Quick Answers

So, is Ryzen 5 5600X better than Core i7-3840QM?
Yes. Ryzen 5 5600X is the better all-around CPU here. It gives you a 80.8% average FPS lead across 50 shared CPU game tests in our data, 272.1% 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 5 5600X is the better pick. According to our tests, it delivers 80.8% 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 5 5600X is the stronger fit. You are getting 272.1% better PassMark, backed by 6 cores and 12 threads. It also has the larger cache pool with 300% larger total L3 cache (32 MB vs 8 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Ryzen 5 5600X is the better buy right now. Ryzen 5 5600X comes in at an unclear MSRP at $299 MSRP versus unclear MSRP, and it still gives you a 80.8% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (73.1 vs 0.0 PassMark/$), 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 5 5600X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2012), 300% larger total L3 cache (32 MB vs 8 MB), and more multi-core headroom with 6 cores / 12 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
