Quick Answers

So, is Celeron 1005M better than Core 2 Duo E8435?

Yes. Celeron 1005M is the better all-around CPU here. It gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data, 1.1% 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 1005M is the better pick. According to our tests, it delivers 1.8% 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 1005M is the stronger fit. You are getting 1.1% better PassMark, backed by 2 cores and 2 threads.

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

Celeron 1005M is the better buy right now. Celeron 1005M comes in $64 cheaper on MSRP at $86 MSRP versus $150 MSRP, and it still gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data. It is also 76.3% better value on MSRP (13.0 vs 7.4 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Celeron 1005M 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 2 cores / 2 threads instead of 2/2.
