Quick Answers

So, is Core i7-1355U better than Ryzen 3 PRO 5355G?

Yes. Core i7-1355U is the better all-around CPU here. It gives you a 29.1% average FPS lead across 50 shared CPU game tests in our data, 0.6% 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 29.1% 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 0.6% better PassMark, backed by 10 cores and 12 threads. It also has the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

Core i7-1355U is still the faster CPU overall, but Ryzen 3 PRO 5355G is easier to justify if budget matters more than peak performance. Core i7-1355U comes in at an unclear MSRP at unclear MSRP versus $130 MSRP, and it still gives you a 29.1% average FPS lead across 50 shared CPU game tests in our data. Ryzen 3 PRO 5355G is also 100.0% better value on MSRP (107.9 vs 0.0 PassMark/$), 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 healthier platform with FCBGA1744 and DDR5 instead of AM4, 50% larger total L3 cache (12 MB vs 8 MB), and more multi-core headroom with 10 cores / 12 threads instead of 4/8. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
