Quick Answers

So, is Pentium 6805 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 Pentium 6805 is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Pentium 6805 is the stronger fit. You are getting 1.5% better PassMark, backed by 2 cores and 4 threads.

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

Pentium 6805 is the better buy right now. Pentium 6805 comes in $68 cheaper on MSRP at $161 MSRP versus $229 MSRP, and it still gives you 1.5% better PassMark. The compromise is that Opteron 3380 is still the better pure gaming CPU with a 20.2% average FPS lead across 50 shared CPU game tests in our data. It is also 44.4% better value on MSRP (27.5 vs 19.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Pentium 6805 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 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.
