Quick Answers

So, is Celeron G465 better than Core 2 Duo E6400?

It depends on what you want from the system. For gaming, Core 2 Duo E6400 is ahead with a 1.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron G465 pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron G465 is the stronger fit. You are getting 0.9% better PassMark, backed by 1 cores and 2 threads.

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

Celeron G465 is the better buy right now. Celeron G465 comes in $113 cheaper on MSRP at $70 MSRP versus $183 MSRP, and it still gives you 0.9% better PassMark. The compromise is that Core 2 Duo E6400 is still the better pure gaming CPU with a 1.1% average FPS lead across 50 shared CPU game tests in our data. It is also 163.7% better value on MSRP (16.9 vs 6.4 PassMark/$), 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 G465 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2006) and more multi-core headroom with 1 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
