Core i5-10400F

2020

Why buy it

  • Costs $180 less on MSRP ($160 MSRP vs $340 MSRP).
  • Delivers 28.0% more PassMark for each dollar spent, at 81.4 vs 63.6 PassMark/$ ($160 MSRP vs $340 MSRP).
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Includes a boxed cooler (Yes), unlike Core 5 120.

Trade-offs

  • Worse for gaming: lower average FPS than Core 5 120 across 50 shared CPU benchmark tests.
  • Lower PassMark (13,029 vs 21,629).
  • Smaller total L3 cache (12 MB vs 18 MB).
  • Older platform position on LGA1200 with DDR4, while Core 5 120 moves to LGA1700 and DDR5.

Quick Answers

So, is Core 5 120 better than Core i5-10400F?
Yes. Core 5 120 is the better all-around CPU here. It gives you a 8.9% average FPS lead across 50 shared CPU game tests in our data, 66% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core 5 120 is the better pick. According to our tests, it delivers 8.9% 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 5 120 is the stronger fit. You are getting 66% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (18 MB vs 12 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core 5 120 is still the faster CPU overall, but Core i5-10400F is easier to justify if budget matters more than peak performance. Core 5 120 comes in 112.5% more expensive on MSRP at $340 MSRP versus $160 MSRP, and it still gives you a 8.9% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F is also 28.0% better value on MSRP (81.4 vs 63.6 PassMark/$), which is why it can still make sense for tighter-budget builds on paper. That said, if you already own a compatible LGA1200 + DDR4 setup, Core i5-10400F 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?
Core 5 120 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2020), a healthier platform with LGA1700 and DDR5 instead of LGA1200, 50% larger total L3 cache (18 MB vs 12 MB), and more multi-core headroom with 6 cores / 12 threads instead of 6/12. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
