Celeron N2805 Details

Ranked #2052 of 2060 in overall performance, the Intel Celeron N2805 stands as one of the lowest-performing processors in modern benchmarking evaluations. Its single-core score of 3198 places it just behind the Atom Z670, while its multicore score of 4256 reflects minimal parallel processing capability. Despite being released in September 2013, the Celeron N2805 remains a product of Intel's Bay Trail-M architecture, built on a 22 nm process node and designed for ultra-low-power mobile applications. With a TDP of only 4 W, it was intended for fanless systems and lightweight computing tasks, making it a rare choice for users seeking energy efficiency over raw performance.

The processor features two cores and two threads, with no support for simultaneous multithreading or ECC memory. It operates at a base clock of 1.463 GHz, with a locked multiplier that prevents overclocking. Each core includes 512 KB of L2 cache, while the L1 cache totals 0.053 MiB. Integrated into the design is Intel's HD Graphics, which supports basic multimedia playback but lacks modern GPU compute capabilities. The processor is socketed in BGA1170, a chip-on-package design typical of embedded and mobile devices, and is compatible with DDR3 memory.

Despite its age, the Celeron N2805 holds a niche role in low-cost devices such as netbooks and embedded systems. However, its benchmark scores—particularly the single-core score of 3198—highlight its limitations in handling modern software, especially applications that rely on SSE4 or other advanced instruction sets. The lack of support for SSE4 is a significant drawback for contemporary software and games, which can result in poor compatibility and performance. The processor also lacks features such as AES-NI, AVX, and virtualization support (Intel VT-x), further limiting its utility.

In the broader context of today's computing landscape, the Celeron N2805 is far outpaced by even entry-level modern CPUs. While it may still function in basic productivity tasks, its performance is dwarfed by processors like the Ryzen 5 9600X or Core i9-14900KS, which dominate the top 50 rankings in every category. Its placement near the bottom of benchmark lists underscores its role as a legacy component, suitable only for systems where power consumption and cost are prioritized over performance. As of March 2026, the Celeron N2805 remains a relic of early 2010s mobile computing, with no practical relevance in modern desktop or laptop environments.
