Quick Answers

So, is Celeron G3900TE better than Phenom II X3 B77?

It depends on what you want from the system. For gaming, Phenom II X3 B77 is ahead with a 0.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron G3900TE pulls ahead with 0.3% better PassMark. Phenom II X3 B77 also has the bigger cache pool with 200% larger total L3 cache (6 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 0.3% 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 $239 cheaper on MSRP at $42 MSRP versus $281 MSRP, and it still gives you 0.3% better PassMark. The compromise is that Phenom II X3 B77 is still the better pure gaming CPU with a 0.9% average FPS lead across 50 shared CPU game tests in our data. It is also 571.2% better value on MSRP (44.0 vs 6.6 PassMark/$), 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 2010) and more multi-core headroom with 2 cores / 2 threads instead of 3/3.
