Quick Answers

So, is Celeron N2940 better than Pentium 3558U?

Yes. Celeron N2940 is the better all-around CPU here. It gives you a 1.7% average FPS lead across 50 shared CPU game tests in our data, 1.2% 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 N2940 is the better pick. According to our tests, it delivers 1.7% 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 N2940 is the stronger fit. You are getting 1.2% better PassMark, backed by 4 cores and 4 threads.

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

Celeron N2940 still makes the most sense overall. Celeron N2940 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 1.7% average FPS lead across 50 shared CPU game tests in our data.

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

Celeron N2940 makes more sense long term for 2026 and beyond. You are getting 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.
