Quick Answers

So, is Ryzen 7 3700U better than Core i7-6820HK?

Yes. Ryzen 7 3700U is the better all-around CPU here. It gives you a 6.1% average FPS lead across 50 shared CPU game tests in our data, 0.5% 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, Ryzen 7 3700U is the better pick. According to our tests, it delivers 6.1% 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, Ryzen 7 3700U is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 8 threads.

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

Ryzen 7 3700U is the easy recommendation for a fresh desktop build. Ryzen 7 3700U comes in at an unclear MSRP at unclear MSRP versus $378 MSRP, and it still gives you a 6.1% average FPS lead across 50 shared CPU game tests in our data. Core i7-6820HK only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 6.1% in the shared gaming data.

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

Ryzen 7 3700U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2015) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
