Intel Pentium 4-M 1.70

Intel's Pentium 4-M 1.70 is a single-core mobile processor from the NetBurst generation, built on the 130 nm Northwood process. It runs at a fixed 1.70 GHz base clock, consumes 30W TDP, and supports DDR1 and DDR2 memory. The database records no benchmark scores for this part, and its percentile rank of 50 places it exactly at the midpoint of all CPUs, though this rank is based on an empty benchmark set. Its specifications point to a modest, power-efficient chip for its era.

Benchmark Performance

The fact pack lists an average benchmark score of 0 and no individual benchmark entries. This means no standardized performance measurements exist for the Pentium 4-M 1.70 in this database. The percentile rank of 50 is the only comparative figure available, but without actual scores it is an empty statistic. In practice, the processor's performance must be inferred from its architecture and clock speed. It has one core and one thread, so it cannot execute multiple instructions in parallel. The base clock of 1.70 GHz is fixed; there is no boost clock to temporarily increase frequency. This fixed operation simplifies power management but caps peak throughput. The L1 cache is a small 8 KB, while the L2 cache is 512 KB. These cache sizes are modest by modern standards, but they were typical for early 2000s mobile parts. Given the lack of benchmark data, any comparison to other processors is impossible. The percentile rank of 50 suggests it sits in the middle of the database's CPU performance distribution, but because the benchmark score is zero, this rank should not be taken as evidence of actual performance parity. In essence, the benchmark section of this entry is a placeholder; the processor's real-world behavior would need to be measured separately.

The absence of a boost clock means the processor operates at a constant 1.70 GHz, which simplifies power budgeting and thermal design. For single-threaded workloads, the effective speed is directly tied to this fixed clock, and the small caches may limit performance in tasks that repeatedly access large datasets. The processor's NetBurst architecture, known for high clock speeds in desktop variants, is here constrained to a modest frequency. Without benchmark data, the percentile rank of 50 is the only numeric indicator, and it offers no meaningful insight because it is derived from an empty benchmark set. Users seeking performance comparisons must look elsewhere; this entry provides no scores to analyze.

Power and Thermals

The Pentium 4-M 1.70 is classified as a mobile processor, and its thermal design power (TDP) is 30 watts. This is a low TDP figure, especially for a NetBurst chip, which was known for high power consumption in desktop counterparts. The 30W rating indicates that the processor is designed to operate within a tight thermal envelope, suitable for laptops where cooling space is limited. The manufacturing process is 130 nm, which is relatively large by today's standards but was a leading-edge process in 2002. The die contains 55 million transistors and measures 131 mm². The combination of a low TDP and a modest transistor count suggests that the processor can be cooled by a simple heat sink and fan, or possibly a heat pipe, without requiring active liquid cooling. Because the processor has no boost clock, its power draw remains relatively constant under load, which simplifies thermal management. The mobile segment designation implies that the chip was optimized for battery life, though the database does not specify any power-saving features beyond the low TDP. In practice, a 30W TDP means the processor can be placed in a compact chassis, and the thermal solution does not need to handle sudden spikes in power consumption.

The 130 nm process node and 55 million transistor count are concrete indicators of the chip's physical footprint. A 131 mm² die is small enough to fit in a laptop motherboard without excessive heat generation. The lack of a boost clock further stabilizes power consumption, as there are no frequency jumps that would cause thermal transients. For system designers, the 30W TDP allows for a passive cooling solution in some low-profile devices, though the database does not confirm any specific cooling requirements. The processor's end-of-life status means that no new thermal guidance is forthcoming, but the given TDP is sufficient for basic thermal planning.

Platform and Compatibility

The Pentium 4-M 1.70 uses the Intel Socket 478 interface. This socket was common for Pentium 4 desktop and mobile processors in the early 2000s. The processor supports both DDR1 and DDR2 memory, giving system builders flexibility in choosing memory modules, though the database does not specify memory bus width or speed. ECC memory is not supported, which limits its use in error-correcting environments. The integrated graphics are not part of the processor itself; instead, they are "on certain motherboards (Chipset feature)". This means that the visual output depends on the chipset's integrated graphics controller, not on the CPU. The processor has no PCIe support listed in the database, so it is unclear whether it supports PCIe lanes; likely it uses an older bus like AGP or PCI, but that is not specified. The processor is marked as end-of-life, indicating that Intel no longer produces it. The release date is March 3, 2002. Since it is a mobile part, it is likely soldered or socketed in laptops, but the database does not specify. The part number is SL5Z7. The multiplier is not unlocked, so overclocking is not possible. The processor is a single-core, single-thread part, so it cannot take advantage of multi-threading. For upgrade paths, the socket 478 interface allows for replacement with other socket 478 processors, but no specific compatible models are listed in the database. Given its end-of-life status, upgrades would be limited to used parts.

The memory support for both DDR1 and DDR2 is a notable feature, as it allows the processor to be paired with either generation of RAM depending on the motherboard. However, the lack of memory bus specifications means that the maximum achievable bandwidth is unknown. The absence of ECC support further narrows its use to consumer or non-critical applications. The integrated graphics being a chipset feature means that the processor itself has no video output; a separate graphics solution is required. The socket 478 interface is a fixed platform, and the end-of-life status suggests that no new motherboards are being produced for it. For compatibility, any system using this processor must have a socket 478 motherboard with the appropriate chipset to support the integrated graphics feature.

Who Should Consider It

Given its single-core, single-thread design and a fixed 1.70 GHz clock, the Pentium 4-M 1.70 is suited for basic mobile computing tasks. These include web browsing, word processing, spreadsheets, and light email. The 512 KB L2 cache and 8 KB L1 cache are sufficient for simple applications that do not require large data sets. The low 30W TDP makes it suitable for thin and light laptops where battery life is a priority over performance. It is not recommended for gaming, video editing, or 3D rendering, as these workloads typically require multiple cores and higher clock speeds. The lack of a boost clock means that the processor cannot temporarily increase its frequency to handle bursty workloads, so it will maintain a constant performance level. The processor's end-of-life status means that new systems should not be built around it, but it could be used in retro or embedded applications where its low power draw is advantageous. Since the database records no benchmark scores, the actual performance for any workload cannot be quantified, but the specifications indicate an entry-level mobile processor.

The processor's single thread and lack of boost technology make it a poor fit for multitasking or parallel-heavy applications. Users who require responsiveness in modern operating systems with many background processes would likely find the 1.70 GHz clock insufficient. However, for a dedicated single-purpose task, such as a simple point-of-sale terminal or a lightweight thin client, the Pentium 4-M 1.70 could still function adequately. Its low TDP is a clear advantage in fanless or passively cooled designs, though the database does not confirm any such usage. Overall, this is a processor for the past, not for future-proofing.

Single-Thread vs Multi-Thread Behavior

The Pentium 4-M 1.70 has exactly one core and one thread. This means it cannot execute any multi-threaded workloads in parallel. Every application runs as a single thread, and the operating system must schedule all tasks onto that single execution unit. The base clock of 1.70 GHz is the only clock speed; there is no boost clock to provide additional performance when needed. This fixed clock ensures that the processor's performance is predictable, but it also means that there is no headroom for demanding tasks. The small caches—8 KB L1 and 512 KB L2—may cause performance bottlenecks in applications that repeatedly access large datasets, as the processor must fetch data from main memory more often. Since the processor is from the NetBurst architecture, it relies on high clock speeds to achieve performance, but at 1.70 GHz, it is on the lower end of that design's range. For single-threaded tasks, the processor's performance is determined by its clock speed and cache efficiency. Multi-threaded tasks are entirely unsupported, so any workload that can use multiple threads will see no benefit from this processor. In summary, the processor is strictly single-threaded, and its behavior is constant due to the lack of boost technology.

The implication for real workloads is that the processor will excel only in applications that are inherently sequential and do not require large working sets. Office documents, text editing, and simple calculations fit this profile. Conversely, modern web browsers with many tabs, video conferencing, or any form of content creation would suffer due to the lack of multi-threading and the modest clock. The fixed 1.70 GHz speed means that performance does not scale with demand, so users must accept a constant level of responsiveness. The small L2 cache further compounds this, as repeated memory accesses will incur latency. This processor is a clear example of an era before multi-core became mainstream, and its single-thread behavior reflects that.

How It Compares

The database does not list any nearest rivals for the Pentium 4-M 1.70. The only comparative metric is the percentile rank of 50, which places it at the median of all CPUs in the database. However, since the average benchmark score is 0, this percentile is not based on actual performance data. Without rival entries, it is impossible to state how this processor compares to other CPUs in terms of speed or efficiency. The percentile rank suggests that it sits in the middle of the distribution, but this is a default value in the absence of measurements. In the context of its own specifications, the processor is a low-power mobile part from 2002, so it would likely be outperformed by later desktop and mobile processors, but no specific comparisons are available. The lack of rival data means that any relative performance assessment is speculative. The processor's part number is SL5Z7, which is unique to this model, but it does not provide performance context.

The percentile rank of 50, while numerically exact, carries no weight because it is derived from an empty benchmark set. The database's average benchmark score of 0 reinforces that this processor has never been measured. In the absence of rival entries, the only statement that can be made is that the processor is not represented in any comparative analysis. This is a limitation of the database rather than a reflection of the processor's capabilities. For a user seeking a direct comparison, this entry offers no data points. The processor's specifications—single core, 1.70 GHz, 512 KB L2—remain the only basis for any external judgment, but they cannot be mapped to a relative position without rival scores.
