Quick Answers

So, is Core i7-3687U better than Core i5-4258U?

Yes. Core i7-3687U is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data, 0.4% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-3687U is the better pick. According to our tests, it delivers 0.2% 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 i7-3687U is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 4 threads. It also has the larger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

Core i7-3687U still makes the most sense overall. Core i7-3687U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data.

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

Core i7-3687U makes more sense long term for 2026 and beyond. You are getting 33.3% larger total L3 cache (4 MB vs 3 MB) 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.
