Quick Answers

So, is Core 2 Duo P8700 better than Celeron J4105?

It depends on what you want from the system. For gaming, Core 2 Duo P8700 is ahead with a 1.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron J4105 pulls ahead with 0.5% better PassMark. Celeron J4105 also has the bigger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Celeron J4105 is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 4 threads. It also has the larger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

Core 2 Duo P8700 is the better buy right now. Core 2 Duo P8700 comes in at an unclear MSRP at $241 MSRP versus unclear MSRP, and it still gives you a 1.4% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Celeron J4105 is still stronger for heavier multi-core work with 0.5% better PassMark. It is also 100.0% better value on MSRP (11.6 vs 0.0 PassMark/$), 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 J4105 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2009), 33.3% larger total L3 cache (4 MB vs 3 MB), and more multi-core headroom with 4 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.
