About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, productivity performance, platform differences, power efficiency, pricing context, and upgrade path so you can see which CPU actually makes more sense.

Core i5-12400F

2022

Why buy it

  • Better for gaming: +8.6% higher average FPS across 4 shared CPU benchmark tests.
  • Draws 65W instead of 155W, a 90W reduction.
  • Newer platform on LGA1700 with DDR5 support instead of TR4 and DDR4.
  • 100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
  • Includes a boxed cooler (Yes), unlike EPYC 7351.

Trade-offs

  • Lower PassMark (19,532 vs 23,226).
  • Smaller total L3 cache (18 MB vs 64 MB).
  • Less compelling for workstation-style loads than EPYC 7351, which brings 16 cores / 32 threads.
  • Launch MSRP is still $174 MSRP, while EPYC 7351 mostly shows up through inconsistent older-market listings.

EPYC 7351

2017

Why buy it

  • +18.9% higher PassMark.
  • +255.6% larger total L3 cache (64 MB vs 18 MB).
  • Better for workstations and heavier parallel workloads: 16 cores / 32 threads.

Trade-offs

  • Worse for gaming: lower average FPS than Core i5-12400F across 4 shared CPU benchmark tests.
  • 138.5% higher power demand at 155W vs 65W.
  • Older platform position on TR4 with DDR4, while Core i5-12400F moves to LGA1700 and DDR5.
  • No boxed cooler included, unlike Core i5-12400F.

Quick Answers

So, is Core i5-12400F better than EPYC 7351?
Not in a simple one-size-fits-all way. EPYC 7351 makes more sense for workstation-style multi-core throughput, while Core i5-12400F is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, EPYC 7351 is the better fit. You are getting 18.9% better PassMark, backed by 16 cores and 32 threads. It also carries the larger cache pool with 255.6% larger total L3 cache (64 MB vs 18 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-12400F is the smarter buy today. Core i5-12400F is at an unclear MSRP at $174 MSRP versus unclear MSRP, and it gives you a 8.6% average FPS lead across 4 shared CPU game tests in our data. The trade-off is that EPYC 7351 is still stronger for heavier multi-core work with 18.9% better PassMark. It is also 100.0% better value on MSRP (112.3 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.
Which one is more future-proof for 2026 and beyond?
Core i5-12400F is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2017) and a healthier platform with LGA1700 and DDR5 instead of TR4. That should give you a better long-term upgrade path for motherboard, RAM, and future CPU swaps.

Games Benchmarks

Paired with RTX 4090

To accurately isolate CPU performance, all benchmarks below use an NVIDIA RTX 4090 as the reference GPU. This eliminates GPU-side bottlenecks and highlights pure processing throughput differences between the CPUs.

Note: Real-world results may vary based on your actual GPU. CPU performance impact is more visible in processing-intensive titles and high-refresh-rate gaming scenarios.
