Quick Answers

So, is Celeron G3900TE better than Core i3-2105?

It depends on what you want from the system. For gaming, Core i3-2105 is ahead with a 0.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron G3900TE pulls ahead with 0.7% better PassMark. Core i3-2105 also has the bigger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Celeron G3900TE is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 2 threads.

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

Celeron G3900TE is the better buy right now. Celeron G3900TE comes in $96 cheaper on MSRP at $42 MSRP versus $138 MSRP, and it still gives you 0.7% better PassMark. The compromise is that Core i3-2105 is still the better pure gaming CPU with a 0.1% average FPS lead across 50 shared CPU game tests in our data. It is also 230.9% better value on MSRP (44.0 vs 13.3 PassMark/$), 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 G3900TE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2011) and more multi-core headroom with 2 cores / 2 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
