Core i5-8250U vs Core i7-8550U: Pros, Cons & Final Verdict

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

Core i5-8250U

2017

Why buy it

  • +0.7% higher PassMark.
  • 100+% more PCIe lanes (12 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 620, while Core i7-8550U needs a discrete GPU.

Trade-offs

  • Smaller total L3 cache (6 MB vs 8 MB).

Core i7-8550U

2017

Why buy it

  • +33.3% larger total L3 cache (8 MB vs 6 MB).

Trade-offs

  • Lower PassMark (6,118 vs 6,158).
  • No integrated graphics, while Core i5-8250U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i5-8250U better than Core i7-8550U?
It depends on what you want from the system. For gaming, Core i7-8550U is ahead with a 2.2% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-8250U pulls ahead with 0.7% better PassMark. Core i7-8550U also has the bigger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-8250U is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-8250U still makes the most sense overall. Core i5-8250U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.7% better PassMark.
Which one is more future-proof for 2026 and beyond?
Core i5-8250U makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
