Quick Answers

So, is Core 2 Duo P9700 better than Celeron Dual-Core T3100?

Yes. Core 2 Duo P9700 is the better all-around CPU here. It gives you a 1.9% average FPS lead across 50 shared CPU game tests in our data, 0.3% 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, Core 2 Duo P9700 is the better pick. According to our tests, it delivers 1.9% 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, Core 2 Duo P9700 is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 2 threads.

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

Core 2 Duo P9700 still makes the most sense overall. Core 2 Duo P9700 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 1.9% average FPS lead across 50 shared CPU game tests in our data.

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

Core 2 Duo P9700 makes more sense long term for 2026 and beyond. You are getting 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.
