Quick Answers

So, is Core i3-4150T better than Core i7-3520M?

It depends on what you want from the system. For gaming, Core i7-3520M is ahead with a 1.4% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i3-4150T pulls ahead with 1.8% better PassMark. Core i7-3520M also has the bigger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

For streaming, content creation, and heavier multitasking, Core i3-4150T is the stronger fit. You are getting 1.8% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-4150T is the better buy right now. Core i3-4150T comes in $229 cheaper on MSRP at $117 MSRP versus $346 MSRP, and it still gives you 1.8% better PassMark. The compromise is that Core i7-3520M is still the better pure gaming CPU with a 1.4% average FPS lead across 50 shared CPU game tests in our data. It is also 200.9% better value on MSRP (24.7 vs 8.2 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i3-4150T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2012) and more multi-core headroom with 2 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
