Quick Answers

So, is Core i7-1355U better than Core i9-10900TE?

It depends on what you want from the system. For gaming, Core i7-1355U is ahead with a 18.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i9-10900TE pulls ahead with 0.3% better PassMark. Core i9-10900TE also has the bigger cache pool with 66.7% larger total L3 cache (20 MB vs 12 MB).

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

For streaming, content creation, and heavier multitasking, Core i9-10900TE is the stronger fit. You are getting 0.3% better PassMark, backed by 10 cores and 20 threads. It also has the larger cache pool with 66.7% larger total L3 cache (20 MB vs 12 MB).

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

Core i7-1355U is still the faster CPU overall, but Core i9-10900TE is easier to justify if budget matters more than peak performance. Core i7-1355U comes in at an unclear MSRP at unclear MSRP versus $309 MSRP, and it still gives you a 18.1% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i9-10900TE is still stronger for heavier multi-core work with 0.3% better PassMark. Core i9-10900TE is also 100.0% better value on MSRP (45.8 vs 0.0 PassMark/$), 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.
