Athlon II Neo K345 vs Celeron J3355: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Athlon II Neo K345

2010

Why buy it

✅Draws 1W instead of 10W, a 9W reduction.

Trade-offs

❌Lower PassMark (1,191 vs 1,203).
❌Launch MSRP is still $50 MSRP, while Celeron J3355 mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while Celeron J3355 can still boot and troubleshoot without a discrete GPU.

Celeron J3355

2016

Why buy it

✅100+% more PCIe lanes (6 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 500, while Athlon II Neo K345 needs a discrete GPU.

Trade-offs

❌900% higher power demand at 10W vs 1W.

Quick Answers

So, is Celeron J3355 better than Athlon II Neo K345?

Yes. Celeron J3355 is the better all-around CPU here. It gives you 1% 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 J3355 has the edge because it leads the single-thread side of this matchup with 78.6% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Celeron J3355 is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

Celeron J3355 is still the much better call for a fresh build. Celeron J3355 comes in at an unclear MSRP at unclear MSRP versus $50 MSRP, and it still gives you 1.0% higher PassMark. Athlon II Neo K345 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (23.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on S1.

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

Celeron J3355 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2010) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
