Quick Answers

So, is Celeron N4000C better than Phenom X4 9150e?

Yes. Celeron N4000C is the better all-around CPU here. It gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data, 0.2% 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 N4000C is the better pick. According to our tests, it delivers 0.1% 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 N4000C is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 100% larger total L3 cache (4 MB vs 2 MB).

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

Celeron N4000C still makes the most sense overall. Celeron N4000C comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data.

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

Celeron N4000C makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2008), 100% larger total L3 cache (4 MB vs 2 MB), and more multi-core headroom with 2 cores / 2 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
