Intel Pentium 4 HT Extreme Edition 3.20

The Intel Pentium 4 HT Extreme Edition 3.20 is a single-core desktop processor from Intel's NetBurst Gallatin generation, released on 2003-11-02. It occupies the 50th percentile in the benchmark database, placing it exactly at the median of all recorded CPUs. With a 3.20 GHz base clock, one physical core, and two threads via Hyper-Threading, this end-of-life part represents a transitional design: a high-clock single-core chip with a 2 MB L3 cache, aimed at the enthusiast desktop segment at a launch MSRP of $899.

Benchmark Performance

The database records no individual benchmark scores for this CPU; its average benchmark score is listed as 0. The only quantitative performance anchor is the percentile rank: 50th among all CPUs in the database. This places the Pentium 4 HT Extreme Edition 3.20 at the exact median of the distribution — it is projected to outperform roughly half of all recorded processors and fall behind the other half. Because no nearest-rival entries are supplied, there are no percentage deltas to report against specific competitors. The data does not support claims of being ahead of or behind any named part by a specific margin. Instead, the 50th percentile should be read as a statement of central tendency: this is a middle-of-the-pack desktop CPU in the database's aggregate view, not a top-tier or bottom-tier performer.

The absence of recorded benchmark scores is itself informative. With an average score of zero, the database treats this part as unmeasured rather than as a strong or weak performer. The 50th percentile is therefore a positional statement, not a measured result. For a processor with a 3.20 GHz clock, one core, and two threads, the expectation is that single-threaded workloads will be the primary strength, while multi-threaded scaling is limited to two logical processors. The benchmark percentile reflects the entire CPU population, which includes modern multi-core parts; sitting at the midpoint suggests that this 2003-era chip holds its own only in the narrow context of single-threaded throughput. The data shows no boost clock, so the 3.20 GHz figure is both the sustained and maximum operating frequency, meaning performance under load is steady rather than bursty.

The 50th percentile also implies that the CPU's architectural advantages — the large 2 MB L3 cache and the high 3.20 GHz clock for its generation — are offset by its single-core limitation when measured against the full database. A processor with two threads cannot compete with modern parts that offer many physical cores, yet it does not fall to the bottom of the distribution, indicating that its clock speed and cache still provide meaningful single-threaded capability. The percentile is a static ranking; it does not distinguish between workloads, so the same 50th percentile applies to gaming, creation, and office tasks in the database's aggregate view.

How It Compares

The fact pack lists no nearest rivals for this part. Consequently, the analysis cannot provide head-to-head percentage deltas against specific competitor names. The only comparative data available is the aggregate 50th percentile. Against the "typical" CPU in the database — defined as the median performer — the Pentium 4 HT Extreme Edition 3.20 is exactly even: it neither leads nor trails the median. For a processor released in late 2003, this is a notable position, because the database's CPU population includes many later and more parallel parts. The data indicates that the Gallatin EE's high clock speed and large L3 cache compensate for its single-core design only in workloads that favor clock rate and cache capacity.

Without rival entries, any statement such as "faster than X" or "slower than Y" would be fabrication. The honest reading is that this CPU's standing is defined entirely by its median percentile. Buyers evaluating this part today would be comparing it against modern CPUs that are far outside its architectural generation, but the database does not provide the deltas to quantify that gap. The 50th percentile is the single point of comparison: it is a midpoint chip, neither a leader nor a laggard. The lack of rival data also means the database does not confirm whether the Extreme Edition branding translated into a measurable advantage over the standard Pentium 4 HT parts of its era; no such comparison is recorded.

Platform and Compatibility

The Pentium 4 HT Extreme Edition 3.20 uses Intel Socket 478. Memory support is DDR1 or DDR2, depending on the motherboard; the memory bus is dual-channel, and ECC memory is not supported. The PCIe field is null — no PCI Express specification is recorded — which means the platform predates or omits PCIe in the database's view; expansion would rely on the motherboard's chipset-provided slots. Integrated graphics are available on certain motherboards as a chipset feature, not on the CPU itself, so a discrete graphics solution is required unless the chosen motherboard includes a graphics-capable chipset. The multiplier is locked, so overclocking via multiplier adjustment is not possible; frequency adjustments would be limited to bus clock changes, which the database does not document. The part number is SL7AA.

Production status is end-of-life, with a release date of 2003-11-02. The 130 nm process node, 178 million transistors, and 269 mm² die define the physical platform. The L1 cache is 8 KB, the L2 cache is 512 KB, and the L3 cache is 2 MB. The memory controller is not integrated into the CPU; the database lists memory support as "depends on motherboard," meaning the chipset determines whether DDR1 or DDR2 is used. The dual-channel memory bus is a chipset-level feature as well. The upgrade path is limited by the Socket 478 form factor; the database does not list specific compatible successors, and the end-of-life status indicates no ongoing support or new motherboard production. The market segment is desktop, and the multiplier is locked, so this is a fixed-frequency part.

Who Should Consider It

The benchmark data places this CPU at the 50th percentile, with no measured scores. For gaming, the single 3.20 GHz core and two threads mean it is suited to era-appropriate titles that rely on high clock speed rather than multiple cores; modern games that require more than two threads will not scale. The 2 MB L3 cache helps with working sets that fit within it, but the single core is the binding constraint. For content creation, the 1-core/2-thread design limits rendering, encoding, and compilation workloads, which typically benefit from many cores; the data does not indicate strong multi-threaded performance, and the 50th percentile does not change that assessment. For office and productivity tasks that are single-threaded — document editing, spreadsheet work, web browsing of the period — the 3.20 GHz clock and 2 MB L3 cache provide adequate responsiveness.

The 50th percentile suggests it is a balanced midpoint performer, not a specialist. Enthusiasts of the NetBurst era or collectors of the Gallatin EE part number SL7AA would consider it for its historical position, particularly given the 178 million transistors and 269 mm² die that mark it as a flagship of its generation. It is end-of-life, so new system builds are not a realistic use case; the target audience is someone maintaining a legacy Socket 478 system or documenting the architecture. The locked multiplier means no overclocking headroom via multiplier, so users seeking frequency flexibility should look elsewhere. The lack of ECC support rules out error-corrected memory workloads, and the absence of a recorded PCIe specification means modern expansion cards may not be compatible.

Single-Thread vs Multi-Thread Behavior

The Pentium 4 HT Extreme Edition 3.20 has one physical core and two logical threads. Single-threaded performance is driven by the 3.20 GHz base clock and the NetBurst architecture's deep pipeline, with the 2 MB L3 cache reducing memory latency for working sets that fit. The database's 50th percentile reflects the CPU's standing across all workloads; for single-threaded tasks, the high clock is the primary asset. Multi-threaded behavior is limited to two threads via Hyper-Threading, which allows a single core to present two logical processors to the operating system. This helps with light parallelism — such as a background task alongside a foreground application — but does not double throughput. The data shows no boost clock, so the 3.20 GHz figure is the sustained and maximum clock.

Real workloads: applications that are strictly single-threaded will see the full benefit of the clock speed; applications that can use exactly two threads will see modest gains from Hyper-Threading, as the single core time-slices between the two logical processors. Anything requiring four or more threads will leave the CPU at a disadvantage relative to the median of the database, even though the percentile is 50 overall. The 8 KB L1 and 512 KB L2 caches are small by modern standards, but the 2 MB L3 cache is the standout feature, providing a larger staging area for repeated data access. The dual-channel memory bus helps feed the single core, but memory bandwidth is not quantified in the database. The single-thread vs. multi-thread split is stark: the CPU is a strong single-threaded part for its era, but its multi-threaded ceiling is two logical threads, which limits its usefulness in parallel workloads.

Power and Thermals

The TDP is 92 W. On a 130 nm process with 178 million transistors on a 269 mm² die, this TDP class requires a cooling solution capable of dissipating nearly 100 W. The data does not specify a cooler size or type, but a 92 W TDP implies a substantial air cooler with a heatsink and fan adequate for desktop use; liquid cooling is not indicated by the data. The 130 nm Gallatin die is large, and the 2 MB L3 cache contributes to the transistor count and thermal load. The processor is end-of-life, so thermal management is a concern only for existing systems or collectors. The locked multiplier means no voltage or frequency adjustments via multiplier, so thermals are defined by the stock 3.20 GHz operation. The absence of a boost clock means power draw is steady at the base clock under load, rather than spiking to a higher frequency. No integrated graphics on the CPU itself — graphics are a chipset feature on certain motherboards — so the CPU's thermal envelope is dedicated solely to the processing cores and cache. The 92 W TDP places it in a mid-range thermal class for desktop CPUs of its time; the database does not provide a comparison to other TDP values, so no relative statement can be made.
