Quick Answers

So, is Core i7-1355U better than Core i5-10600KF?

It depends on what you want from the system. For gaming, Core i7-1355U is ahead with a 7.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-10600KF pulls ahead with 0.2% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-10600KF is the stronger fit. You are getting 0.2% better PassMark, backed by 6 cores and 12 threads.

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

Core i7-1355U is still the faster CPU overall, but Core i5-10600KF is easier to justify if budget matters more than peak performance. Core i7-1355U comes in at an unclear MSRP at unclear MSRP versus $250 MSRP, and it still gives you a 7.1% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-10600KF is still stronger for heavier multi-core work with 0.2% better PassMark. Core i5-10600KF is also 100.0% better value on MSRP (56.6 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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 a newer CPU generation (2023 vs 2020) and a healthier platform with FCBGA1744 and DDR5 instead of LGA1200. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
