Celeron G1820 Core Configuration
Processing cores and threading
The Intel Celeron G1820 features 2 physical cores and 2 threads, which directly impacts multi-threaded performance in CPU benchmarks. More cores allow the processor to handle parallel workloads efficiently, improving performance in video editing, 3D rendering, and multitasking scenarios. Thread count determines how many simultaneous tasks the CPU can process, with higher thread counts benefiting productivity applications and content creation workflows.
Celeron G1820 Clock Speeds
Base and boost frequencies
Clock speed is a critical factor in Celeron G1820 benchmark performance, measured in GHz. The base clock represents the guaranteed operating frequency, while the boost clock indicates maximum single-core performance under optimal conditions. Higher clock speeds translate to faster single-threaded performance, which is essential for gaming and applications that don't fully utilize multiple cores. The Celeron G1820 by Intel can dynamically adjust its frequency based on workload and thermal headroom.
Intel's Celeron G1820 Cache Hierarchy
L1, L2, L3 cache sizes
Cache memory is ultra-fast storage built directly into the Celeron G1820 processor die. L1 cache provides the fastest access for frequently used data, while L2 and L3 caches offer progressively larger storage with slightly higher latency. Larger cache sizes significantly improve CPU benchmark scores by reducing memory access times. The Celeron G1820's cache configuration is optimized for both gaming performance and productivity workloads, minimizing data fetch delays during intensive computations.

About Intel Celeron G1820
The Intel Celeron G1820 is a 2-core, 2-thread desktop processor built on Intel’s Haswell architecture for Intel Socket 1150. The data places it at the bottom of the CPU field: it sits in the 9th percentile of all CPUs and carries an aggregate average benchmark score of 500. With a 2.70 GHz base clock, no boost clock, and a 54 W TDP, this is a strictly entry-level dual-core part.
Benchmark Performance
Benchmark results show a consistent low-end profile. In Cinebench R23, the G1820 scores 1453 in multi-core and 205 in single-core. In Cinebench R20, it scores 610 in multi-core and 86 in single-core. The older Cinebench R15 test returns a multi-core score of 146. These are modest figures for any modern desktop workload, and they place the processor at the 9th percentile among all CPUs in the database.
The aggregate average benchmark score is 500, and the nearest rival data shows how tight this segment is. Against the AMD A4 PRO-3340B, the G1820 is 0.1% ahead with both CPUs carrying an average score of 500. Against the Intel Celeron G1630, the G1820 is 0.2% ahead on an average score of 499. The Intel Core i3-2100T sits 0.3% ahead of the G1820 with an average score of 502. The AMD Athlon II X3 440 is 0.6% ahead with an average score of 503. In other words, the G1820 is effectively tied with all four of its nearest rivals. The absolute performance level is very low, but the competitive spread at this tier is also very small, so these percentage differences will not translate into meaningful real-world gaps.
None of the Cinebench scores suggest headroom for demanding applications. The multi-core numbers are far below what high-thread-count workloads need, and the single-core numbers are likewise low. The average benchmark score of 500 confirms that this CPU clusters with other aging low-end desktop parts rather than with any modern mainstream performer.
Power and Thermals
The G1820 carries a 54 W TDP. This places it in a low-power desktop class, and the cooling requirement is correspondingly modest. A basic air cooler is sufficient for this part; the data does not indicate a need for high-end cooling hardware.
The 22 nm Haswell process, 1,400 million transistors, and 177 mm² die size are all consistent with that thermal envelope. The processor has no boost clock and a locked multiplier, so it does not have an uncontrolled high-frequency mode that would push thermals beyond its base operating state. The integrated Intel HD (Haswell) graphics also stays inside the same 54 W package-level design point. For users building a small or quiet desktop system, the G1820’s thermal behavior is not a limiting concern.
Who Should Consider It
This processor is suited to light desktop use. The 2-core, 2-thread arrangement and the 9th-percentile standing indicate that it is not intended for high-performance workloads. For basic office tasks, such as document editing, spreadsheet work, and general communication, the G1820 provides enough multi-core performance; its R23 multi-core score of 1453 and R20 multi-core score of 610 are adequate for low-demand interactive use.
For gaming, the data points in the opposite direction. The low overall percentile, low single-core scores, and integrated Intel HD (Haswell) graphics mean it is not a gaming-oriented part. The 205 R23 single-core score is far below the level associated with modern game performance. A discrete GPU would be required for even modest gaming, and the CPU itself would still be a bottleneck.
For content creation, the G1820 is not a realistic choice. Rendering, video encoding, and heavy compilation workloads scale with multi-core performance, and the G1820’s 1453 R23 multi-core score is simply too low. Users whose work demands substantial processing power should look elsewhere. The G1820’s proper role is a low-cost, low-power desktop processor for tasks that do not push the CPU hard.

Single-Thread vs Multi-Thread Behavior
The single-thread and multi-thread scores reveal a processor with a very narrow performance envelope. In Cinebench R23, the single-core score is 205 and the multi-core score is 1453. In Cinebench R20, the single-core score is 86 and the multi-core score is 610. The multi-core result is higher, but that is expected from a part with two cores; the difference reflects two cores running together rather than any high-frequency advantage.
Single-thread performance is tied to the 2.70 GHz base clock because there is no boost clock available. That means lightly threaded workloads, such as older applications or single-threaded productivity tools, will run only as fast as the base frequency and modest Haswell core design allow. The low single-core scores confirm that this is not a responsive part for demanding single-threaded tasks.
Multi-thread performance is limited by the 2-thread total. With only one thread per core, the G1820 cannot overlap additional work the way higher-thread-count parts can. The multi-core scores are therefore low in absolute terms. This split means the G1820 will feel most acceptable in workflows that are short, light, or not strongly multi-threaded. Any workload that scales to many threads will quickly expose the dual-thread ceiling.
Platform and Compatibility
The Intel Celeron G1820 is a Desktop-market processor in the Celeron (Haswell) generation. It uses Intel Socket 1150, making it compatible with motherboards designed for that socket. Memory support is DDR3 only, over a dual-channel bus, with no ECC support. Expansion connectivity is provided through PCIe Gen 3, and the integrated Intel HD (Haswell) graphics provide a display output without requiring a separate graphics card.
The processor is still listed as in active production, and its release date is 2013-11-30. The cache configuration includes 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 3 MB of shared L3 cache. The multiplier is locked, so the intended operating mode is its stock 2.70 GHz base clock. Any upgrade path is constrained by the Socket 1150 platform and DDR3 memory support; a replacement processor must be compatible with those platform characteristics.
How It Compares
Against the AMD A4 PRO-3340B, the G1820 is effectively a tie. Both have an average benchmark score of 500, and the 0.1% delta is negligible. This is the closest rival in the dataset.
Against the Intel Celeron G1630, the G1820 is 0.2% ahead. The G1630 has an average benchmark score of 499, placing the two parts at essentially the same performance level. This is another near-identical result.
Against the Intel Core i3-2100T, the G1820 sits 0.3% behind. The i3-2100T has an average benchmark score of 502. The gap is small, but it puts the G1820 at the lower end of this immediate peer group.
Against the AMD Athlon II X3 440, the G1820 trails by 0.6%. The Athlon II X3 440 has an average benchmark score of 503. This is the largest delta among the nearest rivals, yet even this difference is minimal in real-world terms.
