Quick Answers

So, is Celeron 3755U better than Celeron M 723?

Yes. Celeron 3755U is the better all-around CPU here. It gives you a 1.2% average FPS lead across 50 shared CPU game tests in our data, 525% better Geekbench multi-core, 0.2% higher 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 1.2% 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 3755U is the stronger fit. You are getting 525% better Geekbench multi-core, backed by 2 cores and 2 threads.

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

Celeron 3755U is the easy recommendation for a fresh desktop build. Celeron 3755U comes in at an unclear MSRP at unclear MSRP versus $161 MSRP, and it still gives you a 1.2% average FPS lead across 50 shared CPU game tests in our data. Celeron M 723 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games.

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 2008) and more multi-core headroom with 2 cores / 2 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
