Quick Answers

So, is Core i5-661 better than Celeron G3920?

Yes. Core i5-661 is the better all-around CPU here. It gives you a 1.1% average FPS lead across 50 shared CPU game tests in our data and 1.2% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i5-661 is the better pick. According to our tests, it delivers 1.1% 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, Core i5-661 is the stronger fit. You are getting 1.2% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-661 is still the much better call for a fresh build. Core i5-661 comes in 390.0% more expensive on MSRP at $196 MSRP versus $40 MSRP, and it still gives you a 1.1% average FPS lead across 50 shared CPU game tests in our data. Celeron G3920 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 384.0% better value on paper (59.0 vs 12.2 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

Which one is more future-proof for 2026 and beyond?

Celeron G3920 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2010). That makes it the safer long-term bet.
