Core i7-9700K vs Core Ultra 5 115U: Pros, Cons & Final Verdict

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

Core i7-9700K

2018

Why buy it

  • Better for gaming: +44.0% higher average FPS across 50 shared CPU benchmark tests.
  • +20% larger total L3 cache (12 MB vs 10 MB).
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 630, while Core Ultra 5 115U needs a discrete GPU.

Trade-offs

  • Launch MSRP is still $385 MSRP, while Core Ultra 5 115U mostly shows up through inconsistent older-market listings.
  • Older platform position on LGA1151 with DDR4, while Core Ultra 5 115U moves to FCBGA2049 and DDR5.

Core Ultra 5 115U

2023

Why buy it

  • Newer platform on FCBGA2049 with DDR5 support instead of LGA1151 and DDR4.

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-9700K across 50 shared CPU benchmark tests.
  • Lower PassMark (11,518 vs 14,397).
  • Smaller total L3 cache (10 MB vs 12 MB).
  • No integrated graphics, while Core i7-9700K can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-9700K better than Core Ultra 5 115U?
Yes. Core i7-9700K is the better all-around CPU here. It gives you a 44.0% average FPS lead across 50 shared CPU game tests in our data and 25% better PassMark, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core i7-9700K is the better pick. According to our tests, it delivers 44.0% more average FPS across 50 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
