Celeron N2920

2013

Why buy it

✅Draws 7W instead of 44W, a 37W reduction.
✅100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Bay Trail), while Core 2 Duo E8135 needs a discrete GPU.

Trade-offs

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

Core 2 Duo E8135

2009

Why buy it

Trade-offs

❌Lower PassMark (1,020 vs 1,030).
❌Launch MSRP is still $200 MSRP, while Celeron N2920 mostly shows up through inconsistent older-market listings.
❌528.6% higher power demand at 44W vs 7W.
❌No integrated graphics, while Celeron N2920 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron N2920 better than Core 2 Duo E8135?

Yes. Celeron N2920 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 N2920 has the edge because it leads the single-thread side of this matchup with 198.5% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Celeron N2920 is the stronger fit. You are getting 1% better PassMark, backed by 4 cores and 4 threads.

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

Celeron N2920 is still the much better call for a fresh build. Celeron N2920 comes in at an unclear MSRP at unclear MSRP versus $200 MSRP, and it still gives you 1.0% higher PassMark. Core 2 Duo E8135 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (5.1 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on P.

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

Celeron N2920 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2009) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
