Core i3-1315U vs Core i7-6850K: Pros, Cons & Final Verdict

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

Core i3-1315U

2023

Why buy it

  • Better for gaming: +6.6% higher average FPS across 50 shared CPU benchmark tests.
  • Draws 15W instead of 140W, a 125W reduction.
  • Newer platform on FCBGA1744 with DDR5 support instead of LGA2011 and DDR4.

Trade-offs

  • Lower PassMark (11,248 vs 11,376).
  • Smaller total L3 cache (10 MB vs 15 MB).

Core i7-6850K

2016

Why buy it

  • +1.1% higher PassMark.
  • +50% larger total L3 cache (15 MB vs 10 MB).
  • 100+% more PCIe lanes (40 vs 0) for storage and expansion-heavy builds.

Trade-offs

  • Worse for gaming: lower average FPS than Core i3-1315U across 50 shared CPU benchmark tests.
  • Launch MSRP is still $617 MSRP, while Core i3-1315U mostly shows up through inconsistent older-market listings.
  • 833.3% higher power demand at 140W vs 15W.
  • Older platform position on LGA2011 with DDR4, while Core i3-1315U moves to FCBGA1744 and DDR5.

Quick Answers

So, is Core i3-1315U better than Core i7-6850K?
It depends on what you want from the system. For gaming, Core i3-1315U is ahead with a 6.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-6850K pulls ahead with 1.1% better PassMark. Core i7-6850K also has the bigger cache pool with 50% larger total L3 cache (15 MB vs 10 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i7-6850K is the stronger fit. You are getting 1.1% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (15 MB vs 10 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Core i3-1315U is still the much better call for a fresh build. Core i3-1315U comes in at an unclear MSRP at unclear MSRP versus $617 MSRP, and it still gives you a 6.6% average FPS lead across 50 shared CPU game tests in our data. Core i7-6850K only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2016 platform. Even with 100.0% better value on paper (18.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA2011.
Which one is more future-proof for 2026 and beyond?
Core i3-1315U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2016) and a healthier platform with FCBGA1744 and DDR5 instead of LGA2011. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
