Quick Answers

So, is Celeron G5905T better than Core 2 Duo T6670?

Yes. Celeron G5905T is the better all-around CPU here. It gives you a 3.7% average FPS lead across 35 shared CPU game tests in our data, 197.6% better Geekbench multi-core, 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, Celeron G5905T is the better pick. According to our tests, it delivers 3.7% more average FPS across 35 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Celeron G5905T is the stronger fit. You are getting 197.6% better Geekbench multi-core, backed by 2 cores and 2 threads. It also has the larger cache pool with 100% larger total L3 cache (4 MB vs 2 MB).

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

Celeron G5905T is the better buy right now. Celeron G5905T comes in at an unclear MSRP at $50 MSRP versus unclear MSRP, and it still gives you a 3.7% average FPS lead across 35 shared CPU game tests in our data. It is also 100.0% better value on MSRP (47.1 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Celeron G5905T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2009), 100% larger total L3 cache (4 MB vs 2 MB), and more multi-core headroom with 2 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.
