Intel Pentium 4 HT 672

The Intel Pentium 4 HT 672 is a desktop processor built on the NetBurst architecture with the Prescott codename, fabricated on a 90 nm process at Intel. It pairs a single physical core with two logical threads, running at a fixed 3.80 GHz base clock with no boost capability, and carries a TDP of 84 W. Released on 2005-11-13 and now end-of-life, the chip uses Intel Socket 775 and supports DDR1, DDR2, and DDR3 memory in a dual-channel configuration. In this database, the processor has no recorded benchmark scores — its average benchmark score is 0, and its percentile ranking against all CPUs is 50 — so the following analysis is based on its structural specifications and platform features rather than measured performance data.

Benchmark Performance

The benchmark data for the Pentium 4 HT 672 is entirely absent from the database. The benchmarks array is empty, and the average benchmark score is recorded as 0, which indicates that no workload results have been ingested for this part. The only positional metric available is the percentileVsAllCpus field, which places the processor at the 50th percentile. That value means the chip sits at the exact median of all CPUs tracked in the database — half of all recorded processors rank above it, and half rank below it. However, because the nearestRivals array is empty, there are no direct competitor scores and no deltaPct values to compute percentage advantages or deficits against specific models.

The lack of measured data does not erase the structural signals. A single core with two threads at 3.80 GHz, backed by a 2 MB L2 cache, defines a performance envelope that is entirely clock-driven. The 50th percentile placement, while not tied to a numeric score, suggests that the processor occupies a middle position in the historical CPU landscape. Without rival deltas, any statement about being "ahead of" or "behind" a specific chip cannot be made from this dataset. The average score of 0 is a placeholder meaning "no data," not a literal zero-performance result.

Platform and Compatibility

The Pentium 4 HT 672 is built for Intel Socket 775, a socket that supports a wide range of motherboards. The platform memory controller accepts DDR1, DDR2, and DDR3 memory, all in a dual-channel bus configuration, which gives builders flexibility in choosing memory generations. ECC memory is not supported, so the chip targets consumer desktop builds rather than error-correcting workstation or server environments. The processor exposes PCIe Gen 2 for expansion, and integrated graphics are available only as a chipset feature on certain motherboards — meaning the CPU itself does not contain a graphics die, but a motherboard chipset can provide display output.

The multiplier is locked, so the base clock of 3.80 GHz cannot be adjusted upward through multiplier changes. The part number is SL8Q9. Production status is end-of-life, and the release date is 2005-11-13. The upgrade path for a Socket 775 system depends on motherboard compatibility; because the socket hosted many processor generations, a user could theoretically move to a different Socket 775 chip, but the end-of-life status means no new processors are being manufactured for this platform. The 90 nm process node and 169 million transistors on a 109 mm² die define the physical implementation.

Single-Thread vs Multi-Thread Behavior

The most striking structural feature of the Pentium 4 HT 672 is the asymmetry between its core count and thread count: 1 core and 2 threads. The "HT" in the product name, combined with the thread count of 2, indicates that the processor presents two logical execution contexts to the operating system from a single physical core. The base clock of 3.80 GHz is fixed — there is no boost clock — so both logical threads run at the same frequency at all times. The L1 cache is 28 KB and the L2 cache is 2 MB; these caches are shared resources for the two threads.

For single-threaded workloads, the entire 3.80 GHz pipeline and the full 2 MB L2 cache are available to one thread, which is the optimal scenario for this chip. For multi-threaded workloads, the two threads contend for the same execution units, meaning the throughput gain from the second thread is limited by the shared core. The 3.80 GHz clock is the sole operating frequency, and the absence of a boost clock means there is no headroom above that value, so the processor's performance is predictable and constant under load. The 2 MB L2 cache is relatively large for a single-core design, which helps mitigate the latency of main memory access in both single- and multi-thread scenarios.

How It Compares

The nearestRivals field in the database is empty, which means there are no recorded rival processors, no rival names, no rival scores, and no deltaPct values for this chip. Consequently, the database provides no basis for a percentage-based comparison against any specific competitor. The only comparative anchor is the percentileVsAllCpus value of 50, which places the Pentium 4 HT 672 at the median of the entire CPU population in the database. This is a positional statement, not a performance delta.

What can be said from the structural data is that the processor's competitive posture is defined by its clock speed and platform features rather than by core count. With one core and two threads, it belongs to a frequency-driven design. The 84 W TDP and 90 nm process place it in a specific power/performance class. Because the database records no rival entries, any attempt to position the chip against a named alternative would require external data, which is outside the scope of this analysis. The 50th percentile ranking is the single comparative data point available, and it indicates a median standing among all CPUs tracked.

Power and Thermals

The Pentium 4 HT 672 has a TDP of 84 W, which defines its thermal design power — the maximum amount of heat the cooling system must dissipate under sustained load. This TDP class typically requires a capable air cooler; the exact cooler size is not specified in the database, but an 84 W envelope is within the range of standard air cooling. The processor is fabricated on a 90 nm process and contains 169 million transistors on a die size of 109 mm². The combination of a 3.80 GHz clock and 84 W TDP implies a specific power density that the 90 nm process must accommodate.

Because there is no boost clock, the processor does not have a transient higher-power state; it operates at a constant 3.80 GHz, so the thermal load is steady rather than bursty. The 84 W figure is the only power-related number in the database, and it serves as the basis for cooling recommendations. The 109 mm² die size and 169 million transistor count provide context for the physical implementation, but the thermal solution should be sized to the 84 W TDP. For a desktop system, this means a mid-range cooler with adequate airflow is sufficient; no exotic cooling is implied by the data.
