Quick Answers

So, is Core i7-1355U better than Core i5-1335U?

Yes. Core i7-1355U is the better all-around CPU here. It gives you a 6.2% average FPS lead across 50 shared CPU game tests in our data, 0.2% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-1355U is the better pick. According to our tests, it delivers 6.2% 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 i7-1355U is the stronger fit. You are getting 0.2% better PassMark, backed by 10 cores and 12 threads.

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

Core i7-1355U still makes the most sense overall. Core i7-1355U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 6.2% average FPS lead across 50 shared CPU game tests in our data.

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

Core i7-1355U makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 10 cores / 12 threads instead of 10/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
