Intel Celeron 1000A

The Intel Celeron 1000A is a single-core, single-thread desktop processor built on Intel’s P6 architecture, specifically the Tualatin core, and fabricated on a 130 nm process with 44 million transistors and an 80 mm² die size. It targets the Socket 370 platform, carries a 28 W TDP, and features 32 KB of L1 cache and 256 KB of L2 cache, with no L3 or vCache3d. Its production status is end-of-life, it has a launch MSRP of $69, and it occupies the 50th percentile among all CPUs in the database, though its average benchmark score is zero and no nearest rivals are listed.

Single-Thread vs Multi-Thread Behavior

The Celeron 1000A has exactly 1 core and 1 thread, which means it executes a single instruction stream with no simultaneous multithreading or parallel task splitting. Its base clock is 1000.00 MHz, with no boost clock available, so every workload runs at that fixed frequency regardless of thermal headroom or power state. This design makes the chip inherently single-thread-bound; any modern operating system or application that expects multi-core scheduling will see only one logical processor, forcing background tasks to contend with foreground applications for the same execution resources.

In real workloads, the single-thread vs multi-thread split is stark. Single-threaded tasks—such as legacy office documents, simple web browsing with one tab, or spreadsheet calculations that are not parallelized—will run at the full 1000.00 MHz capability. However, any multi-threaded workload, from video encoding to compiling code to running a virtual machine, will see zero benefit from additional threads because none exist. The data shows that the processor’s thread count equals its core count (1:1), so there is no hyper-threading trick to extract extra parallelism from a single physical core.

The lack of a boost clock further reinforces this behavior: the chip cannot transiently increase its frequency for a burst of single-thread work, nor can it lower it for power savings beyond its fixed TDP class. In practice, this means the Celeron 1000A is suited only for the simplest, most serial tasks. Multi-threaded performance is effectively capped by the single core’s arithmetic throughput, and the 50th percentile ranking suggests it sits exactly in the middle of the database’s CPU distribution—but that percentile is based on aggregate scores, not a breakdown of single vs multi-thread results. Because the benchmark list is empty, the data cannot quantify how far it falls behind a dual-core or quad-core part in parallel workloads, but structurally, a 1-core/1-thread chip cannot scale with thread count.

Power and Thermals

The TDP is rated at 28 W, which places the Celeron 1000A in a low-power class for its era, but not ultra-low. This 28 W figure is the thermal design power, meaning a cooling solution must dissipate at least that much heat under sustained load. For a Socket 370 motherboard, this implies a modest cooling tier: a small aluminum heatsink with a 40-60 mm fan, or even a passive cooler in a well-ventilated chassis, would suffice. The 130 nm process node and 44 million transistors contribute to a die size of 80 mm², which helps spread heat across a larger area, reducing hotspot density compared to a smaller die.

The absence of a boost clock means power draw stays near constant at 28 W during full load, with no transient spikes from frequency ramping. Idle power is not specified in the data, but the fixed clock suggests the chip does not dynamically scale frequency, so it likely draws close to TDP even when not fully utilized—though this is an inference from the lack of boost capability, not a measured figure. The 28 W TDP also implies that motherboard VRM requirements are minimal; a basic 2-phase power delivery on a Socket 370 board is adequate. For thermal solutions, the data does not list a cooler size or wattage, but the 28 W class is commonly handled by a low-profile cooler, not a tower or liquid solution. In a passive or low-airflow environment, the 80 mm² die and 28 W dissipation would require a heatsink with reasonable surface area, but no extreme cooling is warranted.

Benchmark results do not include thermal throttling data, so there is no evidence of sustained-load frequency drops. However, since the base clock is fixed at 1000.00 MHz and there is no boost, throttling would only occur if the cooler fails to handle 28 W, which would cause the chip to shut down rather than downclock. The 28 W TDP is thus a strict ceiling for cooling design—any cooler rated for that thermal load will keep the processor within spec.

How It Compares

The nearest rivals list is empty, so there are no direct competitors to compare against. This absence in the data means the Celeron 1000A cannot be positioned relative to other CPUs in the database using deltaPct values or rival names. The percentileVsAllCpus of 50 indicates it is exactly median among all CPUs tracked, but without rival entries, the benchmark scores and performance deltas are undefined. In qualitative terms, the chip’s single core and 1000.00 MHz clock place it below any dual-core or higher-clocked part, but no specific rival name or score is available to cite. The data shows no nearestRivals array, so any comparison would require outside information, which is not permitted. Consequently, this section cannot list rival-specific paragraphs because the FACT PACK provides no rival names, scores, or deltaPct values to analyze.

FAQ

Q: What is the core and thread count of the Intel Celeron 1000A?

A: It has 1 core and 1 thread, meaning it can process exactly one instruction stream at a time with no parallel execution.

Q: Does the Celeron 1000A have a boost clock?

A: No. The base clock is 1000.00 MHz, and the boostClock field is null, so the processor runs at a fixed frequency without dynamic overclocking.

Q: What is the TDP and what cooling does it imply?

A: The TDP is 28 W. This implies a low-power cooling tier—a basic heatsink with a small fan or a passive solution in a ventilated case—since the chip does not generate high heat loads.

Q: What cache does the processor include?

A: It has 32 KB of L1 cache and 256 KB of L2 cache. There is no L3 cache and no vCache3d.

Q: Is the memory support known?

A: Memory support is listed as “unknown” and depends on the motherboard. The memory bus is single-channel, and ECC memory is not supported.

Q: What is the launch MSRP?

A: The launch MSRP is $69.

Q: Does the chip have integrated graphics?

A: Integrated graphics are available only on certain motherboards as a chipset feature, not as a built-in GPU on the processor itself.

Q: What socket does it use?

A: It uses Intel Socket 370.

Q: Is the multiplier unlocked?

A: No, the multiplier is locked, so the user cannot adjust the clock multiplier for overclocking.

Benchmark Performance

The benchmark data for the Celeron 1000A is empty—the benchmarks array contains no entries, and the avgBenchmarkScore is 0. The percentileVsAllCpus is 50, which indicates that the processor sits at the median of all CPUs in the database, meaning half of tracked CPUs score higher and half score lower. However, since the average benchmark score is zero, this percentile likely reflects the absence of data rather than a genuine performance measurement; a score of zero is not a real benchmark result but a placeholder for untested hardware. The nearestRivals list is empty, so there are no deltaPct values to quote, and no rival names to compare against.

Because no scores exist, the data cannot show a percentage advantage or deficit relative to any other CPU. The only quantitative performance facts are the fixed 1000.00 MHz clock, the 1-core/1-thread configuration, and the cache sizes (32 KB L1, 256 KB L2). In geometric terms, a single core at 1000.00 MHz will deliver arithmetic throughput proportional to its clock, but without a boost, it cannot exceed that rate. The 50th percentile ranking is ambiguous—it could be based on a small sample or a weighted estimate, but the avgBenchmarkScore of 0 contradicts any meaningful performance tier. The absence of rivals means no “30% ahead of X” or “20% behind Y” statements can be made from the FACT PACK.

For a user interpreting the data, the takeaway is that the Celeron 1000A is a baseline single-core part with no measurable benchmark footprint in this database. Its 28 W TDP and fixed clock suggest it was designed for low-cost, low-performance systems—likely entry-level desktops or thin clients—where single-threaded tasks are the norm. The 130 nm process and 44 million transistors are modest by any standard, but the 256 KB L2 cache is notable for its size relative to the core count, potentially reducing memory latency for repetitive loops. Still, without benchmark scores, the performance cannot be quantified relative to any rival, and the empty nearestRivals array confirms that no competitive positioning is available in the data. The 50th percentile is the only comparative metric, and it is not supported by any actual score, so it should be treated as a placeholder rather than a verified ranking.
