About Intel Pentium 4 505J

The Intel Pentium 4 505J is a desktop processor from Intel, built on the NetBurst architecture under the Prescott codename. It has 1 core, 1 thread, a 2.66 GHz base clock, no boost clock, and a TDP of 84 W. Fabricated on Intel's 90 nm process, it contains 125 million transistors on a 109 mm² die and fits Intel Socket 775. The database entry carries no benchmarks, no nearest rivals, a 50th percentile rank, and an average benchmark score of 0.

Benchmark Performance

The benchmark section of the data is empty. The benchmarks array has no entries, and the average benchmark score is 0. There is no measured score to quote for any workload. The nearestRivals array is also empty, so there are no rival names, scores, or deltaPct values with which to build a comparison. The only relative figure is percentileVsAllCpus, which is 50. A 50th percentile is the midpoint of a ranked distribution, so this value places the processor in the middle of the all-CPU list if the percentile is taken as a valid placement. That middle position is difficult to reconcile with an average benchmark score of 0, because a score of 0 usually indicates that no measured results exist. The two fields together imply that the percentile is likely a catalog-level placeholder rather than a calculated outcome.

No percentage advantage or deficit can be derived from the FACT PACK for this processor. Statements such as "ahead of" or "behind" a named rival cannot be supported. The architecture, codename, and process information identify the design as NetBurst/Prescott at 90 nm, but those facts do not translate into benchmark speed. The data's central finding is negative: this entry provides no evidence for comparing the Pentium 4 505J with any other processor. The 50th percentile remains the only quantitative signal, and its meaning is unclear without supporting scores.

Power and Thermals

The only power-related value in the FACT PACK is a TDP of 84 W. This is a design thermal limit, not a measured consumption figure. The data does not include runtime wattage, cooler specifications, or maximum temperature. A TDP of 84 implies that a cooling solution must be able to dissipate that thermal class of heat, but the exact cooling tier is not described. The 90 nm process node, 125 million transistors, and 109 mm² die size describe the physical construction; they characterize the silicon area and density but do not describe thermals directly. The production status is end-of-life, so the entry does not contain current platform-level thermal guidance.

The multiplier is locked, which means the data does not provide a multiplier-based overclocking path. There is no boost clock, so there is no automatic higher-frequency thermal peak beyond the 2.66 GHz base clock. The integrated graphics field reads "On certain motherboards (Chipset feature)"; this places any display engine on the motherboard chipset, so the CPU's thermal envelope may not include graphics hardware in those configurations. Without measurements, the only definitive statement is that the processor is rated at a TDP of 84 W, and the data does not connect that rating to a named cooler.

Who Should Consider It

Because the benchmark array is empty and the average score is 0, no score-driven recommendation can be made for gaming, creation, or office workloads. The structural facts are clearer. The processor has 1 core and 1 thread, so multi-threaded applications cannot use a second hardware thread. A single-threaded workload is the only kind that can occupy the processor's full execution resource. The base clock is 2.66 GHz, and there is no boost clock, so that single thread runs at a fixed listed frequency. The 16 KB L1 cache and 1 MB L2 cache are the only cache resources listed.

The desktop market segment points to a consumer desktop context. The end-of-life production status suggests the processor is not a current retail platform. Memory support for DDR1, DDR2, and DDR3 provides motherboard-level flexibility, but no motherboard models are named. No workload-specific scores exist to justify recommending the 505J for any particular application. The most defensible statement is that the 505J is a single-thread-oriented desktop processor with an unmeasured performance profile. Software that expects parallel execution will find no parallel hardware in the data, while serial workloads will find a fixed 2.66 GHz thread.

FAQ

Q: What are the core and thread counts of the Pentium 4 505J?

A: It has 1 core and 1 thread.

Q: What is the base clock speed, and is there a boost clock?

A: The base clock is 2.66 GHz, and the FACT PACK lists no boost clock.

Q: What cache levels are listed?

A: The data lists a 16 KB L1 cache and a 1 MB L2 cache; no L3 cache is listed.

Q: What memory types does it support?

A: It supports DDR1, DDR2, and DDR3 memory over a dual-channel memory bus.

Q: Does the processor support ECC memory?

A: No; the FACT PACK lists ECC memory support as false.

Q: Are there any benchmark scores or nearest rivals in the data?

A: No. The benchmarks array is empty, the average benchmark score is 0, and the nearestRivals array is empty.

How It Compares

The nearestRivals array is empty. There are no rival names, scores, or deltaPct values to quote. The only comparative field is percentileVsAllCpus at 50. That value places the processor at the median of the all-CPU distribution if the percentile is considered valid. However, because no rivals are enumerated, the CPUs around that median are unknown. The data cannot support a statement about being ahead of or behind a specific rival. An empty nearestRivals list is not evidence that the processor has no competitors; it simply means the database does not define them. The comparison section is therefore a null result. The 50th percentile remains the sole relative data point, but its path to that position is undocumented.

Platform and Compatibility

The processor uses Intel Socket 775. It is a desktop-market part with a locked multiplier, so the data does not allow multiplier-based frequency changes. Memory support spans DDR1, DDR2, and DDR3 with a dual-channel memory bus. ECC memory support is false. PCIe is listed as Gen 2. The integrated graphics field says "On certain motherboards (Chipset feature)", meaning display output depends on the motherboard chipset rather than the CPU. The part number is SL85U.

Production status is end-of-life, and the release date is 2004-11-30. That date places the processor at the beginning of the Socket 775 timeline in this dataset, though no other Socket 775 CPUs are listed. An upgrade path cannot be enumerated because the FACT PACK does not list compatible processors. The 90 nm process, 125 million transistors, and 109 mm² die were built by Intel. The architecture is NetBurst and the codename is Prescott. In summary, the platform facts define the physical context: Socket 775, dual-channel DDR-family memory, PCIe Gen 2, no ECC, and no unlocked multiplier.

Single-Thread vs Multi-Thread Behavior

The 505J has 1 core and 1 thread. There is no multi-thread split in this processor; exactly one hardware thread is available to all workloads. A single-threaded task can use that thread exclusively. A multi-threaded workload has no additional core or thread to engage, so all parallel work would have to share the same thread. The base clock is 2.66 GHz, and no boost clock is listed, so the data does not describe a higher-frequency turbo state. The 16 KB L1 cache and 1 MB L2 cache are the cache resources available to that one thread.

The NetBurst architecture, Prescott codename, 90 nm process, 125 million transistors, and 109 mm² die are the listed design facts. There are no separate single-thread or multi-thread benchmark indices. The relative strength of the single thread versus a hypothetical multi-thread design is therefore not measurable from this entry. What the data shows structurally is that all execution is concentrated into one thread. Software written for parallelism will not find additional hardware threads in the 505J. Software written for serial execution will see a fixed 2.66 GHz single-threaded processor, with no measured score to confirm its speed.
