Quick Answers

So, is Celeron N4505 better than Athlon II X4 620?

It depends on what you want from the system. For gaming, Athlon II X4 620 is ahead with a 4.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron N4505 pulls ahead with 0.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron N4505 is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 2 threads.

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

Celeron N4505 is still the much better call for a fresh build. Celeron N4505 comes in at an unclear MSRP at unclear MSRP versus $99 MSRP, and it still gives you 0.5% better PassMark. Athlon II X4 620 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (20.5 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3.

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

Celeron N4505 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2009) and more multi-core headroom with 2 cores / 2 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
