Quick Answers

So, is Core i3-8145U better than Core i7-2670QM?

It depends on what you want from the system. For gaming, Core i7-2670QM is ahead with a 11.6% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-8145U pulls ahead with 0.9% better PassMark. Core i7-2670QM also has the bigger cache pool with 50% larger total L3 cache (6 MB vs 4 MB).

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

For streaming, content creation, and heavier multitasking, Core i3-8145U is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-8145U still makes the most sense overall. Core i3-8145U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.9% better PassMark.

Which one is more future-proof for 2026 and beyond?

Core i3-8145U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2011) and more multi-core headroom with 2 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
