Core i7-4940MX vs Opteron 6380: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Core i7-4940MX

2014

Why buy it

  • Draws 57W instead of 115W, a 58W reduction.

Trade-offs

  • Less compelling for workstation-style loads than Opteron 6380, which brings 16 cores / 16 threads.

Opteron 6380

2012

Why buy it

  • Better for workstations and heavier parallel workloads: 16 cores / 16 threads.

Trade-offs

  • Lower PassMark (6,687 vs 6,783).
  • Launch MSRP is still $551 MSRP, while Core i7-4940MX mostly shows up through inconsistent older-market listings.
  • 101.8% higher power demand at 115W vs 57W.

Quick Answers

So, is Core i7-4940MX better than Opteron 6380?
Not really, because they are built for different jobs. Opteron 6380 makes more sense for workstation-style multi-core throughput, while Core i7-4940MX 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 i7-4940MX is the better pick. According to our tests, it delivers 1.3% 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 i7-4940MX is the stronger fit. You are getting 1.4% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-4940MX is still the faster CPU overall, but Opteron 6380 is easier to justify if budget matters more than peak performance. Core i7-4940MX comes in at an unclear MSRP at unclear MSRP versus $551 MSRP, and it still gives you a 1.3% average FPS lead across 50 shared CPU game tests in our data. Opteron 6380 is also 100.0% better value on MSRP (12.1 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.
Which one is more future-proof for 2026 and beyond?
Core i7-4940MX makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012) and more multi-core headroom with 4 cores / 8 threads instead of 16/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
