Celeron G3900E

2016

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 510, while Pentium Dual Core T3400 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $107 MSRP, while Pentium Dual Core T3400 mostly shows up through inconsistent older-market listings.
❌3400% higher power demand at 35W vs 1W.

Pentium Dual Core T3400

2008

Why buy it

✅Draws 1W instead of 35W, a 34W reduction.

Trade-offs

❌Lower PassMark (2,026 vs 2,034).
❌No integrated graphics, while Celeron G3900E can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron G3900E better than Pentium Dual Core T3400?

Yes. Celeron G3900E is the better all-around CPU here. It gives you a 1.5% average FPS lead across 50 shared CPU game tests in our data, 0.4% 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 G3900E is the better pick. According to our tests, it delivers 1.5% 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 G3900E is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 2 threads.

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

Celeron G3900E is the better buy right now. Celeron G3900E comes in at an unclear MSRP at $107 MSRP versus unclear MSRP, and it still gives you a 1.5% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (19.0 vs 0.0 PassMark/$), 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 G3900E makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2008) 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.
