Core i7-8665UE

2018

Why buy it

✅Better for gaming: +13.7% higher average FPS across 50 shared CPU benchmark tests.
✅+33.3% larger total L3 cache (8 MB vs 6 MB).
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 620, while N250 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $409 MSRP, while N250 mostly shows up through inconsistent older-market listings.
❌Older platform position on FCBGA1528 with DDR4, while N250 moves to FCBGA1264 and DDR5.

N250

2025

Why buy it

✅Newer platform on FCBGA1264 with DDR5 support instead of FCBGA1528 and DDR4.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-8665UE across 50 shared CPU benchmark tests.
❌Lower PassMark (4,773 vs 4,852).
❌Smaller total L3 cache (6 MB vs 8 MB).
❌No integrated graphics, while Core i7-8665UE can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-8665UE better than N250?

Yes. Core i7-8665UE is the better all-around CPU here. It gives you a 13.7% average FPS lead across 50 shared CPU game tests in our data and 1.7% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-8665UE is the better pick. According to our tests, it delivers 13.7% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i7-8665UE is the stronger fit. You are getting 1.7% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

Which one is the smarter buy today, not just the cheaper CPU?

Core i7-8665UE is the better buy right now. Core i7-8665UE comes in at an unclear MSRP at $409 MSRP versus unclear MSRP, and it still gives you a 13.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (11.9 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

Which one is more future-proof for 2026 and beyond?

N250 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2018) and a healthier platform with FCBGA1264 and DDR5 instead of FCBGA1528. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
