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

Celeron 3755U

2015

Why buy it

✅Draws 15W instead of 65W, a 50W reduction.
✅100+% more PCIe lanes (12 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics (Broadwell), while Pentium E6500 needs a discrete GPU.

Trade-offs

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

Pentium E6500

2009

Why buy it

Trade-offs

❌Lower PassMark (1,175 vs 1,182).
❌Launch MSRP is still $84 MSRP, while Celeron 3755U mostly shows up through inconsistent older-market listings.
❌333.3% higher power demand at 65W vs 15W.
❌No integrated graphics, while Celeron 3755U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron 3755U better than Pentium E6500?

Yes. Celeron 3755U is the better all-around CPU here. It gives you a 1.4% average FPS lead across 49 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 3755U is the better pick. According to our tests, it delivers 1.4% more average FPS across 49 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Celeron 3755U is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

Celeron 3755U is still the much better call for a fresh build. Celeron 3755U comes in at an unclear MSRP at unclear MSRP versus $84 MSRP, and it still gives you a 1.4% average FPS lead across 49 shared CPU game tests in our data. Pentium E6500 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (14.0 vs 0.0 PassMark/$), 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 3755U 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.
