Celeron G5905

2020

Why buy it

  • +89% higher Geekbench multi-core.
  • Integrated graphics onboard with UHD Graphics 610, while Core i5-12400F needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Core i5-12400F across 50 shared CPU benchmark tests.
  • Smaller total L3 cache (4 MB vs 18 MB).
  • Older platform position on LGA1200 with DDR4, while Core i5-12400F moves to LGA1700 and DDR5.
  • No boxed cooler included, unlike Core i5-12400F.

Core i5-12400F

2022

Why buy it

  • Better for gaming: +237.0% higher average FPS across 50 shared CPU benchmark tests.
  • +350% larger total L3 cache (18 MB vs 4 MB).
  • Newer platform on LGA1700 with DDR5 support instead of LGA1200 and DDR4.
  • 25% more PCIe lanes (20 vs 16) for storage and expansion-heavy builds.
  • Includes a boxed cooler (Yes), unlike Celeron G5905.

Trade-offs

  • Lower Geekbench multi-core (657 vs 1,242).
  • Launch MSRP is still $174 MSRP, while Celeron G5905 mostly shows up through inconsistent older-market listings.

Quick Answers

So, is Core i5-12400F better than Celeron G5905?
It depends on what you want from the system. For gaming, Core i5-12400F is ahead with a 237.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron G5905 pulls ahead with 89% better Geekbench multi-core. Core i5-12400F also has the bigger cache pool with 350% larger total L3 cache (18 MB vs 4 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Celeron G5905 is the stronger fit. You are getting 89% better Geekbench multi-core, backed by 2 cores and 2 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-12400F is the better buy right now. Core i5-12400F comes in at an unclear MSRP at $174 MSRP versus unclear MSRP, and it still gives you a 237.0% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Celeron G5905 is still stronger for heavier multi-core work with 89% better Geekbench multi-core. It is also 100.0% better value on MSRP (112.3 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper. That said, if you already own a compatible LGA1200 + DDR4 setup, Celeron G5905 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 i5-12400F makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2020), a healthier platform with LGA1700 and DDR5 instead of LGA1200, and 350% larger total L3 cache (18 MB vs 4 MB). That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
