Core i5-12400

2022

Why buy it

✅+125% larger total L3 cache (18 MB vs 8 MB).
✅Newer platform on LGA1700 with DDR5 support instead of FP6 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with UHD Graphics 730, while Ryzen 9 4900H needs a discrete GPU.
✅Includes a boxed cooler (Yes), unlike Ryzen 9 4900H.

Trade-offs

❌Lower PassMark (18,794 vs 18,887).
❌Launch MSRP is still $209 MSRP, while Ryzen 9 4900H mostly shows up through inconsistent older-market listings.
❌44.4% higher power demand at 65W vs 45W.

Ryzen 9 4900H

2020

Why buy it

Quick Answers

So, is Ryzen 9 4900H better than Core i5-12400?

Yes. Ryzen 9 4900H is the better all-around CPU here. It gives you a 2.1% average FPS lead across 50 shared CPU game tests in our data and 0.5% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

For gaming, this matchup is basically a tie in the data we have.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Ryzen 9 4900H is the stronger fit. You are getting 0.5% better PassMark, backed by 8 cores and 16 threads.

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

Ryzen 9 4900H is still the faster CPU overall, but Core i5-12400 is easier to justify if budget matters more than peak performance. Ryzen 9 4900H comes in at an unclear MSRP at unclear MSRP versus $209 MSRP, and it still gives you a 2.1% average FPS lead across 50 shared CPU game tests in our data. Core i5-12400 is also 100.0% better value on MSRP (89.9 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i5-12400 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2020), a healthier platform with LGA1700 and DDR5 instead of FP6, and 125% larger total L3 cache (18 MB vs 8 MB). That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
