Intel Pentium 4 2.66

Intel Pentium 4 2.66 is a desktop processor from Intel, built on NetBurst architecture under the Northwood codename. The product data lists 1 core and 1 thread, with a 2.66 GHz base clock and no boost clock. It is manufactured on Intel's 130 nm process, containing 55 million transistors on a 146 mm² die. The processor uses Intel Socket 478 and is categorized in the Desktop market segment. Its production status is End-of-life, and the release date is 2002-08-24. The cache layout is 8 KB L1 and 512 KB L2, with no L3 cache. In the database, the benchmarks list is empty, the average benchmark score is 0, and the percentile vs all CPUs is 50.

Benchmark Performance

Benchmark results for this processor are not present in the FACT PACK. The benchmarks array has no entries, and the average benchmark score reports as 0. Because there are no recorded scores, the usual metrics for single-thread and multi-thread performance cannot be stated from this data. The absence of measured results is itself a finding: any comparison that relies on benchmark performance is not supported by the record.

The nearestRivals array is also empty. That means there are no rival names, no rival scores, and no deltaPct values in the FACT PACK. Consequently, no exact percentage lead or deficit versus a named competitor can be computed. The only cross-CPU numeric signal is the 50th percentile standing among all CPUs. A processor at the 50th percentile sits at the midpoint of the database distribution. This suggests a middle-of-the-road placement, but with zero benchmark entries behind it, the percentile is not accompanied by workload-based evidence.

The chip's listed characteristics align with a single-threaded design: 1 core, 1 thread, and a 2.66 GHz base clock. There is no boost clock, so all sustained activity runs at the listed base frequency. The L1 cache is 8 KB and the L2 cache is 512 KB, with no L3 cache. The memory support is given as DDR1 and DDR2, and ECC memory is not supported. These items describe the platform, but they do not substitute for benchmark scores. No score exists to interpret against rivals, so the only quantitative position is the 50th percentile.

Who Should Consider It

Given the listed configuration, this processor is not a match for heavy multi-threaded workloads. It has 1 core and 1 thread, so applications that need parallel execution cannot use resources that are not present. The data does not include any multi-thread benchmark result to argue otherwise.

For office and light productivity, the 2.66 GHz base clock and 512 KB L2 cache are the available resources. The 50th percentile indicates it is not at the very bottom of the database, but the average benchmark score of 0 leaves no measured evidence of real-world responsiveness. A system built around this processor should be approached as a single-tasking desktop part.

For gaming, the absence of benchmark scores is notable. There are no gaming results in the FACT PACK. The processor's 1-core and 1-thread structure limits any workload that expects more than one thread. The only graphics support listed is a chipset feature on certain motherboards, not integrated graphics within the CPU. This affects the display path for any system using this processor.

Creation workloads such as rendering and compositing typically require multiple threads. With 1 thread, this processor has no capacity for parallel execution in that role. The NetBurst architecture, Northwood codename, and 130 nm process are listed, but they do not change the core and thread counts. The production status is End-of-life, so this is not a forward-looking creation part; it belongs to the Desktop market segment with a 2002-08-24 release date.

Power and Thermals

TDP is listed at 110W. This is the thermal figure a cooling solution must be able to handle. The 130 nm process node and 55 million transistor count are process-level facts, and the 146 mm² die gives the thermal surface area. Because the processor has no boost clock, the power envelope is tied to the 2.66 GHz base state.

A 110W TDP implies an active cooling solution. A passive or very low-profile setup is not a sensible match for that thermal class. The processor uses Intel Socket 478, so the cooler must be compatible with that socket. The production status is End-of-life, meaning thermal replacement is a maintenance concern for existing systems rather than a new-build selection. The data does not list any cooler model or size, so only the 110W figure defines the requirement.

Platform and Compatibility

The platform begins with Intel Socket 478. Memory support is listed as DDR1 and DDR2. ECC memory is not supported, so the memory path is non-ECC. The PCIe field is null, meaning no PCIe version or lane information is available in the FACT PACK. Memory bus width and bandwidth are also not listed, so memory throughput cannot be quantified.

The CPU itself has no integrated graphics. The FACT PACK lists integrated graphics as "On certain motherboards (Chipset feature)", which places graphics capability on the motherboard chipset rather than inside the processor. This is important for system planning because display output depends on the board. The multiplier is not unlocked, with multiplierUnlocked set to false. There is no boost clock, so the operating frequency is fixed to the 2.66 GHz base clock.

As an End-of-life Desktop product released 2002-08-24, the upgrade path is limited to Socket 478 boards with DDR1 or DDR2 support. Any replacement processor must match the same socket and memory class. The lack of L3 cache and the presence of only 8 KB L1 and 512 KB L2 define the cache architecture. The processor is not unlocked, so its frequency is not adjustable through the multiplier according to the data.

How It Compares

The nearestRivals array in the FACT PACK is empty, so no named rival comparisons can be made. The record contains no rival model names, no rival scores, and no deltaPct values. Therefore, no percentage margin for this Pentium 4 2.66 against another specific product can be reported.

The only comparative placement is the 50th percentile vs all CPUs. That is a median position in the database distribution. It does not align the processor with any specific competitor. Without nearestRivals records, any claim such as "ahead of the competitor" or "behind the competitor" would be unsupported data.

The absence of benchmark entries reinforces this limitation. Comparison normally requires scores, and the scores list is empty. The average benchmark score of 0 is consistent with a record that has no measured performance data. The 50th percentile is the only number that places this processor in relation to the rest of the CPU database.
