Intel Celeron 450

The Intel Celeron 450 is a single-core desktop processor from the Core 2 architecture, released in late August 2008. It operates at a fixed clock speed of 2.20 GHz with no boost capability, and its performance profile places it in the 50th percentile among all CPUs in the database, a median position that reflects its entry-level status during its production lifetime.

Benchmark Performance

The benchmark data for the Celeron 450 is sparse, with an average benchmark score of 0 and an empty nearestRivals array. This absence of direct scoring means that quantitative comparisons against specific competitors are not available from the database. However, the 50th percentile ranking provides a meaningful anchor: this processor sits exactly at the midpoint of all recorded CPUs, indicating that half of all processors in the database perform better and half perform worse. For a single-core, single-thread chip from 2008, this median standing is notable, as it suggests that in its era, the Celeron 450 was not an outlier at the bottom but rather a representative entry-level part.

The lack of rival deltas (no nearestRivals data) prevents any percentage-based comparisons, but the percentile figure alone tells a clear story. A processor with one core and one thread, running at 2.20 GHz, cannot compete with modern multi-core designs in raw throughput, yet its 50th percentile placement indicates that within the historical dataset, it held a middle-ground position. This is likely due to the fact that the database includes many older and lower-clocked parts, allowing the Celeron 450 to outrank the weakest entries while falling far behind high-end offerings.

Interpretation of the zero average benchmark score requires caution. It may indicate that no standardized benchmark runs were recorded for this SKU, or that the chip failed to complete tests. In either case, the percentile data remains the primary quantitative signal, and it suggests a processor that was adequate for basic tasks but never intended for demanding workloads.

Power and Thermals

The Celeron 450 carries a TDP of 35 watts, which classifies it as a low-power part for its socket generation. This figure is modest by any standard, and it implies that cooling requirements are minimal. A stock Intel cooler from the socket 775 era would be more than sufficient, and even a passive heatsink with adequate case airflow could handle this chip in many scenarios. The 35W TDP also means that system builders could pair this processor with small form factor cases or low-noise builds without thermal concerns.

The 65 nm process node contributes to this efficiency, as does the small die size of 77 mm² with 105 million transistors. These architectural choices kept power draw low while maintaining a reasonable clock speed of 2.20 GHz. For users prioritizing quiet operation or low energy consumption, the Celeron 450's thermal profile is a clear advantage, though it comes at the cost of computational performance. The data indicates that this is a chip that runs cool under load, and thermal throttling would be unlikely even with basic cooling solutions.

Who Should Consider It

Given its single-core, single-thread design and 2.20 GHz clock, the Celeron 450 is suited only for the most basic computing tasks. Office work involving word processing, spreadsheets, and email would be within its capabilities, provided the user exercises patience with multitasking. The 512 KB L2 cache and 64 KB L1 cache are small, but they are adequate for single-threaded applications that do not require large working sets.

Gaming is not a realistic use case for this processor. Modern games require multiple cores and high IPC, neither of which the Celeron 450 offers. Even older titles from its 2008 era would run poorly at best, and the lack of boost clock means there is no headroom for demanding moments. The integrated graphics option, listed as "On certain motherboards (Chipset feature)," is not a processor feature but a chipset capability, meaning the Celeron 450 itself has no iGPU. Users must pair it with a discrete graphics card, which further limits its appeal for budget gaming builds.

Content creation workloads, such as video editing or 3D rendering, are entirely out of scope for this chip. These tasks are heavily multi-threaded, and a single core cannot handle them efficiently. The benchmark percentile of 50 suggests that even in its own time, it was not a performance part but rather a budget option for basic office machines or embedded-like applications. Anyone considering this processor today would be doing so for retro computing, legacy system repair, or very light productivity, not for any performance-oriented task.

FAQ

Q: What is the clock speed of the Intel Celeron 450?

A: The base clock is 2.20 GHz, and there is no boost clock available, meaning the processor runs at a fixed frequency.

Q: How many cores and threads does this processor have?

A: It has 1 core and 1 thread, making it a single-core, single-thread part.

Q: What memory types does the Celeron 450 support?

A: It supports DDR1, DDR2, and DDR3 memory in a dual-channel configuration, though ECC memory is not supported.

Q: What is the TDP of this processor, and what cooling does it require?

A: The TDP is 35 watts, which requires only a basic air cooler; a stock cooler from the socket 775 platform is sufficient.

Q: Does this processor have integrated graphics?

A: No, the Celeron 450 does not have integrated graphics. The fact pack notes that graphics are "On certain motherboards (Chipset feature)," so a discrete GPU is required.

Q: What socket does this processor use?

A: It uses Intel Socket 775, which is an older platform that supports DDR2 and some DDR3 motherboards.

Single-Thread vs Multi-Thread Behavior

The Celeron 450's architecture is the simplest possible: one core and one thread. There is no multi-threading behavior to analyze because the processor cannot execute more than one thread at a time. This means that all workloads, regardless of their parallelism, are limited to a single execution stream. For single-threaded applications, the 2.20 GHz clock is the only performance lever, and it is a modest one by modern standards.

The implications for real workloads are straightforward. Any application that is inherently single-threaded, such as older productivity software or simple scripts, will run at the mercy of the 2.20 GHz clock. The lack of a boost clock means there is no transient performance spike to handle brief bursts of activity. Conversely, any multi-threaded workload will not benefit from additional cores, because there are none. The 50th percentile ranking reflects this balanced but limited capability: the processor is neither exceptionally fast nor exceptionally slow for its era, but its single-thread design caps its potential in any multi-tasking scenario.

The 512 KB L2 cache is also a factor in single-thread performance. Smaller caches generally mean more frequent memory accesses, which can stall the pipeline. However, for the basic tasks this chip targets, the cache size is adequate. The data shows a processor that is purely a single-thread device, and users must align their expectations accordingly.

Platform and Compatibility

The Celeron 450 uses the Intel Socket 775, a platform that was widespread in the late 2000s. This socket supports a range of chipsets, and the processor's memory support includes DDR1, DDR2, and DDR3, though not all motherboards support all three types. The dual-channel memory bus is a standard feature, and the processor does not support ECC memory, which is typical for consumer desktop parts.

PCIe Gen 2 is supported, which allows for modern graphics cards and expansion cards, though the single-core processor will bottleneck any discrete GPU in gaming scenarios. The lack of integrated graphics means a dedicated GPU is mandatory for display output, and the PCIe Gen 2 interface is sufficient for older graphics cards that were contemporary with this processor.

The upgrade path on socket 775 is limited. While the socket supports many other processors, including dual-core and quad-core parts from the Core 2 family, the Celeron 450's lineage is the Conroe-L architecture, which is an older and simpler design. Users looking to upgrade would need to check motherboard compatibility, as not all socket 775 boards support all processors. The production status is end-of-life, and the launch MSRP was $53, which reflects its budget positioning. The processor is not multiplier unlocked, so overclocking is not possible via the multiplier, though bus overclocking on compatible motherboards could theoretically be attempted, but the data does not support any such claims. The part number is SLAFZ, and the processor is manufactured by Intel on a 65 nm process with a die size of 77 mm² and 105 million transistors.
