Quick Answers

So, is Core 2 Duo SL9400 better than Core 2 Duo P7350?

It depends on what you want from the system. For gaming, Core 2 Duo P7350 is ahead with a 0.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo SL9400 pulls ahead with 0.2% better PassMark. Core 2 Duo SL9400 also has the bigger cache pool with 100% larger total L3 cache (6 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Core 2 Duo SL9400 is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 100% larger total L3 cache (6 MB vs 3 MB).

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

Core 2 Duo SL9400 is the better buy right now. Core 2 Duo SL9400 comes in at an unclear MSRP at $284 MSRP versus unclear MSRP, and it still gives you 0.2% better PassMark. The compromise is that Core 2 Duo P7350 is still the better pure gaming CPU with a 0.6% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (7.5 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core 2 Duo SL9400 makes more sense long term for 2026 and beyond. You are getting 100% larger total L3 cache (6 MB vs 3 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.
