Core i9-9900KS vs EPYC 7252: Pros, Cons & Final Verdict

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

Core i9-9900KS

2019

Why buy it

  • Better for gaming: +28.1% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

  • Lower PassMark (19,397 vs 19,411).
  • Smaller total L3 cache (16 MB vs 32 MB).
  • Launch MSRP is still $513 MSRP, while EPYC 7252 mostly shows up through inconsistent older-market listings.

EPYC 7252

2019

Why buy it

  • +0.1% higher PassMark.
  • +100% larger total L3 cache (32 MB vs 16 MB).
  • Draws 120W instead of 127W, a 7W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Core i9-9900KS across 50 shared CPU benchmark tests.

Quick Answers

So, is EPYC 7252 better than Core i9-9900KS?
Not really, because they are built for different jobs. EPYC 7252 makes more sense for workstation-style multi-core throughput, while Core i9-9900KS is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, EPYC 7252 is the stronger fit. You are getting 0.1% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 100% larger total L3 cache (32 MB vs 16 MB).
Which one is the smarter buy today, not just the cheaper CPU?
EPYC 7252 is still the faster CPU overall, but Core i9-9900KS is easier to justify if budget matters more than peak performance. EPYC 7252 comes in at an unclear MSRP at unclear MSRP versus $513 MSRP, and it still gives you 0.1% better PassMark. The compromise is that Core i9-9900KS is still the better pure gaming CPU with a 28.1% average FPS lead across 50 shared CPU game tests in our data. Core i9-9900KS is also 100.0% better value on MSRP (37.8 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.
Which one is more future-proof for 2026 and beyond?
EPYC 7252 makes more sense long term for 2026 and beyond. You are getting 100% larger total L3 cache (32 MB vs 16 MB) and more multi-core headroom with 8 cores / 16 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
