Intel Celeron 2.80

The Intel Celeron 2.80 is a desktop processor released on 2003-11-02, built on the NetBurst architecture with the Northwood codename. It occupies the 50th percentile in the database's CPU rankings, placing it exactly at the median of all tracked processors. The part carries the SL77T part number and has been marked end-of-life. With a single core, a single thread, and a fixed 2.80 GHz base clock, this processor represents a specific point in Intel's desktop lineup from the early 2000s.

Benchmark Performance

The benchmark data for the Intel Celeron 2.80 shows an average benchmark score of 0, with no individual benchmark entries recorded in the database. This absence of measured scores means the processor's performance must be assessed through its architectural characteristics and its percentile ranking rather than through direct comparative benchmarks.

The 50th percentile placement is notable — it indicates that half of all CPUs in the database rank below this processor and half rank above it. For a single-core, single-thread desktop part, this median position reflects the processor's standing across the full range of CPUs in the database, which includes processors from many generations and market segments. The 2.80 GHz base clock is the sole frequency specification; no boost clock is available, so the processor operates at a fixed 2.80 GHz under all conditions.

The cache configuration consists of an 8 KB L1 cache and a 128 KB L2 cache. These are small cache sizes, and the 128 KB L2 cache in particular limits the processor's ability to keep frequently accessed data close to the execution core. The NetBurst architecture and the 2.80 GHz clock speed define the processor's execution characteristics. The single core and single thread mean that the processor can only execute one instruction stream at a time, which fundamentally shapes its performance profile.

The 55 million transistors on a 146 mm² die, fabricated on a 130 nm process, indicate the processor's physical complexity. The 146 mm² die size is a substantial area for a 55 million-transistor design, and the 130 nm process node was the manufacturing technology for this generation of Intel processors. These physical characteristics, combined with the clock speed, determine the processor's overall performance envelope.

Power and Thermals

The Intel Celeron 2.80 carries a TDP of 73 watts. This thermal design power figure places the processor in a moderate power consumption class. A 73 W TDP requires a capable air cooler — the kind of cooling solution appropriate for a processor with this thermal load. The 130 nm manufacturing process, combined with the 55 million transistors, produces this thermal output at the 2.80 GHz operating frequency.

The processor's thermal output is a direct consequence of the clock speed and the architectural design. For system builders, the 73 W TDP implies that a standard desktop cooling solution with a heatsink and fan is sufficient, but the cooling must be properly mounted and have adequate airflow. The end-of-life production status means that thermal solutions designed for this socket are no longer manufactured, so users relying on this processor must source cooling from existing inventory or aftermarket options.

The 146 mm² die size contributes to the thermal characteristics — a larger die spreads heat over a greater surface area, which can aid in heat dissipation. The absence of integrated graphics on the processor itself means that the thermal load is entirely from the CPU core; any graphics functionality is provided by the chipset on certain motherboards, as noted in the data. This separation of graphics and CPU thermal loads simplifies the cooling requirement for the processor itself.

How It Compares

The database does not list any nearest rivals for the Intel Celeron 2.80, and the benchmark array is empty. This absence of comparative data means that a direct rival-by-rival analysis is not possible from the available information. However, the 50th percentile ranking provides a positional reference: the processor sits exactly in the middle of the database's CPU distribution.

Given the single-core, single-thread configuration and the 2.80 GHz clock, the processor is positioned among other single-core desktop parts. The NetBurst architecture and Northwood codename identify it as part of Intel's NetBurst family, and the Celeron branding indicates a desktop-market positioning. The 128 KB L2 cache is the processor's primary cache, and its size directly influences performance in memory-intensive workloads.

The 50th percentile is a meaningful data point. It suggests that, across the entire database of CPUs, this processor outperforms half of the entries. Given that the database includes a wide range of processors from different eras, this median position is consistent with a mid-range desktop part from its generation. The average benchmark score of 0, however, complicates the interpretation — without actual benchmark measurements, the percentile may reflect the processor's specifications rather than its measured performance.

Platform and Compatibility

The Intel Celeron 2.80 uses the Intel Socket 478 interface. This socket was used for Intel desktop processors in the early 2000s, and it supports a range of processors from that era. Memory support includes both DDR1 and DDR2, giving system builders flexibility in choosing memory modules. The data does not specify a memory bus width or bandwidth figure, so the memory performance cannot be quantified here. ECC memory is not supported, which limits the processor to consumer desktop applications rather than server or workstation use.

The integrated graphics functionality is provided on certain motherboards as a chipset feature, not on the processor itself. This means that the Celeron 2.80 requires a motherboard with this chipset feature or a discrete graphics card to produce a display output. The processor was released on 2003-11-02 and is now end-of-life, meaning Intel no longer produces or supports it. The part number SL77T identifies the specific stepping and packaging of this processor.

The upgrade path for Socket 478 is limited to other processors in the same socket family. Given that the Celeron 2.80 is a single-core part, users seeking more performance would need to move to a different platform entirely. The 130 nm process and NetBurst architecture are specific to this era of Intel processors, and the data does not list a PCIe specification for this processor. The multiplier is locked, so overclocking through frequency multiplier adjustment is not available.

Who Should Consider It

The Intel Celeron 2.80 is positioned for basic desktop computing tasks. Its 50th percentile ranking and single-core, single-thread design make it suitable for workloads that do not require multi-threaded execution. Office applications, word processing, spreadsheet work, and web browsing on early-2000s websites would be within the processor's capabilities. The 2.80 GHz clock speed provides responsiveness for these tasks, and the 128 KB L2 cache is sufficient for small working sets.

For gaming, the processor would be limited to titles from its release era. The single core and single thread mean that workloads requiring multiple cores would not run adequately. The absence of integrated graphics on the processor itself means that gaming performance would depend entirely on the motherboard's chipset feature or a discrete graphics card. The 73 W TDP and Socket 478 platform are both from a previous era, so building a new system around this processor is not practical; it would only be relevant for retro computing or for maintaining legacy systems.

Content creation workloads, such as video editing or 3D rendering, are not suitable for this processor. These workloads require multiple threads and would overwhelm a single-core, single-thread part. The 8 KB L1 and 128 KB L2 caches would also be a limiting factor for large datasets. The processor's 0 average benchmark score, while reflecting the absence of measured data, does not suggest strong performance in demanding applications.

Single-Thread vs Multi-Thread Behavior

The Intel Celeron 2.80 has 1 core and 1 thread, meaning it cannot execute multiple instruction streams concurrently. This is a purely single-threaded processor. All workloads, regardless of their parallelization potential, are serialized through the single execution core.

The single-thread performance is determined by the 2.80 GHz base clock and the NetBurst architecture. The 128 KB L2 cache is the primary data cache for the single core, and its size directly impacts how much data can be held close to the execution unit. For workloads that are inherently single-threaded — such as legacy applications and older games — the Celeron 2.80's fixed 2.80 GHz clock provides predictable performance. The lack of a boost clock means the processor always operates at its maximum frequency, with no dynamic frequency scaling to adjust to workload demands.

The multi-thread behavior is limited for this processor. With 1 thread, there is no thread-level parallelism. Operating systems can still time-slice between multiple processes, but each process receives a fraction of the single thread's execution time. This means that multitasking — running multiple applications simultaneously — would result in noticeable performance degradation as the single thread is shared. The 50th percentile ranking reflects the processor's overall standing in the database, but for multi-threaded workloads, this processor would rank lower, as the database's percentile accounts for the full spectrum of CPU capabilities across all tracked processors.
