Celeron G5900

The Celeron G5900 is a 2-core / 2-thread processor based on the Comet Lake (2020−2025) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 3.4 GHz from a base frequency of 3.4 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 2 MB (total) of L3 cache, plus 256K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 2,682, placing it in the Entry Level performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 850, while multi-core reaches 1,600.

The Celeron G5900 fits into the LGA1200 socket and supports PCIe 3.0 with 16 total PCIe lanes for expansion cards and storage. It supports DDR4-2666 memory at speeds up to DDR4-2666 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 128 GB across 2 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers. Integrated graphics: UHD Graphics 610 — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Celeron G5900 is primarily designed for Budget. Virtualization: VT-x — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Pentium Gold G6400.

The Celeron G5900 has a rated TDP (Thermal Design Power) of 58 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately. Recommended cooling: Stock.

At an average price of $42 (MSRP: $50), the Celeron G5900 delivers 64 PassMark points per dollar. Performance ranking position: #2333 out of all indexed processors.
