Celeron 3205U

2015

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics (Broadwell), while Core 2 Duo E8135 needs a discrete GPU.

Trade-offs

❌1063.6% higher power demand at 512W vs 44W.

Core 2 Duo E8135

2009

Why buy it

✅Draws 44W instead of 512W, a 468W reduction.

Trade-offs

❌Lower PassMark (1,020 vs 1,025).
❌Launch MSRP is still $200 MSRP, while Celeron 3205U mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while Celeron 3205U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron 3205U better than Core 2 Duo E8135?

Yes. Celeron 3205U is the better all-around CPU here. It gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data, 0.5% 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 3205U is the better pick. According to our tests, it delivers 1.6% 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 3205U 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 3205U is still the much better call for a fresh build. Celeron 3205U comes in at an unclear MSRP at unclear MSRP versus $200 MSRP, and it still gives you a 1.6% average FPS lead across 50 shared CPU game tests in our data. Core 2 Duo E8135 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (5.1 vs 0.0 PassMark/$), 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 3205U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2009) 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.
