Celeron J3355

2016

Why buy it

✅Draws 10W instead of 65W, a 55W reduction.
✅100+% more PCIe lanes (6 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 500, while Pentium E6600 needs a discrete GPU.

Trade-offs

❌Fewer obvious downsides in this matchup outside of normal market pricing swings.

Pentium E6600

2010

Why buy it

Trade-offs

❌Lower PassMark (1,194 vs 1,203).
❌Launch MSRP is still $84 MSRP, while Celeron J3355 mostly shows up through inconsistent older-market listings.
❌550% higher power demand at 65W vs 10W.
❌No integrated graphics, while Celeron J3355 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron J3355 better than Pentium E6600?

Yes. Celeron J3355 is the better all-around CPU here. It gives you 0.8% 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 3471.4% 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 0.8% 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 $84 MSRP, and it still gives you 0.8% higher PassMark. Pentium E6600 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (14.2 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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.
