Quick Answers

So, is Celeron 857 better than Celeron B720?

Yes. Celeron 857 is the better all-around CPU here. It gives you a 5.9% average FPS lead across 50 shared CPU game tests in our data and 6% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Celeron 857 is the better pick. According to our tests, it delivers 5.9% 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 857 is the stronger fit. You are getting 6% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 33.3% larger total L3 cache (2 MB vs 1.5 MB).

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

Celeron 857 is still the much better call for a fresh build. Celeron 857 comes in 91.4% more expensive on MSRP at $134 MSRP versus $70 MSRP, and it still gives you a 5.9% average FPS lead across 50 shared CPU game tests in our data. Celeron B720 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 80.6% better value on paper (9.5 vs 5.3 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on G2.

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

Celeron B720 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2011). That makes it the safer long-term bet.
