Quick Answers

So, is Pentium G645 better than Pentium M 740?

Yes. Pentium G645 is the better all-around CPU here. It gives you a 1.2% average FPS lead across 49 shared CPU game tests in our data, 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, Pentium G645 is the better pick. According to our tests, it delivers 1.2% more average FPS across 49 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Pentium G645 is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

Pentium G645 is the better buy right now. Pentium G645 comes in at an unclear MSRP at $80 MSRP versus unclear MSRP, and it still gives you a 1.2% average FPS lead across 49 shared CPU game tests in our data. It is also 100.0% better value on MSRP (18.1 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium G645 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2005) 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.
