Celeron B720 vs Opteron 154: Pros, Cons & Final Verdict

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

Celeron B720

2012

Why buy it

✅Better for gaming: +4.7% higher average FPS across 50 shared CPU benchmark tests.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics (Sandy Bridge), while Opteron 154 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $70 MSRP, while Opteron 154 mostly shows up through inconsistent older-market listings.

Opteron 154

2005

Why buy it

Trade-offs

❌Worse for gaming: lower average FPS than Celeron B720 across 50 shared CPU benchmark tests.
❌Lower PassMark (655 vs 665).
❌No integrated graphics, while Celeron B720 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron B720 better than Opteron 154?

Not really, because they are built for different jobs. Opteron 154 makes more sense for workstation-style multi-core throughput, while Celeron B720 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 B720 is the better pick. According to our tests, it delivers 4.7% 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 B720 is the stronger fit. You are getting 1.5% better PassMark, backed by 1 cores and 1 threads.

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

Celeron B720 is the better buy right now. Celeron B720 comes in at an unclear MSRP at $70 MSRP versus unclear MSRP, and it still gives you a 4.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (9.5 vs 0.0 PassMark/$), 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 B720 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2005) and more multi-core headroom with 1 cores / 1 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
