Quick Answers

So, is Core i3-6320 better than Opteron 3380?

Not really, because they are built for different jobs. Opteron 3380 makes more sense for workstation-style multi-core throughput, while Core i3-6320 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i3-6320 is the better pick. According to our tests, it delivers 2.4% 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 i3-6320 is the stronger fit. You are getting 1.4% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-6320 is the better buy right now. Core i3-6320 comes in $69 cheaper on MSRP at $160 MSRP versus $229 MSRP, and it still gives you a 2.4% average FPS lead across 50 shared CPU game tests in our data. It is also 45.2% better value on MSRP (27.6 vs 19.0 PassMark/$), 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 i3-6320 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2012) and more multi-core headroom with 2 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.
