About Intel Celeron G1620T
The Intel Celeron G1620T is a dual-core desktop processor from the Ivy Bridge generation, built on Intel's 22 nm process. It is designed for basic computing tasks, with benchmark data indicating a 7th percentile ranking among all CPUs, meaning it outperforms only a small fraction of the processors tracked in this database. Its average benchmark score of 448 places it in direct competition with several older AMD and Intel parts, making it a strictly entry-level option for systems where heavy lifting is not required.
Who Should Consider It
This processor is suitable for straightforward, single-tasking office work, web browsing, and light document editing. The Cinebench R23 multi-core score of 1302 and single-core score of 183 indicate that it can handle basic productivity applications without significant lag, but it will struggle with any modern multitasking or content creation workload. Users who primarily run a word processor, spreadsheet, or email client will find it adequate, provided they keep expectations low.
Gamers should avoid this chip for anything beyond legacy 2D titles or very old 3D games. The Cinebench R15 multi-core score of 131 is exceptionally low by current standards, and the integrated Intel HD graphics offer no meaningful gaming capability. For hardware enthusiasts building a retro PC or a low-power file server, the dual-core design and modest clock speed of 2.40 GHz are acceptable, but for any modern gaming or video streaming workload, this processor will be a bottleneck.
Content creators and video editors have no reason to consider this part. The Cinebench R20 multi-core score of 546 and single-core score of 76 demonstrate that rendering or encoding tasks will take an extremely long time. The 2 MB of shared L3 cache and lack of boost clock further limit its ability to handle bursty workloads. In short, this is a chip for basic web kiosks, lightweight office terminals, or embedded-style desktop builds where cost and power draw are the only priorities.
Power and Thermals
With a TDP of 35 watts, the G1620T sits in the low-power class of desktop processors. This rating implies that a stock cooler with a small aluminum fin stack and a modest 80-92 mm fan is entirely sufficient for thermal management. The 22 nm process node helps keep heat generation low, and the lack of a boost clock means power draw remains constant under load rather than spiking.
The 35 W TDP also means that this processor is well-suited for small form factor cases or systems with limited airflow. A passive cooler or a low-profile active cooler would likely be enough for most use cases, given the low core count and clock speed. However, the integrated Intel HD graphics will add some heat under sustained GPU load, so a basic chassis fan is recommended for system stability.
For builders targeting silent operation, this chip is a strong candidate because its thermal output is minimal. The 94 mm² die size is small, and the dual-core design limits the maximum heat density. In practice, any cooler rated for a 65 W TDP or higher will run this processor at near-ambient temperatures, though the data does not specify any particular cooler model or noise level.
Benchmark Performance
The benchmark results place the G1620T in a very narrow performance band alongside several older AMD and Intel rivals. Its average benchmark score of 448 is nearly identical to the AMD A10-5745M (449, a delta of -0.1%), meaning the two perform within statistical noise of each other. The same holds for the AMD A4-5300B (449, -0.2%) and the AMD A6-5400K (447, 0.2%), all of which are effectively tied in overall performance.
The Intel Core i3-540 is the closest rival in name, with an average score of 451, which is 0.7% higher than the G1620T. This delta is negligible in real-world terms, but it does indicate that even a first-generation Core i3 from several years earlier holds a slight edge. In multi-core workloads, the G1620T's dual-core, dual-thread configuration produces a Cinebench R23 score of 1302, while its single-core score of 183 shows that per-thread performance is extremely limited.
The Cinebench R20 results paint a similar picture: a multi-core score of 546 and a single-core score of 76. These numbers are roughly one-tenth of what a modern mid-range desktop processor would achieve, confirming that this part is only viable for the lightest tasks. The 7th percentile ranking across all CPUs underscores that the G1620T is at the very bottom of the performance spectrum, with virtually no headroom for demanding software.
Platform and Compatibility
The G1620T uses the Intel Socket 1155 platform, which is associated with the Ivy Bridge architecture and is now several generations old. The processor supports DDR3 memory in a dual-channel configuration, though the lack of an ECC option means it is not suited for error-correcting workstation builds. The PCIe interface is Gen 3 with 16 lanes available from the CPU, which is adequate for a single discrete graphics card, though the processor's low performance will likely bottleneck any modern GPU.
The 2 MB shared L3 cache and 64 KB L1 / 256 KB L2 per core are minimal by today's standards, but they are consistent with the Celeron lineup's entry-level positioning. The integrated Intel HD graphics provide basic display output, but they are not designed for gaming or hardware acceleration of modern video codecs. The 22 nm process node and 94 mm² die size are typical for this era of Intel parts.
Upgrade potential on Socket 1155 is limited to other Ivy Bridge or Sandy Bridge processors, but the motherboard chipset and BIOS will dictate compatibility. Users who own a Socket 1155 board and want a low-power drop-in replacement for a basic system could consider this chip, but there is no forward upgrade path to newer architectures. The memory bus is dual-channel DDR3, so users must have compatible DDR3 modules, and the lack of ECC support restricts use in servers or mission-critical environments.
How It Compares
AMD A10-5745M: The G1620T's average score of 448 is 0.1% lower than the A10-5745M's 449, making them effectively identical in overall performance. The A10 is a mobile part, so the comparison is somewhat academic, but the data shows no meaningful advantage for either chip. In sustained workloads, the G1620T's desktop design may offer better thermal headroom, but benchmark scores do not reflect this.
AMD A4-5300B: With an average score of 449, the A4-5300B edges out the G1620T by 0.2%. This is a negligible margin, and both processors will deliver similar experiences in everyday tasks. The A4-5300B also features integrated graphics, though the G1620T's Intel HD solution may have better driver support in legacy operating systems.
AMD A6-5400K: The A6-5400K scores 447, which is 0.2% lower than the G1620T, putting the Intel part slightly ahead. This delta is also within noise, and the two chips are interchangeable for basic workloads. The A6-5400K has an unlocked multiplier on some variants, but the G1620T's multiplier is locked, which limits overclocking potential.
Intel Core i3-540: The i3-540 posts an average score of 451, which is 0.7% higher than the G1620T. This is the largest delta among the nearest rivals, but it is still a tiny margin. The i3-540 supports Hyper-Threading, which gives it four threads versus the G1620T's two, likely explaining the slightly higher score. For users choosing between these two on the used market, the i3-540 offers a small performance edge.
