Quick Answers

So, is Celeron J3455E better than Core m3-6Y30?

Yes. Celeron J3455E is the better all-around CPU here. It gives you a 2.6% average FPS lead across 50 shared CPU game tests in our data, 0.6% 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 J3455E is the better pick. According to our tests, it delivers 2.6% 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 J3455E is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 4 threads.

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

Celeron J3455E is the easy recommendation for a fresh desktop build. Celeron J3455E comes in at an unclear MSRP at unclear MSRP versus $281 MSRP, and it still gives you a 2.6% average FPS lead across 50 shared CPU game tests in our data. Core m3-6Y30 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 2.6% in the shared gaming data.

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

Celeron J3455E makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2015) and more multi-core headroom with 4 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
