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

Celeron B840

2011

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Sandy Bridge), while E-450 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $86 MSRP, while E-450 mostly shows up through inconsistent older-market listings.

E-450

2011

Why buy it

Trade-offs

❌Lower PassMark (1,063 vs 1,065).
❌No integrated graphics, while Celeron B840 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron B840 better than E-450?

Yes. Celeron B840 is the better all-around CPU here. It gives you a 1.7% average FPS lead across 50 shared CPU game tests in our data, 0.2% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Celeron B840 is the better pick. According to our tests, it delivers 1.7% 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 B840 is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 2 threads.

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

Celeron B840 is the better buy right now. Celeron B840 comes in at an unclear MSRP at $86 MSRP versus unclear MSRP, and it still gives you a 1.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (12.4 vs 0.0 PassMark/$), 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 B840 makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
