Quick Answers

So, is Core i3-4150 better than Core 2 Duo T5670?

It depends on what you want from the system. For gaming, Core i3-4150 is ahead with a 11.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core 2 Duo T5670 pulls ahead with 1% better PassMark. Core i3-4150 also has the bigger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Core 2 Duo T5670 is the stronger fit. You are getting 1% better PassMark, backed by 2 cores and 2 threads.

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

Core i3-4150 is the better buy right now. Core i3-4150 comes in at an unclear MSRP at $281 MSRP versus unclear MSRP, and it still gives you a 11.1% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core 2 Duo T5670 is still stronger for heavier multi-core work with 1% better PassMark. It is also 100.0% better value on MSRP (12.1 vs 0.0 PassMark/$), 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 i3-4150 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2008) and 50% larger total L3 cache (3 MB vs 2 MB). That makes it the safer long-term bet.
