Intel Pentium 4 HT 520

Intel Pentium 4 HT 520 is a desktop processor from Intel built on the NetBurst architecture under the Prescott codename, released on 2004-06-20. It has one physical core, two threads, a 2.93 GHz base clock, and no boost clock in the data. Intel manufactures it on a 90 nm process with 125 million transistors and a 109 mm² die. The socket is Intel Socket 775, the market segment is desktop, and the production status is end-of-life. The part number is SL7J4. The most consequential database facts are negative: the benchmarks array is empty, the average benchmark score is 0, the percentile versus all CPUs is 50, and nearestRivals is an empty list.

Benchmark Performance

The only benchmark-like number in the FACT PACK is the average benchmark score of 0. That zero is not a measured performance result; it is the value reported when no benchmark entries exist. The percentileVsAllCpus field gives a 50, placing this processor at the 50th percentile of all CPUs in the database. Without any entries in the benchmarks array, the percentile is a positional marker with no supporting scores behind it.

Exact percentage deltas against nearest rivals cannot be derived because no nearestRivals rows are included. The FACT PACK has no deltaPct values, rival scores, or rival names. The data says, in effect, that the relative ranking of this CPU is unknown from benchmark tests, even though the database routine has assigned it the middle percentile. A reasonable reading: the 50th percentile does not grade this silicon; it grades the completeness of this record. That is an important distinction for anyone using the site.

A 50th percentile is often read as “average.” Here it cannot be validated. There is no measured workload evidence to say the processor is average, above average, or below average. The record simply lacks the underlying data points. Therefore, the benchmark performance section is best understood as missing data rather than as a verdict.

How It Compares

The nearestRivals array is empty. There are therefore no rival names, no rival scores, and no percentage deltas to report. The only comparative statistic in the FACT PACK is the 50th percentile versus all CPUs. That is a database-wide position, not a head-to-head measurement.

Without nearest-rival entries, any claim such as “ahead of X” or “behind X” would be unsupported. The absence of rivals also means there are no deltaPct values to indicate proportional differences, no rival architecture notes, and no generation-to-generation positioning. This section must remain silent on direct comparisons until the record contains rival data.

Who Should Consider It

Using only the data, this processor is suited to workloads that can live within one physical core and two logical threads. The base clock is 2.93 GHz, and because no boost clock is present, the processor has no higher advertised frequency state. Applications that depend on a single thread have the core to themselves; applications that can use two threads have two logical threads, but still share the same one core. The data does not include scores for gaming, creation apps, or office suites, so any workload-specific recommendation has to be based on thread count and clock rather than measured performance.

Creation workloads such as video rendering, 3D modelling, or compilation tend to need multiple independent cores and high memory throughput. The FACT PACK shows dual-channel memory support but does not include a memory bandwidth number. The processor’s one core makes it a questionable fit for heavily parallel work, though the data does not contain benchmark evidence either way. Single-thread office tasks are more aligned with the one-core/two-thread design, but no office benchmark score is present.

Gaming is the least supported recommendation. The record contains no graphics benchmark, no integrated GPU, and no game score. The integrated graphics field refers to “On certain motherboards (Chipset feature)”, meaning any display output would come from the motherboard chipset, not from this processor. A prospective user would be relying on the motherboard’s chipset rather than on a device-side graphics unit.

Because production status is end-of-life, any consideration must also account for the fact that the data offers no indication of ongoing production. The multiplier is locked, so the CPU ratio is not unlocked. That further narrows the audience to users who do not intend to change the multiplier.

FAQ

Q: What socket does the Pentium 4 HT 520 use?

A: Intel Socket 775.

Q: What are the core and thread counts?

A: One core and two threads. The product name contains “HT”, and the data lists two threads.

Q: What memory does it support?

A: The memory support field lists DDR1, DDR2, and DDR3 with a dual-channel memory bus. ECC memory is not supported. No memory bandwidth figure is listed.

Q: Does the processor have integrated graphics?

A: The processor does not list integrated graphics as a core feature. The integrated graphics field says “On certain motherboards (Chipset feature)”, meaning the motherboard chipset may provide graphics.

Q: Is the multiplier unlocked?

A: No. The multiplierUnlocked field is false.

Q: What are the process node and cache figures?

A: The process node is 90 nm. The die is 109 mm² and contains 125 million transistors. Cache is 16 KB L1 and 1 MB L2, with no L3 cache listed.

Platform and Compatibility

The platform is built around Intel Socket 775. The processor uses the NetBurst architecture with the Prescott codename and is manufactured by Intel on a 90 nm process with a 109 mm² die and 125 million transistors. The memory support field lists DDR1, DDR2 and DDR3, connected through a dual-channel memory bus. ECC memory is marked false. PCIe support is Gen 2. Integrated graphics are available only as “On certain motherboards (Chipset feature)”. The multiplier is locked, so the CPU ratio is not unlocked. The part number is SL7J4.

The memory support field is a list of standards, not a statement of simultaneous support. The data does not say that all three DDR generations can be used at once; it simply records DDR1, DDR2, and DDR3 as supported memory types. The absence of a memory bandwidth number means throughput comparisons cannot be made from the FACT PACK.

Upgrade path: the FACT PACK contains no other Socket 775 processors, and nearestRivals is empty. Therefore, a data-driven upgrade path cannot be constructed from this page. The only compatibility facts available are the socket, memory types, PCIe generation, and ECC support. Since the production status is end-of-life, the data does not indicate availability of new units.

Single-Thread vs Multi-Thread Behavior

The split here is structurally wide: one physical core supports two logical threads. In single-thread workloads, the sole core can run one instruction stream at 2.93 GHz, the only clock listed. No boost clock appears, so the record gives no higher frequency to reason about. In multi-thread workloads, two threads can be scheduled, but they share the same physical core. That shared arrangement means the performance ceiling for two threads is not double the single-thread ceiling; the data does not quantify the improvement.

The cache layout strengthens the single-thread story: 16 KB L1 and 1 MB L2 with no L3. The thread count of 2 adds a potential second logical path, but the L2 is not a per-core split because there is only one physical core. Real workloads that are latency-sensitive and single-threaded have a clear clock figure to assess. Real workloads that are throughput-sensitive across many threads have no physical cores beyond the one to engage.

The locked multiplier is also relevant here. Because the multiplier is not unlocked, the only clock in the record, 2.93 GHz, is the clock users can expect. The data does not provide any alternative multiplier state or boost state.

Power and Thermals

The one thermal rating in the FACT PACK is 84 W TDP. This places the cooling requirement in the 84-watt class; the platform needs a cooling solution designed to dissipate that heat. The 90 nm process, 125 million transistors, and 109 mm² die are the physical details that would inform heat density, but no thermals beyond TDP are given.

The absence of a boost clock means thermal load is tied to the base 2.93 GHz in the data. No wattage figures other than 84 W exist. A cooler for this processor must match the Socket 775 mounting interface and the 84 W thermal envelope, though the FACT PACK lists no cooler-specific details. The integrated-graphics situation is motherboard-dependent, so any additional heat from the chipset is outside the processor TDP. The data does not include fan speeds, thermal resistance, or cooling-tier labels.
