Core i5-12400F vs Core i5-14400T: Pros, Cons & Final Verdict

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

Core i5-12400F

2022

Why buy it

  • Better for gaming: +6.4% higher average FPS across 50 shared CPU benchmark tests.
  • 100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
  • Includes a boxed cooler (Yes), unlike Core i5-14400T.

Trade-offs

  • Lower PassMark (19,532 vs 20,911).
  • Launch MSRP is still $174 MSRP, while Core i5-14400T mostly shows up through inconsistent older-market listings.
  • 85.7% higher power demand at 65W vs 35W.

Core i5-14400T

2024

Why buy it

  • +7.1% higher PassMark.
  • Draws 35W instead of 65W, a 30W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Core i5-12400F across 50 shared CPU benchmark tests.
  • No boxed cooler included, unlike Core i5-12400F.

Quick Answers

So, is Core i5-14400T better than Core i5-12400F?
It depends on what you want from the system. For gaming, Core i5-12400F is ahead with a 6.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-14400T pulls ahead with 7.1% better PassMark.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-14400T is the stronger fit. You are getting 7.1% better PassMark, backed by 10 cores and 16 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-14400T is still the faster CPU overall, but Core i5-12400F is easier to justify if budget matters more than peak performance. Core i5-14400T comes in at an unclear MSRP at unclear MSRP versus $174 MSRP, and it still gives you 7.1% better PassMark. The compromise is that Core i5-12400F is still the better pure gaming CPU with a 6.4% average FPS lead across 50 shared CPU game tests in our data. Core i5-12400F is also 100.0% better value on MSRP (112.3 vs 0.0 PassMark/$), 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 i5-14400T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2022) and more multi-core headroom with 10 cores / 16 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
