Quick Answers

So, is Core i5-3330 better than FX-8100?
It depends on what you want from the system. For gaming, FX-8100 is ahead with a 13.5% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-3330 pulls ahead with 0.1% better PassMark. FX-8100 also has the bigger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-3330 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-3330 is the better buy right now. Core i5-3330 comes in $118 cheaper on MSRP at $182 MSRP versus $300 MSRP, and it still gives you 0.1% better PassMark. The compromise is that FX-8100 is still the better pure gaming CPU with a 13.5% average FPS lead across 50 shared CPU game tests in our data. It is also 65.0% better value on MSRP (22.5 vs 13.7 PassMark/$), 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 i5-3330 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2011) and more multi-core headroom with 4 cores / 4 threads instead of 8/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
