Quick Answers

So, is Core i3-8100 better than Opteron 6344?

Not really, because they are built for different jobs. Opteron 6344 makes more sense for workstation-style multi-core throughput, while Core i3-8100 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, Core i3-8100 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 i3-8100 is the better buy right now. Core i3-8100 comes in $298 cheaper on MSRP at $117 MSRP versus $415 MSRP, and it still gives you 0.1% better PassMark. The compromise is that Opteron 6344 is still the better pure gaming CPU with a 13.2% average FPS lead across 50 shared CPU game tests in our data. It is also 254.9% better value on MSRP (51.9 vs 14.6 PassMark/$), 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 i3-8100 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2012) and more multi-core headroom with 4 cores / 4 threads instead of 12/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
