Quick Answers

So, is Core i3-4370T better than Core i5-4340M?

It depends on what you want from the system. For gaming, Core i3-4370T is ahead with a 5.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-4340M pulls ahead with 0.6% better PassMark. Core i3-4370T 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 i5-4340M is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 4 threads.

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

Core i3-4370T is the better buy right now. Core i3-4370T comes in at an unclear MSRP at $138 MSRP versus unclear MSRP, and it still gives you a 5.1% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-4340M is still stronger for heavier multi-core work with 0.6% better PassMark. It is also 100.0% better value on MSRP (24.4 vs 0.0 PassMark/$), 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 i3-4370T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2014) and 33.3% larger total L3 cache (4 MB vs 3 MB). That makes it the safer long-term bet.
