Quick Answers

So, is Celeron G555 better than Pentium M 740?

It depends on what you want from the system. For gaming, Celeron G555 is ahead with a 1.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium M 740 pulls ahead with 0.6% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium M 740 is the stronger fit. You are getting 0.6% better PassMark, backed by 1 cores and 1 threads.

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

Celeron G555 is the better buy right now. Celeron G555 comes in at an unclear MSRP at $52 MSRP versus unclear MSRP, and it still gives you a 1.2% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Pentium M 740 is still stronger for heavier multi-core work with 0.6% better PassMark. It is also 100.0% better value on MSRP (27.4 vs 0.0 PassMark/$), 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 G555 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2005). That makes it the safer long-term bet.
