Quick Answers

So, is Celeron G3930T better than Core i7-840QM?

It depends on what you want from the system. For gaming, Core i7-840QM is ahead with a 3.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron G3930T pulls ahead with 28.6% better Geekbench multi-core. Core i7-840QM also has the bigger cache pool with 300% larger total L3 cache (8 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Celeron G3930T is the stronger fit. You are getting 28.6% better Geekbench multi-core, backed by 2 cores and 2 threads.

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

Celeron G3930T is the better buy right now. Celeron G3930T comes in at an unclear MSRP at $42 MSRP versus unclear MSRP, and it still gives you 28.6% better Geekbench multi-core. The compromise is that Core i7-840QM is still the better pure gaming CPU with a 3.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (48.2 vs 0.0 PassMark/$), 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 G3930T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2010) and more multi-core headroom with 2 cores / 2 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
