Quick Answers

So, is Celeron 6305 better than Celeron B810?

It depends on what you want from the system. For gaming, Celeron 6305 is ahead with a 0.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron B810 pulls ahead with 0.7% better PassMark. Celeron 6305 also has the bigger cache pool with 100% larger total L3 cache (4 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Celeron B810 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 6305 is still the much better call for a fresh build. Celeron 6305 comes in 24.4% more expensive on MSRP at $107 MSRP versus $86 MSRP, and it still gives you a 0.4% average FPS lead across 50 shared CPU game tests in our data. Celeron B810 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 25.3% better value on paper (24.3 vs 19.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA988.

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 2011) and 100% larger total L3 cache (4 MB vs 2 MB). That makes it the safer long-term bet.
