scores, and the nearestRivals array is empty, so no direct percentage deltas can be cited. The only quantitative performance markers are the 1600.00 MHz base clock and the 50th percentile ranking. A percentile of 50 places this processor at the exact median of the database's historical CPU population, meaning it is neither a standout nor a laggard in that context. However, the average benchmark score of 0 suggests that no empirical tests have been recorded for this unit, so the percentile may reflect its architectural classification rather than measured results. The lack of a boost clock means the processor cannot exceed its rated frequency under any condition, making the 1600.00 MHz the absolute ceiling. The cache hierarchy—an 8 KB L1 and a 256 KB L2—is the only other performance-relevant data. Without rival scores, the benchmark behavior must be inferred: the 256 KB L2 is modest, and the 180 nm process with 42 million transistors defines a structural baseline, but no performance validation exists to confirm real-world throughput.

Platform and Compatibility

The processor uses the Intel Socket 478 interface, a platform specific to the NetBurst generation. Memory support is listed as both DDR1 and DDR2, which is notable for a single processor, implying a transitional design that can work with motherboards from either memory era. The integrated graphics are described as a chipset feature on certain motherboards, meaning the CPU itself contains no graphics core; any display output depends entirely on the board's chipset. No PCIe specification is listed, leaving the expansion bus undefined. The multiplier is locked, so overclocking via multiplier changes is impossible. The processor is end-of-life, with a release date of 2001-08-26, and its part number string (SL5UWSL5USSL5UJSL6BCSL679SL5VH) indicates multiple steppings. ECC memory is not supported, and no memory bus width or bandwidth figures are provided. The die size is 217 mm², with 42 million transistors on a 180 nm process. The upgrade path is constrained by the socket and the end-of-life status, but the dual memory support hints at compatibility with a range of motherboards from that era.

Single-Thread vs Multi-Thread Behavior

With exactly 1 core and 1 thread, this processor is strictly serial. The base clock of 1600.00 MHz is the only frequency, and the absence of a boost clock means no dynamic frequency scaling. The L1 cache is 8 KB, and the L2 is 256 KB. The NetBurst architecture is known for deep pipelines that favor high clock speeds, but a 1600 MHz clock is modest, so performance relies heavily on cache efficiency. The 256 KB L2 is small for a desktop processor, potentially causing frequent cache misses in workloads that exceed that capacity. The lack of multi-threading means parallel workloads gain nothing from additional logical processors. For single-threaded applications, the processor's behavior is predictable: constant frequency, no turbo, and a fixed cache size. The 50th percentile ranking suggests a mid-tier historical position, but with no benchmark scores, the real-world split between single-thread and multi-thread performance cannot be quantified. The data implies that any workload is bound by the single thread, and the small cache will limit performance in data-intensive tasks.

Who Should Consider It

The 50th percentile ranking places this processor at the median of the database's historical population, but the zero average benchmark score means there is no measured performance to validate any recommendation. For gaming, the lack of integrated graphics (relying on a chipset feature) forces a discrete GPU, and the single core with a 256 KB L2 would likely bottleneck modern titles. For content creation, the single thread and small cache would hinder rendering or encoding, which typically benefit from multiple cores. For office applications, the 1 core and 1 thread limit multitasking, but simple word processing or spreadsheet tasks might run adequately at 1600 MHz. The processor supports DDR1 and DDR2 memory, both of which are outdated. The end-of-life status and 2001-08-26 release date place it firmly in the early 2000s, making it a legacy component. The data suggests it is best suited for retro systems or educational use, not as a primary daily driver. The 50th percentile indicates it is not a performance outlier, but the lack of scores leaves its practical capability undefined.

Power and Thermals

The thermal design power (TDP) is 61 watts, a fixed value from the FACT PACK. For a single-core processor on a 180 nm process, 61 W indicates a moderate power draw. The die size is 217 mm², and the transistor count is 42 million. The 180 nm process is large by modern standards, which typically leads to higher power consumption per transistor, but the 61 W figure is the only thermal data point. The lack of a boost clock means power draw is constant under load, with no dynamic frequency changes. A TDP of 61 W implies that a standard air cooler designed for socket 478 would be sufficient; the data does not specify a cooling tier, but the wattage is within the range of typical air-cooled desktop processors. No thermal throttling information is provided, so sustained performance under heavy load is unknown. The processor is end-of-life, so cooling solutions are legacy, but the 61 W TDP is the key number for any cooling selection.

How It Compares

The nearestRivals array in the FACT PACK is empty, so there are no rival names, scores, or deltaPct values to reference. The only positional data is the percentileVsAllCpus of 50, which places this processor at the exact median of all CPUs in the database. Without rival data, a comparative analysis cannot be performed, and no percentage deltas can be cited. The average benchmark score of 0 further indicates a lack of measured performance, so any comparison would be purely architectural. The processor's 1600 MHz clock and 256 KB L2 are the only performance-relevant specs, but they cannot be contrasted with any competitor. The absence of rivals means that this page cannot offer a delta percentage analysis, and the processor's standing remains defined solely by its median percentile and its structural facts—1 core, 1 thread, 61 W TDP, and socket 478. The data suggests a neutral historical position, but without measured scores, its relative performance is indeterminate.
