Quick Answers

So, is Core i5-1235U better than Core i7-10700T?

It depends on what you want from the system. For gaming, Core i5-1235U is ahead with a 6.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-10700T pulls ahead with 1.2% better PassMark. Core i7-10700T also has the bigger cache pool with 33.3% larger total L3 cache (16 MB vs 12 MB).

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

For streaming, content creation, and heavier multitasking, Core i7-10700T is the stronger fit. You are getting 1.2% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 33.3% larger total L3 cache (16 MB vs 12 MB).

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

Core i5-1235U is still the faster CPU overall, but Core i7-10700T is easier to justify if budget matters more than peak performance. Core i5-1235U comes in at an unclear MSRP at unclear MSRP versus $355 MSRP, and it still gives you a 6.7% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i7-10700T is still stronger for heavier multi-core work with 1.2% better PassMark. Core i7-10700T is also 100.0% better value on MSRP (36.3 vs 0.0 PassMark/$), 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 i5-1235U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 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.
