Quick Answers

So, is Ryzen 7 5700X better than Pentium G840?

Yes. Ryzen 7 5700X is the better all-around CPU here. It gives you a 631.9% average FPS lead across 50 shared CPU game tests in our data, 1846.5% 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 5700X is the better pick. According to our tests, it delivers 631.9% 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 1846.5% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 966.7% larger total L3 cache (32 MB vs 3 MB).

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 367.2% more expensive on MSRP at $299 MSRP versus $64 MSRP, and it still gives you a 631.9% average FPS lead across 50 shared CPU game tests in our data. It is also 316.6% better value on MSRP (89.0 vs 21.4 PassMark/$), 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 2011), 966.7% larger total L3 cache (32 MB vs 3 MB), and more multi-core headroom with 8 cores / 16 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
