Quick Answers

So, is Atom C3708 better than Core i5-7287U?
Yes. Atom C3708 is the better all-around CPU here. It gives you a 17.7% average FPS lead across 50 shared CPU game tests in our data, 0.2% 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, Atom C3708 is the better pick. According to our tests, it delivers 17.7% 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, Atom C3708 is the stronger fit. You are getting 0.2% better PassMark, backed by 8 cores and 8 threads. It also has the larger cache pool with 300% larger total L3 cache (16 MB vs 4 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Atom C3708 still makes the most sense overall. Atom C3708 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 17.7% average FPS lead across 50 shared CPU game tests in our data.
Which one is more future-proof for 2026 and beyond?
Atom C3708 makes more sense long term for 2026 and beyond. You are getting 300% larger total L3 cache (16 MB vs 4 MB) and more multi-core headroom with 8 cores / 8 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
