Quick Answers

So, is Celeron 420 better than Celeron 2.70?

Yes. Celeron 420 is the better all-around CPU here. It gives you a 9.6% average FPS lead across 50 shared CPU game tests in our data, 4.2% better PassMark, 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 420 is the better pick. According to our tests, it delivers 9.6% 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 420 is the stronger fit. You are getting 4.2% better PassMark, backed by 1 cores and 1 threads.

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

Celeron 420 is the better buy right now. Celeron 420 comes in $10 cheaper on MSRP at $39 MSRP versus $49 MSRP, and it still gives you a 9.6% average FPS lead across 50 shared CPU game tests in our data. It is also 30.9% better value on MSRP (10.9 vs 8.3 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Celeron 420 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2007 vs 2003) and more multi-core headroom with 1 cores / 1 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
