Quick Answers

So, is Core i7-3840QM better than Core i5-7600T?

Yes. Core i7-3840QM is the better all-around CPU here. It gives you a 14.7% average FPS lead across 50 shared CPU game tests in our data and 0.8% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-3840QM is the better pick. According to our tests, it delivers 14.7% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core i7-3840QM is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Core i7-3840QM is still the much better call for a fresh build. Core i7-3840QM comes in at an unclear MSRP at unclear MSRP versus $192 MSRP, and it still gives you a 14.7% average FPS lead across 50 shared CPU game tests in our data. Core i5-7600T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 100.0% better value on paper (30.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Core i5-7600T makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2012). That makes it the safer long-term bet.
