Celeron G4900 vs Xeon E5-2403: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Celeron G4900

2018

Why buy it

✅Draws 54W instead of 80W, a 26W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 610, while Xeon E5-2403 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (6 MB vs 10 MB).
❌Less compelling for workstation-style loads than Xeon E5-2403, which brings 4 cores / 4 threads.
❌Launch MSRP is still $42 MSRP, while Xeon E5-2403 mostly shows up through inconsistent older-market listings.

Xeon E5-2403

2012

Why buy it

✅+66.7% larger total L3 cache (10 MB vs 6 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 4 threads.

Trade-offs

❌Lower PassMark (2,367 vs 2,370).
❌48.1% higher power demand at 80W vs 54W.
❌No integrated graphics, while Celeron G4900 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron G4900 better than Xeon E5-2403?

Not really, because they are built for different jobs. Xeon E5-2403 makes more sense for workstation-style multi-core throughput, while Celeron G4900 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Celeron G4900 is the better pick. According to our tests, it delivers 1.3% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Celeron G4900 is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Celeron G4900 is the better buy right now. Celeron G4900 comes in at an unclear MSRP at $42 MSRP versus unclear MSRP, and it still gives you a 1.3% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (56.4 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

Which one is more future-proof for 2026 and beyond?

Celeron G4900 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2012) and more multi-core headroom with 2 cores / 2 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
