Intel Pentium 4 HT 641

The Intel Pentium 4 HT 641 is a Desktop-market processor from Intel, released on 2006-01-04, built on the NetBurst architecture under the Cedar Mill codename. The chip is designed for Intel Socket 775 and is listed as end-of-life. It provides 1 core and 2 threads, a base clock of 3.20, no recorded boost clock, a TDP of 86, and a 65 nm process node manufactured by Intel. The cache data lists 28 KB of L1 cache and 2 MB of L2 cache, with no L3 cache. Memory support covers DDR1, DDR2, and DDR3 over a dual-channel bus; ECC memory is not supported. The PCIe interface is Gen 2, integrated graphics are available only on certain motherboards as a chipset feature, and the multiplier is not unlocked.

Benchmark Performance

The FACT PACK contains no benchmark entries for the Intel Pentium 4 HT 641. The benchmark array is empty, so no application-level scores, no multi-thread scores, and no single-thread scores are available. The aggregate average benchmark score is 0. This zero value should be read as the absence of stored measurement records rather than as a measured performance result of zero operations per second. Because there are no benchmarks, the database cannot provide exact percentage gaps between this processor and any other processor.

The only quantitative performance-context value in the FACT PACK is `percentileVsAllCpus: 50`. This places the Pentium 4 HT 641 at the 50th percentile of all CPUs in the database. In a ranked distribution, that means the processor sits at the midpoint: half of the ranked sample falls below it and half falls above it. This median placement is the strongest statement the data supports about overall standing. It is not accompanied by rival scores or deltas, so it cannot be expressed as a specific margin over or behind a named part.

The absence of nearestRivals entries removes the clearest interpretation layer. Without rival names and without deltaPct values, the 50th percentile is an isolated rank. Benchmark results indicate that the processor occupies the middle of the database distribution, but whether that midpoint is closer to a particular rival cannot be determined from the available fields. The score of 0 reinforces that no measured anchor exists for a per-workload comparison.

In practical terms, the data permits no statements such as “30% ahead in multi-core” or “15% behind in single-thread.” No such numbers are present. The sole benchmark summary fields are the aggregate score of 0 and the percentile of 50. Those two fields place the processor at the center of the overall CPU population in the database, with no supporting benchmark records to refine the position.

Single-Thread vs Multi-Thread Behavior

The Intel Pentium 4 HT 641 is a 1-core processor with 2 threads. The name includes “HT,” and the thread count is configured as 2, which indicates that the single physical core exposes two hardware threads. The base clock is 3.20, and the FACT PACK records no boost clock. This makes 3.20 the only clock speed listed for the part.

Single-threaded workloads can use the processor’s single physical core. The cache hierarchy listed for that core is 28 KB of L1 cache and 2 MB of L2 cache, with no L3 cache. A 2 MB L2 cache is the largest cache field in the FACT PACK after the missing L3. The single-thread behavior is therefore characterized by one core, one base clock figure, and that L1/L2 cache arrangement. Since no boost clock is recorded, the data does not describe any automatic frequency increase beyond 3.20.

Multi-threaded behavior is defined by the 2-thread limit. The processor can schedule two threads, but it does not offer additional physical cores. Workloads that require more than two simultaneous threads would exceed the listed thread count. The NetBurst architecture, the Cedar Mill codename, and the 65 nm process node are the implementation details behind that single-core, dual-thread design. The 188 million transistor count and 81 mm² die size add further silicon-level context to the core layout.

There are no measured single-thread or multi-thread scores to separate the two behaviors. The aggregate percentile of 50 does not distinguish between them. The only structural facts are the 1-core/2-thread split, the 3.20 base clock, the absence of a boost clock, and the cache capacities. Those facts suggest that lightly threaded work has one core available, while workloads that can use two threads have one additional logical thread but no extra physical core.

Platform and Compatibility

The platform foundation is Intel Socket 775. Intel is listed as both the manufacturer and the foundry. The silicon is built on a 65 nm process node, with 188 million transistors and an 81 mm² die size. The architecture is NetBurst, and the generation field is “Pentium 4 HT (Cedar Mill).”

Memory support is broad across older memory generations: DDR1, DDR2, and DDR3 are all listed. The memory bus is dual-channel, so the platform can pair two channels of memory if the motherboard provides the appropriate slots and memory type. No memory bandwidth value is present in the FACT PACK, so the data does not quantify maximum transfer rate. ECC memory support is false, meaning the processor is not listed with ECC capability.

The PCIe interface is Gen 2. This defines the expansion capability listed for the processor’s platform. Integrated graphics are not listed as a core feature of the CPU itself. The FACT PACK states that integrated graphics are available “On certain motherboards (Chipset feature),” which means display output depends on the motherboard chipset rather than being a guaranteed feature of the processor package. A system built around this processor would need a board whose chipset provides that feature if integrated display output is required.

The processor is classified as Desktop and is marked end-of-life. Its release date is 2006-01-04. The multiplier is not unlocked, so the 3.20 base clock is the clock data provided in the record, and multiplier-based overclocking is not enabled according to the FACT PACK. The part number listed is SL94XSL9KF. The production status of end-of-life means the processor is no longer in active production, so any platform integration would rely on existing Socket 775 boards and one of the listed memory types. The socket, memory support list, PCIe generation, and chipset-dependent graphics feature are the main compatibility boundaries in the data.

How It Compares

The FACT PACK lists no nearestRivals entries for the Intel Pentium 4 HT 641. The nearestRivals array is empty, meaning there are no rival names, rival scores, or deltaPct values to cite. Consequently, no exact percentage comparison can be made to any specific processor in the database.

The only comparative figure available is the 50th percentile standing across all CPUs. This gives the processor a median position in the overall distribution. In a nearest-rival framework, a median position would be interpreted relative to neighboring entries, but no neighbors are present in the FACT PACK. The data therefore supports a single broad claim: the processor sits at the midpoint of the database’s CPU rankings. It does not support claims that this chip beats or loses to a particular rival by a specific margin.

Since no rival records exist, there are no per-rival paragraphs to construct. The empty nearestRivals field is the complete comparison dataset. Benchmark results indicate that any attempt to name a competing processor would be unsupported by the FACT PACK. The only meaningful comparative signal is the 50th percentile, and that signal is not anchored to measurable rival scores.

Who Should Consider It

With an aggregate benchmark score of 0 and no stored benchmark records, the data cannot assign the Intel Pentium 4 HT 641 a definitive workload ranking. The 50th percentile places it at the center of the database population, neither at the extreme low end nor at the top. That central rank is the only score-based evidence available for workload positioning.

For office workloads, the processor’s 1-core, 2-thread design and 3.20 base clock are the relevant characteristics. Office applications that do not require more than two threads could operate within the listed thread count. The dual-channel memory support for DDR1, DDR2, or DDR3 indicates that this is a platform aimed at systems using one of those memory generations rather than a modern memory standard. The end-of-life status further limits the context to older Socket 775 systems.

For gaming, the FACT PACK contains no game-specific benchmark scores. The only data points are 1 core, 2 threads, a 3.20 base clock, no L3 cache, and no integrated graphics on the processor itself. Games that require more than two threads would be constrained by the 2-thread limit. Games that require integrated graphics would need to use a motherboard with the chipset-based graphics feature, because the CPU’s integrated graphics field is not a guaranteed processor feature.

For creation workloads, the lack of additional physical cores is the main limitation. The processor has one core and two threads, so heavily parallel rendering, video, or encoding tasks would have no more than two threads available. The 28 KB L1 cache and 2 MB L2 cache are the only cache resources listed. The 3.20 base clock is the sole clock-speed figure, since no boost clock is recorded.

The 50th percentile position means the processor is a middle-of-database part when all CPUs are ranked together. For a user with a Socket 775 platform and a workload that fits within one core and two threads, the listed characteristics are compatible. For users whose workloads scale well beyond two threads or depend on guaranteed integrated graphics, the data provides no benchmark evidence that this processor would be a suitable match.
