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

Core i5-10600K

2020

Why buy it

✅+0.9% higher PassMark.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics 630, while Core i7-1355U needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-1355U across 50 shared CPU benchmark tests.
❌Launch MSRP is still $262 MSRP, while Core i7-1355U mostly shows up through inconsistent older-market listings.
❌733.3% higher power demand at 125W vs 15W.
❌Older platform position on LGA1200 with DDR4, while Core i7-1355U moves to FCBGA1744 and DDR5.

Core i7-1355U

2023

Why buy it

✅Better for gaming: +6.9% higher average FPS across 50 shared CPU benchmark tests.
✅Draws 15W instead of 125W, a 110W reduction.
✅Newer platform on FCBGA1744 with DDR5 support instead of LGA1200 and DDR4.

Trade-offs

❌Lower PassMark (14,116 vs 14,247).
❌No integrated graphics, while Core i5-10600K can still boot and troubleshoot without a discrete GPU.

Quick Answers

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

It depends on what you want from the system. For gaming, Core i7-1355U is ahead with a 6.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-10600K pulls ahead with 0.9% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-10600K is the stronger fit. You are getting 0.9% 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 i5-10600K is easier to justify if budget matters more than peak performance. Core i7-1355U comes in at an unclear MSRP at unclear MSRP versus $262 MSRP, and it still gives you a 6.9% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-10600K is still stronger for heavier multi-core work with 0.9% better PassMark. Core i5-10600K is also 100.0% better value on MSRP (54.4 vs 0.0 PassMark/$), 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.
