Quick Answers

So, is Core i9-12900E better than Ryzen 7 3700X?

Yes. Core i9-12900E 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, 25.6% 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, Core i9-12900E is the better pick. According to our tests, it delivers 2.1% 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, Core i9-12900E is the stronger fit. You are getting 25.6% better PassMark, backed by 16 cores and 24 threads.

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

Core i9-12900E is still the faster CPU overall, but Ryzen 7 3700X is easier to justify if budget matters more than peak performance. Core i9-12900E comes in 52.0% more expensive on MSRP at $500 MSRP versus $329 MSRP, and it still gives you a 2.1% average FPS lead across 50 shared CPU game tests in our data. Ryzen 7 3700X is also 21.0% better value on MSRP (68.2 vs 56.3 PassMark/$), which is why it can still make sense for tighter-budget builds on paper. That said, if you already own a compatible AM4 + DDR4 setup, Ryzen 7 3700X 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 i9-12900E makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2022 vs 2019), a healthier platform with LGA1700 and DDR5 instead of AM4, and more multi-core headroom with 16 cores / 24 threads instead of 8/16. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
