Core i9-9920X vs M3 Pro 11-Core: Pros, Cons & Final Verdict

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

Core i9-9920X

2018

Why buy it

  • Better for gaming: +3.7% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

  • Launch MSRP is still $1,189 MSRP, while M3 Pro 11-Core mostly shows up through inconsistent older-market listings.
  • Older platform position on LGA2066 with DDR4, while M3 Pro 11-Core moves to none and DDR5.

M3 Pro 11-Core

2023

Why buy it

  • Newer platform on none with DDR5 support instead of LGA2066 and DDR4.

Trade-offs

  • Worse for gaming: lower average FPS than Core i9-9920X across 50 shared CPU benchmark tests.
  • Lower PassMark (24,861 vs 24,974).

Quick Answers

So, is Core i9-9920X better than M3 Pro 11-Core?
Yes. Core i9-9920X is the better all-around CPU here. It gives you a 3.7% average FPS lead across 50 shared CPU game tests in our data and 0.5% better PassMark, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core i9-9920X is the better pick. According to our tests, it delivers 3.7% 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 i9-9920X is the stronger fit. You are getting 0.5% better PassMark, backed by 12 cores and 24 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i9-9920X is the better buy right now. Core i9-9920X comes in at an unclear MSRP at $1,189 MSRP versus unclear MSRP, and it still gives you a 3.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (21.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper. That said, if you already own a compatible none + DDR5 setup, M3 Pro 11-Core can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.
Which one is more future-proof for 2026 and beyond?
M3 Pro 11-Core makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2018) and a healthier platform with none and DDR5 instead of LGA2066. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
