Quick Answers

So, is Pentium G3240 better than Celeron M 575?

Yes. Pentium G3240 is the better all-around CPU here. It gives you a 1.0% average FPS lead across 50 shared CPU game tests in our data, 0.7% 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 G3240 is the better pick. According to our tests, it delivers 1.0% 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, Pentium G3240 is the stronger fit. You are getting 0.7% better PassMark, backed by 2 cores and 2 threads.

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

Pentium G3240 is still the much better call for a fresh build. Pentium G3240 comes in 3.5% more expensive on MSRP at $89 MSRP versus $86 MSRP, and it still gives you a 1.0% average FPS lead across 50 shared CPU game tests in our data. Celeron M 575 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 2.8% better value on paper (22.3 vs 21.7 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.

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

Pentium G3240 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 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.
