Quick Answers

So, is Celeron 6305 better than Pentium G2140?

Yes. Celeron 6305 is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data, 34.3% better Geekbench multi-core, 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 6305 is the better pick. According to our tests, it delivers 0.2% 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 6305 is the stronger fit. You are getting 34.3% better Geekbench multi-core, backed by 2 cores and 2 threads. It also has the larger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

Celeron 6305 is still the much better call for a fresh build. Celeron 6305 comes in 7.0% more expensive on MSRP at $107 MSRP versus $100 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. Pentium G2140 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2013 platform. Even with 7.8% better value on paper (20.9 vs 19.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.

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

Celeron 6305 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2013), 33.3% larger total L3 cache (4 MB vs 3 MB), 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.
