Celeron G1820 Details

The Intel Celeron G1820, launched in December 2013, stands as a legacy desktop processor from Intel's Haswell generation, built on a 22 nm process. With a base clock of 2.7 GHz and a turbo frequency of 2.48 GHz, it features two cores and two threads, lacking simultaneous multithreading. Despite its age, it remains relevant for entry-level computing tasks due to its integrated Intel HD (Haswell) graphics, which supports up to three displays and operates at a base frequency of 350 MHz with a burst frequency of 1.05 GHz. The processor operates within a 53 W TDP and is compatible with the FCLGA1150 socket, supporting DDR3-1333 memory across a dual-channel interface with a maximum capacity of 32 GB.

In terms of cache, the G1820 includes 61 KiB of L1 cache, 244 KiB of L2 cache, and a substantial 2.86 MiB of L3 cache, which helps mitigate latency in memory access. It supports PCIe 3.0 with up to 16 lanes and includes a range of instruction set extensions such as AVX2, FMA3, AES-NI, and virtualization technologies like VT-x and VT-d. The processor also features EIST for power efficiency and is locked, limiting overclocking potential.

Benchmark results place the Celeron G1820 at an Overall Score of 4458, ranking it #1326 out of 2060 processors. Its Singlecore Score of 4517 positions it at #1275, while its Multicore Score of 4369 ranks it #1534. These scores indicate that while the G1820 holds its own in single-threaded workloads—outperforming several older and modern low-end CPUs—it lags significantly in multi-threaded performance, especially when compared to contemporary processors. Its strongest performance category is single-core, where it competes with early-generation Core i3 and i5 models.

As of March 2026, the Celeron G1820 is best suited for basic office use, web browsing, and light multimedia tasks. While it lacks the power for gaming or content creation, its low TDP and integrated graphics make it an energy-efficient choice for budget desktops or secondary systems. Its position in the competitive landscape highlights its role as a cost-effective, no-frills processor rather than a performance-oriented solution.
