Quick Answers

So, is Celeron G1840 better than Phenom II X3 B75?

It depends on what you want from the system. For gaming, Phenom II X3 B75 is ahead with a 2.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron G1840 pulls ahead with 0.1% better PassMark. Phenom II X3 B75 also has the bigger cache pool with 100% larger total L3 cache (6 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Celeron G1840 is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads.

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

Celeron G1840 is the better buy right now. Celeron G1840 comes in at an unclear MSRP at $35 MSRP versus unclear MSRP, and it still gives you 0.1% better PassMark. The compromise is that Phenom II X3 B75 is still the better pure gaming CPU with a 2.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (51.0 vs 0.0 PassMark/$), 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 G1840 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2009) and more multi-core headroom with 2 cores / 2 threads instead of 3/3. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
