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 i7-13700K

2022

Why buy it

  • Better for gaming: +21.2% higher average FPS across 50 shared CPU benchmark tests.
  • Draws 125W instead of 180W, a 55W 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.
  • Integrated graphics onboard with Intel UHD Graphics 770, while EPYC 7451 needs a discrete GPU.

Trade-offs

  • Smaller total L3 cache (30 MB vs 64 MB).
  • Less compelling for workstation-style loads than EPYC 7451, which brings 24 cores / 48 threads.
  • Launch MSRP is still $409 MSRP, while EPYC 7451 mostly shows up through inconsistent older-market listings.

EPYC 7451

2017

Why buy it

  • +113.3% larger total L3 cache (64 MB vs 30 MB).
  • Better for workstations and heavier parallel workloads: 24 cores / 48 threads.

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-13700K across 50 shared CPU benchmark tests.
  • Lower PassMark (26,639 vs 45,784).
  • 44% higher power demand at 180W vs 125W.
  • Older platform position on TR4 with DDR4, while Core i7-13700K moves to LGA1700 and DDR5.
  • No integrated graphics, while Core i7-13700K can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-13700K better than EPYC 7451?
Not in a simple one-size-fits-all way. EPYC 7451 makes more sense for workstation-style multi-core throughput, while Core i7-13700K is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.
Which one is better for gaming?
If gaming is the priority, Core i7-13700K is the better pick here. According to our tests, it delivers 21.2% 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 i7-13700K is the better fit. You are getting 71.9% better PassMark, backed by 16 cores and 24 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-13700K is the smarter buy today. Core i7-13700K is at an unclear MSRP at $409 MSRP versus unclear MSRP, and it gives you a 21.2% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (111.9 vs 0.0 PassMark/$), 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 i7-13700K is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2017), a healthier platform with LGA1700 and DDR5 instead of TR4, and more multi-core headroom with 16 cores / 24 threads instead of 24/48. 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.
