Core i7-980X vs Core i7-4940MX: Pros, Cons & Final Verdict

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

Core i7-980X

2010

Why buy it

  • +0.5% higher PassMark.
  • +50% larger total L3 cache (12 MB vs 8 MB).

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-4940MX across 50 shared CPU benchmark tests.
  • Launch MSRP is still $999 MSRP, while Core i7-4940MX mostly shows up through inconsistent older-market listings.
  • 128.1% higher power demand at 130W vs 57W.

Core i7-4940MX

2014

Why buy it

  • Better for gaming: +3.3% higher average FPS across 50 shared CPU benchmark tests.
  • Draws 57W instead of 130W, a 73W reduction.

Trade-offs

  • Lower PassMark (6,783 vs 6,817).
  • Smaller total L3 cache (8 MB vs 12 MB).

Quick Answers

So, is Core i7-4940MX better than Core i7-980X?
It depends on what you want from the system. For gaming, Core i7-4940MX is ahead with a 3.3% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-980X pulls ahead with 0.5% better PassMark. Core i7-980X also has the bigger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i7-980X is the stronger fit. You are getting 0.5% better PassMark, backed by 6 cores and 12 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 i7-4940MX is still the much better call for a fresh build. Core i7-4940MX comes in at an unclear MSRP at unclear MSRP versus $999 MSRP, and it still gives you a 3.3% average FPS lead across 50 shared CPU game tests in our data. Core i7-980X only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (6.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1366.
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 2010). That makes it the safer long-term bet.
