About Intel Pentium 4-M 1.40
The Intel Pentium 4-M 1.40 is a mobile processor built by Intel around the NetBurst architecture, with the codename Northwood. It has 1 core and 1 thread, a base clock of 1400.00 MHz, and no boost clock. The 130 nm process node contains 55 million transistors on a 131 mm² die. The cache arrangement is 8 KB of L1 and 512 KB of L2, with no L3 cache documented. Memory support is DDR1 and DDR2, without ECC. The processor uses Intel Socket 478 and targets the Mobile market segment. Integrated graphics are present only "On certain motherboards (Chipset feature)". The release date is 2002-04-22 and the production status is End-of-life. The benchmark list is empty, the average benchmark score is 0, and the percentile versus all CPUs is 50.
Who Should Consider It
Because the benchmarks array is empty, the recommendations below are derived from the hardware record rather than measured scores. The processor offers one execution thread, so the intended workload is one that does not require parallel CPU resources. Office-oriented work that is largely single-threaded and does not need a second thread would rely entirely on the 1400.00 MHz base clock and the 512 KB L2 cache. For creation workloads, the single-thread layout limits concurrent processing; any task that would otherwise split across threads must run on one logical processor. Gaming is harder to place from the data: the CPU lists no integrated graphics as a processor feature, and the only graphics note is a chipset feature on certain motherboards. That means any gaming use would depend on the platform's chipset graphics or a separate graphics path, neither of which the fact pack quantifies. The 21 W TDP and Mobile segment suggest a portable, low-power system rather than a high-throughput desktop part. The locked multiplier reinforces that this is a fixed-frequency mobile product, so the 1400.00 MHz base clock is the only operating speed available. In short, this part is suited to a workload profile of single-threaded tasks on a Socket 478 mobile platform, with no multi-thread scaling.
Single-Thread vs Multi-Thread Behavior
The defining structural fact is 1 core and 1 thread. There is no boost clock, so the 1400.00 MHz base clock is the only operating frequency in the record. A single thread means that all work passes through one execution context; the 8 KB L1 and 512 KB L2 are the sole cache resources for that context. Multi-thread behavior, as a practical matter, does not exist on this processor. A program written for multiple threads would still be limited to the one hardware thread, so that program would have to execute sequentially on the single available logical processor. The percentileVsAllCpus figure of 50 places the processor at the midpoint of the database's CPU population, but that figure does not split into single-thread and multi-thread scores because no such scores are present. The absence of a boost clock also means there is no documented higher-frequency state to assist short bursts of single-thread work. The data tells a clear story: single-thread execution is the only mode, and its absolute quality cannot be measured from the empty benchmark record.
How It Compares
The nearestRivals array in the record is empty. There are no rival names, no rival scores, and no deltaPct values. Consequently, the record does not position the Pentium 4-M 1.40 against specific competing products. The only comparative signal is percentileVsAllCpus, which is 50. That indicates the midpoint in the database distribution, but because avgBenchmarkScore is 0 and benchmarks is empty, the percentile is not reinforced by measured performance. No percentage deltas to rivals can be computed from this data. In effect, the processor is unranked against named rivals; the empty nearestRivals field is the complete comparison record. Anyone seeking a head-to-head evaluation would need data that is simply not present in this processor's entry.
FAQ
Q: Does the Pentium 4-M 1.40 have integrated graphics on the CPU?
A: The data describes integrated graphics as "On certain motherboards (Chipset feature)". That indicates graphics are tied to a motherboard chipset feature on certain boards, not a documented CPU-internal GPU.
Q: What memory types are supported?
A: The processor supports DDR1 and DDR2 memory. ECC memory is not supported. The record does not list a memory bus width or memory bandwidth.
Q: How many cores and threads does it have?
A: It has 1 core and 1 thread. The base clock is 1400.00 MHz and boostClock is null, so no boost frequency is documented.
Q: Is the multiplier unlocked?
A: No. The multiplierUnlocked field is false, meaning the clock multiplier is locked in the supplied data.
Q: What socket and manufacturing process does it use?
A: It uses Intel Socket 478 and a 130 nm process. The architecture is NetBurst with the codename Northwood.
Q: Is this processor still in production?
A: No. The production status is End-of-life. The release date is 2002-04-22 and the market segment is Mobile.
Power and Thermals
The TDP is 21 W, which is the only thermal figure in the record. This defines the heat the cooling system must handle under a full-load design condition. The data does not include a cooler size, a measured temperature, or a power consumption curve. The 130 nm process node and the 55 million transistor count are the manufacturing details that contribute to that 21 W envelope, though the record does not model their interaction. No boost clock is listed, so there is no higher-frequency state that would impose an additional thermal load beyond the base operational state. The mobile market segment is consistent with a 21 W thermal design, but the record does not state chassis or fan requirements. The locked multiplier also means the frequency cannot be raised by user ratio adjustment, which keeps the thermal profile tied to the 1400.00 MHz base clock.
Platform and Compatibility
The platform foundation is Intel Socket 478. The memory support includes DDR1 and DDR2, while ECC memory is not supported. The memory bus and memory bandwidth fields are null, so the record does not quantify data throughput to memory. PCIe support is also null, meaning no PCIe version or lane counts are documented. Display connectivity is not built into the CPU; integrated graphics are "On certain motherboards (Chipset feature)". The market segment is Mobile, the production status is End-of-life, and the release date is 2002-04-22. The multiplier is locked, so the processor does not offer unlocked ratio adjustment. The part number SL5ZHSL5ZW identifies this SKU. Because nearestRivals is empty, no compatible upgrade processors are listed in the data; the upgrade path beyond this specific Socket 478 record is not documented.
Benchmark Performance
The benchmark performance section of the record is sparse. The benchmarks array contains no entries, and the avgBenchmarkScore is 0. The only quantitative ranking is percentileVsAllCpus at 50, which puts the processor at the 50th percentile among all CPUs in the database. There are no nearestRivals, so exact percentage deltas to rivals cannot be produced. The performance-relevant hardware numbers are the 1400.00 MHz base clock, 1 core, 1 thread, 8 KB L1, and 512 KB L2. With an empty benchmark set, the average score is structurally zero rather than a measured result. Therefore any statement about relative performance must come from the architectural facts: a single-threaded NetBurst core running at 1400.00 MHz with 512 KB of L2 and DDR1/DDR2 memory support. The 50th percentile remains the only positional data, and it is unaccompanied by rival deltas or benchmark averages.
