Intel Mobile Pentium 4 2.66

Intel Mobile Pentium 4 2.66 is an end-of-life mobile processor from Intel. It was released on 2003-06-10 and carries the part number SL724. The chip belongs to the NetBurst architecture, codename Northwood, and the production process is Intel’s 130 nm node with 55 million transistors and a 131 mm² die. Its cache layout is 8 KB L1 and 512 KB L2, with no L3 listed. It has one core and two threads, a base clock of 2.67 GHz, and no boost clock. The memory support is DDR1 and DDR2, ECC is not enabled, and the socket is Intel Socket 478. The field for integrated graphics reads "On certain motherboards (Chipset feature)". The series field is null, the market segment is mobile, and the generation is "Mobile Pentium 4 (Northwood)".

Benchmark Performance

No benchmark rows are attached to this entry: the benchmarks array is empty. The avgBenchmarkScore field is 0, and the nearestRivals list is empty, so there are no scores and no deltaPct values to analyze. In the absence of measured scores, the only performance-relevant facts are structural: one physical core, two logical threads, 2.67 GHz base clock, no boost clock, 8 KB L1 cache, and 512 KB L2 cache.

Because the benchmark array contains no entries, the database does not support any statement such as "x percent faster" or "y percent slower". The percentileVsAllCpus field is 50, which nominally places this processor at the midpoint of the database distribution, but with an average benchmark score of zero, that midpoint is not backed by a reported result. The absence of a boost clock means the processor's frequency is fixed at 2.67 GHz. A two-thread single-core arrangement is the maximum parallel execution capability described by the entry. No L3 or v-cache field is populated, so no extra cache level can be credited. These facts describe the part's compute resources, but they are not a substitute for benchmark numbers.

Power and Thermals

This processor has a TDP of 66 W. That single figure defines the thermal envelope. The part is classed as mobile, and the TDP is the only power-related number in the fact pack; there are no other wattage figures for coolers or platform components. Because the clock is fixed at 2.67 GHz with no boost frequency, the frequency side of thermal load has no boost state in the data.

The underlying process data is a 130 nm process, 55 million transistors, and a 131 mm² die. A 66 W TDP on that process node indicates the heat sink and chassis cooling need to deal with a 66 W continuous design target; however, the database does not list any specific cooler class. Production status is end-of-life.

Platform and Compatibility

The socket is Intel Socket 478. Memory support is DDR1 and DDR2, with no memory bus width or bandwidth listed. ECC memory is not supported. The pcie field is null, so the part's PCIe lanes are not specified in the fact pack. Integrated graphics is described as "On certain motherboards (Chipset feature)", meaning graphics presence depends on the motherboard chipset, not on a processor-integrated GPU.

The multiplier is locked, so the user cannot adjust multiplier settings. The processor is produced by Intel and uses the NetBurst architecture codenamed Northwood. Its generation is given as "Mobile Pentium 4 (Northwood)" and its series field is null. The part number is SL724. There is no L3 cache field populated, and the memory bus field is empty; any motherboard using this CPU would need to be an Intel Socket 478 board that supports DDR1 or DDR2 as listed.

Upgrade path is constrained by the listed compatibility facts: a compatible replacement must use Intel Socket 478, must work with the system's DDR1/DDR2 memory, must not require ECC, and would be limited by the locked multiplier. The fact pack lists no alternative processors, so no specific upgrade recommendations can be derived.

How It Compares

The nearestRivals array in the fact pack is empty. There are no rival names, no rival scores, and no deltaPct values to report. Consequently, this section cannot offer a per-rival paragraph for any specific competitor. The only positional field is percentileVsAllCpus, which is 50. That rank puts the part at the midpoint of all CPUs in the database, but because the avgBenchmarkScore is 0, the rank is not associated with a measured score.

Comparing against the database as a whole, the available facts are the same as the specification sheet: it is a one-core, two-thread mobile NetBurst chip with a 2.67 GHz base clock, 512 KB L2 cache, Intel Socket 478, and DDR1/DDR2 support. Without benchmark scores, any comparison to the rest of the field would be qualitative at best and would have to rely on specifications only, not on deltaPct. The fact pack provides no percentage deltas, so no exact "ahead of" or "behind" statements are possible. There are no nearest entries; the comparison data set is empty.

Who Should Consider It

Given the lack of benchmark scores, this processor cannot be recommended on measured performance. The database entry has no gaming, creation, or office benchmark rows, so workload recommendations cannot cite percentages or frame rates. From a compatibility standpoint, the processor is for someone already operating an Intel Socket 478 mobile system that uses DDR1 or DDR2 memory and does not require ECC.

The two threads and single core mean the logical processor count is exactly two. A locked multiplier means no multiplier-overclocking consideration. No boost clock means the operating frequency is fixed. The TDP of 66 W is the thermal constraint. Workloads that are very lightweight in parallel demand could align with a two-thread single core, but the fact pack contains no productivity scores to prove this. Similarly, gaming and content creation are not supported by any benchmark data.

The integrated graphics field is a chipset feature, so a user should look to the motherboard chipset for display output, not to the CPU. Anyone needing ECC memory, PCIe lane specifications, or on-die graphics will not find support in this entry. The end-of-life production status tells a prospective user that new units are no longer in production. The strongest use case indicated by the data is a legacy Intel Socket 478 mobile system: one core, two threads, 2.67 GHz, 512 KB L2, DDR1/DDR2 memory, and a 66 W thermal envelope. For that narrow set of platform requirements, the specifications match; beyond that, the absence of benchmark records prevents further recommendations.
