Quick Answers

So, is Ryzen 7 5800X better than Core 5 120?

Yes. Ryzen 7 5800X is the better all-around CPU here. It gives you a 25.1% average FPS lead across 50 shared CPU game tests in our data and 28.1% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Ryzen 7 5800X is the better pick. According to our tests, it delivers 25.1% 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 5800X is the stronger fit. You are getting 28.1% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 77.8% larger total L3 cache (32 MB vs 18 MB).

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

Ryzen 7 5800X is still the faster CPU overall, but Core 5 120 is easier to justify if budget matters more than peak performance. Ryzen 7 5800X comes in 32.1% more expensive on MSRP at $449 MSRP versus $340 MSRP, and it still gives you a 25.1% average FPS lead across 50 shared CPU game tests in our data. Core 5 120 is also 3.1% better value on MSRP (63.6 vs 61.7 PassMark/$), which is why it can still make sense for tighter-budget builds on paper. That said, if you already own a compatible LGA1700 + DDR5 setup, Core 5 120 can still make sense as a platform-matched option because it avoids a motherboard and RAM swap.

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

Core 5 120 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2025 vs 2020) and a healthier platform with LGA1700 and DDR5 instead of AM4. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
