About Intel Celeron G1620
The Intel Celeron G1620 is a 2-core, 2-thread desktop processor built on the Ivy Bridge architecture, released in 2012. Benchmark data places it at the 7th percentile of all CPUs in the database, with an average benchmark score of 462, underscoring its entry-level positioning for basic computing tasks.
Benchmark Performance
Benchmark results indicate that the G1620 delivers exceptionally low raw scores across all tested workloads. In Cinebench R23, it scores 1345 in the multi-core test and 189 in the single-core test. The Cinebench R20 results show 564 multi-core and 79 single-core, while the older Cinebench R15 multi-core test yields a score of 135. These figures place the processor firmly in the bottom tier of the database, as reflected by its 7th percentile ranking.
When measured against its nearest rivals, the G1620 is the slowest of the group. The data shows it trails the AMD Phenom II X3 710, which averages 463, by 0.3%. It is 0.5% behind the Intel Core i5-3339Y, which averages 464. The gap widens slightly against the AMD Athlon II X3 425, averaging 465, where the G1620 is 0.6% slower. The largest deficit is against the Intel Celeron G1820T, averaging 467, where the G1620 trails by 1.1%. While these percentage deltas are minimal, the consistency of the results shows that the G1620 sits at the very bottom of its immediate competitive cluster. The average benchmark score of 462, combined with the 7th percentile rank, confirms that this chip is designed for minimal computational demands rather than performance-oriented tasks.
Who Should Consider It
The 2-core, 2-thread configuration and low benchmark scores dictate that the G1620 is suitable only for basic office productivity, such as word processing, spreadsheet management, and light web browsing. The integrated Intel HD graphics provide a built-in display solution, eliminating the need for a discrete graphics card in simple desktop builds. This processor is not suited for modern gaming or content creation; the multi-core scores of 1345 in R23 and 564 in R20 are far too low to handle contemporary software that relies on multiple threads. The single-core scores of 189 in R23 and 79 in R20 further limit its ability to run even moderately demanding applications smoothly. For users seeking a chip for legacy system repairs, a secondary office machine, or a basic home computer where performance is not a priority, the G1620 fits the profile. However, any workload involving video editing, 3D rendering, or modern game engines will be severely constrained by the 2-thread limitation and the low absolute performance across all benchmarks.
Power and Thermals
The G1620 has a TDP of 55 watts, placing it in a low-power class that demands minimal cooling. A basic air cooler is entirely sufficient to manage the thermal output of this processor, as the 55-watt envelope does not generate significant heat. The 22 nm process node and the 94 mm² die size contribute to this modest power profile. The data indicates that power consumption and thermal management are non-issues for this chip, making it an easy component to integrate into compact or standard desktop chassis without specialized cooling solutions. The low TDP also suggests that the G1620 will run quietly and efficiently under typical office workloads, though its performance ceiling remains low.
Platform and Compatibility
The G1620 utilizes the Intel Socket 1155 interface, which dictates the compatible motherboard ecosystem. Memory support is limited to DDR3 in a dual-channel configuration, and ECC memory is not supported, restricting its use in error-sensitive server or workstation environments. The CPU provides PCIe Gen 3 with 16 lanes, allowing for the installation of a discrete graphics card or other expansion cards, though the processor's low performance would bottleneck any modern high-end GPU. Released in 2012, this chip is tied to the platform of its era. The upgrade path is confined to other Socket 1155 processors, meaning users are limited to the CPU options available for that socket generation. The lack of ECC support and the older memory standard further define this as a strictly consumer-oriented, basic desktop part.

Single-Thread vs Multi-Thread Behavior
The benchmark data reveals a distinct split between single-thread and multi-thread performance. In Cinebench R20, the single-core score is 79, while the multi-core score is 564. Similarly, in Cinebench R23, the single-core score is 189, and the multi-core score is 1345. The multi-thread scores are considerably higher than the single-thread scores, reflecting the presence of two physical cores that can handle parallel workloads. However, the absolute values for both metrics remain at the bottom of the database. This behavior indicates that the G1620 will show some improvement in multi-threaded applications compared to single-threaded ones, but the overall performance ceiling is so low that even the multi-threaded gains do not boost it out of the entry-level segment. For real-world tasks, this means the processor will struggle with any application that is heavily dependent on a single core, such as older games or certain productivity tools, while multi-threaded tasks like basic file compression will see a moderate relative improvement, though still insufficient for demanding software.
How It Compares
The AMD Phenom II X3 710 is the closest rival, with an average score of 463. The G1620 trails this processor by 0.3%, making the performance difference negligible in practical terms. Both chips occupy the same fundamental performance tier.
The Intel Core i5-3339Y averages 464, and the G1620 trails it by 0.5%. This margin is also minimal, indicating that the two processors deliver nearly identical average benchmark results despite their architectural differences.
The AMD Athlon II X3 425 averages 465, and the G1620 trails it by 0.6%. The slightly larger delta still represents a very narrow gap, keeping both chips in the same entry-level category.
The Intel Celeron G1820T averages 467, and the G1620 trails it by 1.1%. This is the largest deficit among the listed rivals, yet the absolute difference of 5 points in average score is still small. The data consistently shows the G1620 as the slowest of its immediate peers, though all five processors are clustered closely together at the bottom of the performance spectrum.
