Quick Answers

So, is Core i7-9700K 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 i7-9700K 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 i7-9700K is the better pick. According to our tests, it delivers 140.7% 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 i7-9700K is the stronger fit. You are getting 230.4% better PassMark, backed by 8 cores and 8 threads. It also has the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

Core i7-9700K is the better buy right now. Core i7-9700K comes in 68.1% more expensive on MSRP at $385 MSRP versus $229 MSRP, and it still gives you a 140.7% average FPS lead across 50 shared CPU game tests in our data. It is also 96.5% better value on MSRP (37.4 vs 19.0 PassMark/$), 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 i7-9700K makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2012), 50% larger total L3 cache (12 MB vs 8 MB), and more multi-core headroom with 8 cores / 8 threads instead of 8/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
