Intel Celeron G5900 2-core LGA 1200

The Intel Celeron G5900 is a dual-core budget desktop processor that's cheap and surprisingly snappy for single tasks, but struggles with anything multi-threaded. It's a decent pick for basic office or home theater builds at USD 36 to USD 50. For anything more demanding, spend a little extra on a used i3 or Ryzen 3 instead.

The G5900 posts a PassMark multi-core score of 572, which puts it in the 20th percentile for multi-threaded performance. That's rough. For context, a modern budget chip like the Ryzen 5 5500 scores several times higher. But the single-thread story is different. The 3434 single-thread score lands in the 86th percentile, which is genuinely impressive for a chip this cheap. That means basic tasks like launching apps, loading web pages, and navigating Windows feel snappier than you'd expect from a Celeron.

In practice, the 2 cores and 2 threads are the bottleneck. Open a dozen browser tabs, a spreadsheet, and a video call at the same time, and you'll feel it choke. The 2MB of L3 cache doesn't help either. But for a single task at a time, the 3.4GHz clock speed keeps things moving. The integrated Intel UHD Graphics 610 is fine for desktop use and 1080p video playback, but don't expect it to run anything beyond the lightest of games.

The Ryzen 5 5500 is the elephant in the room here. It costs more, but it's a 6-core, 12-thread chip that absolutely demolishes the G5900 in multi-threaded workloads. If you can stretch your budget even a little, that's the smarter long-term play. The Dell Xeon E5-2637 V2 is an interesting alternative on the used market. It's older and uses a different socket, but those Xeons can be found cheap and offer more cores for server-style workloads.

Against other ultra-budget options, the G5900 holds its own in single-threaded tasks thanks to that 86th percentile score. But the be quiet! and Thermal Grizzly entries in our database are cooler products, not CPUs, so they're not really direct comparisons. If you're set on LGA 1200 and need the absolute cheapest chip that works, the G5900 is fine. Just know that a used i3-10100 or i5-10400 would be a massive upgrade for not much more money.

Pricing is all over the place depending on where you shop. In the US, you'll find it between USD 36 and USD 50, with Newegg typically offering the best deal on refurbished units. European buyers face a wider spread, from EUR 73 to EUR 113 across German, Spanish, French, and Italian listings. That's a big gap, so it pays to shop around. Canadian pricing runs CAD 53 to CAD 89. At the low end of those ranges, this chip makes sense for a bare-bones build. At the high end, you're getting close to used Ryzen 3 or older i3 territory, which would be a much better buy.

The Intel Celeron G5900 is a budget desktop processor that sits at the very bottom of Intel's Comet Lake lineup. It's a dual-core, dual-thread chip running at 3.4GHz with no turbo boost, built for basic computing tasks like web browsing, office work, and light media playback. At USD 36 to USD 50 on the used and refurbished market, it's one of the cheapest ways to get onto the LGA 1200 platform.

People searching for this chip usually want to know if it's good enough for a basic home PC or a cheap office build. The short answer is yes, but only if your expectations are realistic. This is not a gaming CPU, and it's not going to handle heavy multitasking. What it does well is run Windows 10 or 11 for simple tasks without costing much at all.

One thing to keep in mind: there's no cooler in the box. Intel says the thermal solution is not included, so you'll need to budget for a cheap LGA 1200 cooler unless you already have one lying around. That 58W TDP means even a basic cooler will do the job, but it's still an extra cost to factor in.

Skip the G5900 if you plan to do any real multitasking, video editing, or gaming. Content creators, streamers, and anyone running virtual machines should look at used Ryzen 5 or i5 chips instead. If you're building a system you'll rely on daily for work with multiple apps open, the 2-core limit will frustrate you within a week. Also skip it if you're paying the high end of the European price range, EUR 113 for a Celeron is a bad deal when used i3s and Ryzen 3s sit in the same bracket.

Should you buy the Intel Celeron G5900? If you're building a basic office PC, a home theater box, or a cheap NAS and you can find it for USD 36 to USD 40, sure. It's a functional chip that handles everyday tasks without drama. The single-thread performance is better than you'd expect, and the low power draw keeps things cool and quiet.

But if you plan to do anything beyond web browsing and document editing, look elsewhere. The 2-core, 2-thread design is a hard ceiling. A used Ryzen 3 or i3 from the same era will cost a bit more and deliver dramatically better performance. The G5900 is a stopgap chip, not a foundation for a system you'll want to keep using for years.
