Quick Answers

So, is Core 2 Duo P8400 better than Pentium Gold 4415Y?

It depends on what you want from the system. For gaming, Core 2 Duo P8400 is ahead with a 1.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium Gold 4415Y pulls ahead with 1% better PassMark. Core 2 Duo P8400 also has the bigger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Pentium Gold 4415Y is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 4 threads.

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

Core 2 Duo P8400 is the better buy right now. Core 2 Duo P8400 comes in at an unclear MSRP at $209 MSRP versus unclear MSRP, and it still gives you a 1.8% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Pentium Gold 4415Y is still stronger for heavier multi-core work with 1% better PassMark. It is also 100.0% better value on MSRP (11.9 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium Gold 4415Y makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2008) and more multi-core headroom with 2 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
