Celeron B820

2012

Why buy it

✅Better for gaming: +3.9% 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 Core 2 Duo T5200 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $86 MSRP, while Core 2 Duo T5200 mostly shows up through inconsistent older-market listings.
❌1650% higher power demand at 35W vs 2W.

Core 2 Duo T5200

2006

Why buy it

✅Draws 2W instead of 35W, a 33W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Celeron B820 across 50 shared CPU benchmark tests.
❌Lower PassMark (705 vs 765).
❌No integrated graphics, while Celeron B820 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron B820 better than Core 2 Duo T5200?

Yes. Celeron B820 is the better all-around CPU here. It gives you a 3.9% average FPS lead across 50 shared CPU game tests in our data, 8.5% 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 B820 is the better pick. According to our tests, it delivers 3.9% 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 B820 is the stronger fit. You are getting 8.5% better PassMark, backed by 2 cores and 2 threads.

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

Celeron B820 is the better buy right now. Celeron B820 comes in at an unclear MSRP at $86 MSRP versus unclear MSRP, and it still gives you a 3.9% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (8.9 vs 0.0 PassMark/$), 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 B820 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2006) and 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.
