Quick Answers

So, is Ryzen 7 5700X better than Atom x5-E3940?

Yes. Ryzen 7 5700X is the better all-around CPU here. It gives you a 452.7% average FPS lead across 50 shared CPU game tests in our data, 1365.3% 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 5700X is the better pick. According to our tests, it delivers 452.7% 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, Ryzen 7 5700X is the stronger fit. You are getting 1365.3% better PassMark, backed by 8 cores and 16 threads.

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

Ryzen 7 5700X is the better buy right now. Ryzen 7 5700X comes in at an unclear MSRP at $299 MSRP versus unclear MSRP, and it still gives you a 452.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (89.0 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Ryzen 7 5700X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2014) and more multi-core headroom with 8 cores / 16 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
