Quick Answers

So, is Opteron 6366 HE better than Core i7-3720QM?

Not really, because they are built for different jobs. Opteron 6366 HE makes more sense for workstation-style multi-core throughput, while Core i7-3720QM 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, Opteron 6366 HE is the stronger fit. You are getting 0.4% better PassMark, backed by 16 cores and 16 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Opteron 6366 HE still makes the most sense overall. Opteron 6366 HE comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.4% better PassMark.

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

Opteron 6366 HE makes more sense long term for 2026 and beyond. You are getting 33.3% larger total L3 cache (8 MB vs 6 MB) and more multi-core headroom with 16 cores / 16 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
