Core i5-8600K vs Core i7-8850H: Pros, Cons & Final Verdict

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

Core i5-8600K

2017

Why buy it

  • +0.6% higher PassMark.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 630, while Core i7-8850H needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-8850H across 50 shared CPU benchmark tests.
  • Smaller total L3 cache (9 MB vs 12 MB).
  • Launch MSRP is still $257 MSRP, while Core i7-8850H mostly shows up through inconsistent older-market listings.
  • 111.1% higher power demand at 95W vs 45W.

Core i7-8850H

2018

Why buy it

  • Better for gaming: +10.0% higher average FPS across 50 shared CPU benchmark tests.
  • +33.3% larger total L3 cache (12 MB vs 9 MB).
  • Draws 45W instead of 95W, a 50W reduction.

Trade-offs

  • Lower PassMark (10,074 vs 10,134).
  • No integrated graphics, while Core i5-8600K can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-8850H better than Core i5-8600K?
It depends on what you want from the system. For gaming, Core i7-8850H is ahead with a 10.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-8600K pulls ahead with 0.6% better PassMark. Core i7-8850H also has the bigger cache pool with 33.3% larger total L3 cache (12 MB vs 9 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-8600K is the stronger fit. You are getting 0.6% better PassMark, backed by 6 cores and 6 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-8850H is still the much better call for a fresh build. Core i7-8850H comes in at an unclear MSRP at unclear MSRP versus $257 MSRP, and it still gives you a 10.0% average FPS lead across 50 shared CPU game tests in our data. Core i5-8600K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (39.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.
Which one is more future-proof for 2026 and beyond?
Core i7-8850H makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2017) and 33.3% larger total L3 cache (12 MB vs 9 MB). That makes it the safer long-term bet.
