Intel Pentium 4 1.8A

The Intel Pentium 4 1.8A is a single-core, single-thread desktop processor from Intel, built on the NetBurst architecture with the Willamette codename and a 180 nm process. It runs at a base clock of 1800.00 MHz, has no recorded boost clock, and is installed on Intel Socket 478. The fact pack contains no benchmark entries and no nearest rivals, so the following analysis is limited to the architectural and platform fields that are present.

Who Should Consider It

The fact pack does not include any gaming, creation, or office benchmark scores. The benchmarks array is empty, the average benchmark score is 0, and the nearestRivals array is empty. That means there is no measured workload evidence to support a recommendation for modern gaming, content creation, or office productivity. Instead, the workload profile has to be read from the specifications: it is a 1-core, 1-thread processor with no boost clock, so the only execution resource is a single thread at 1800.00 MHz.

For users building a legacy desktop system, the relevant facts are the Intel Socket 478 platform, the NetBurst architecture, the Willamette codename, and the Pentium 4 (Willamette) generation label. The processor draws 69 W TDP and was released on July 1, 2001, which places it in an early Pentium 4 context. The cache hierarchy is small by later standards: 8 KB of L1 cache, 256 KB of L2 cache, and no L3 cache recorded. A user who needs more than one thread will find no support in the data, because the core count and thread count are both exactly 1.

The integrated graphics field reads "On certain motherboards (Chipset feature)", so display capability is not a guaranteed processor feature. A user who needs graphics without a separate card would have to rely on a motherboard whose chipset provides that feature. No PCIe information is recorded, so any decision involving modern expansion cards cannot be grounded in this fact pack. The production status is end-of-life, and the market segment is desktop. In short, the data supports a narrow audience: those specifically interested in this legacy Socket 478 NetBurst processor, not users needing measured performance for current workloads.

Single-Thread vs Multi-Thread Behavior

The single-thread versus multi-thread split is straightforward here because there is no multi-thread capability in the data. The processor has 1 core and 1 thread, so it can handle exactly one thread at a time. The boost clock field is null, meaning the fact pack records no boost frequency; the operational clock is the base clock of 1800.00 MHz. There is no additional thread resource to absorb parallel work.

For real workloads, this means that any software relying on multi-threading has no parallel execution path on this processor. Single-threaded software has access to the full 1800.00 MHz base clock and the recorded cache levels: 8 KB L1 and 256 KB L2. Because no benchmark scores are present, the actual performance effect of this clock and cache combination cannot be quantified from the data. What the data does show is a processor with no boost clock, no additional threads, and no L3 cache. In workload terms, the distinction between single-thread and multi-thread behavior is therefore asymmetrical: single-thread is the only supported path, and multi-thread workloads cannot be accelerated by additional cores or threads.

How It Compares

The fact pack's nearestRivals array is empty, so there are no rival names, no rival scores, and no deltaPct values to report. This processor cannot be positioned against any specific competitive CPU using the provided data. The only relative reference points are the percentileVsAllCpus value of 50 and the average benchmark score of 0. With no benchmark entries, that 50th-percentile rank has no supporting workload scores behind it. Consequently, no comparative percentage deltas can be stated, and no rival-by-rival comparison paragraphs are possible from this fact pack.

FAQ

Q: How many cores and threads does the Intel Pentium 4 1.8A have?

A: It has 1 core and 1 thread, so it executes a single thread at a time.

Q: What clock speeds are recorded for this processor?

A: The base clock is 1800.00 MHz, and the boost clock field is null, so no boost speed is recorded.

Q: What socket does this processor use?

A: It uses Intel Socket 478.

Q: Does the processor support ECC memory?

A: The ECC memory field is false, so ECC memory support is not indicated in the fact pack.

Q: Does it have integrated graphics?

A: The integrated graphics field says "On certain motherboards (Chipset feature)", meaning graphics depend on a motherboard chipset feature rather than being a guaranteed processor capability.

Q: Is the multiplier unlocked?

A: No; multiplierUnlocked is false.

Q: What cache sizes are recorded?

A: The L1 cache is 8 KB, the L2 cache is 256 KB, and L3 is null.

Power and Thermals

The TDP for the Intel Pentium 4 1.8A is 69 W. That is the only power figure in the fact pack. Because the boost clock is null, thermal behavior is tied to a single recorded clock speed: 1800.00 MHz. The processor is built on a 180 nm process and contains 42 million transistors on a 217 mm² die, which provides the manufacturing context for the 69 W TDP. The data does not include a specific cooler or cooling class, so the exact tier of cooler cannot be stated from this page. What can be stated is that any cooling solution must be matched to a 69 W TDP and a processor with no boost clock. The production status is end-of-life, and no cooling bundle or thermal solution is listed in the fact pack.

Platform and Compatibility

The platform anchor for this processor is Intel Socket 478. The fact pack records no memory support information, no memory bus width, and no memory bandwidth, so no memory type or channel claim can be made. ECC memory is marked false, indicating no ECC support. PCIe information is null, so no PCIe version or lane configuration is available. Integrated graphics are described as "On certain motherboards (Chipset feature)", which means the motherboard chipset determines whether graphics are available. The processor is not multiplier unlocked, so multiplier adjustment is not part of its feature set. The part number is SL63X. The release date is July 1, 2001, and the production status is end-of-life. Because the fact pack lists no other Socket 478 processors and no motherboard compatibility list, an upgrade path cannot be established from the available data.

Benchmark Performance

The average benchmark score is 0, and the benchmarks array is empty. There are no per-workload scores, no gaming scores, no creation scores, and no office scores. The nearestRivals array is empty, so there are no exact deltaPct values against any rival. The only numerical positioning in the fact pack is percentileVsAllCpus = 50, which places the processor at the 50th percentile of all CPUs in the database. Without actual benchmark entries, that percentile cannot be decomposed into single-thread or multi-thread performance. Therefore, the benchmark performance section is limited to the data available: no rival deltas, no scores, and an average benchmark score of 0.
