Core Ultra 9 275HX vs EPYC 7401: Pros, Cons & Final Verdict

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

Core Ultra 9 275HX

2025

Why buy it

  • Better for gaming: +32.1% higher average FPS across 50 shared CPU benchmark tests.
  • Draws 55W instead of 155W, a 100W reduction.
  • Newer platform on FCBGA2114 with DDR5 support instead of TR4 and DDR4.
  • Integrated graphics onboard with Intel Arc Graphics, while EPYC 7401 needs a discrete GPU.

Trade-offs

  • Smaller total L3 cache (36 MB vs 64 MB).
  • Less compelling for workstation-style loads than EPYC 7401, which brings 24 cores / 48 threads and 128 PCIe lanes.

EPYC 7401

2017

Why buy it

  • +77.8% larger total L3 cache (64 MB vs 36 MB).
  • Better for workstations and heavier parallel workloads: 24 cores / 48 threads, plus 128 PCIe lanes vs 24.
  • 433.3% more PCIe lanes (128 vs 24) for storage and expansion-heavy builds.

Trade-offs

  • Worse for gaming: lower average FPS than Core Ultra 9 275HX across 50 shared CPU benchmark tests.
  • Lower PassMark (55,280 vs 56,018).
  • Launch MSRP is still $1,500 MSRP, while Core Ultra 9 275HX mostly shows up through inconsistent older-market listings.
  • 181.8% higher power demand at 155W vs 55W.
  • Older platform position on TR4 with DDR4, while Core Ultra 9 275HX moves to FCBGA2114 and DDR5.

Quick Answers

So, is Core Ultra 9 275HX better than EPYC 7401?
Not really, because they are built for different jobs. EPYC 7401 makes more sense for workstation-style multi-core throughput, while Core Ultra 9 275HX is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for gaming?
If gaming is the priority, Core Ultra 9 275HX is the better pick. According to our tests, it delivers 32.1% 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 Ultra 9 275HX is the stronger fit. You are getting 1.3% better PassMark, backed by 24 cores and 24 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core Ultra 9 275HX is still the faster CPU overall, but EPYC 7401 is easier to justify if budget matters more than peak performance. Core Ultra 9 275HX comes in at an unclear MSRP at unclear MSRP versus $1,500 MSRP, and it still gives you a 32.1% average FPS lead across 50 shared CPU game tests in our data. EPYC 7401 is also 100.0% better value on MSRP (36.9 vs 0.0 PassMark/$), 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 Ultra 9 275HX makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2017), a healthier platform with FCBGA2114 and DDR5 instead of TR4, and more multi-core headroom with 24 cores / 24 threads instead of 24/48. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
