Quick Answers

So, is Celeron 6305 better than Pentium G3258?
It depends on what you want from the system. For gaming, Pentium G3258 is ahead with 77.8% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Celeron 6305 pulls ahead with 0.7% better PassMark. Celeron 6305 also has the bigger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).
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 0.7% better PassMark, 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 42.7% more expensive on MSRP at $107 MSRP versus $75 MSRP, and it still gives you 0.7% better PassMark. Pentium G3258 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 41.7% better value on paper (27.5 vs 19.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1150.
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 2014), 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.
