Community Feedback
What Owners Say
Owners love the fast single-core performance for gaming, but hate the high power draw that makes it run hot and need a beefy cooler.
Pros
- Plays modern games without bottlenecking
- Stays cool in small cases
- Handles heavy multitasking comfortably
- Sips power for an i9
Cons
- Not a big upgrade from last gen
- Requires new motherboard for small gains
- Runs hot with the stock cooler
Verdict
Our verdict on the Core i9-11900
An eight-core Rocket Lake desktop chip that runs cool and quiet but trails its AMD rival in multi-threaded work.
Get it if you need a solid upgrade for an older LGA1200 board and care more about low power draw than raw speed. Skip it if you want maximum performance for gaming or heavy workloads, as cheaper options often beat it.
Buy it if…
- Buy it if you need a cool-running office PC upgrade.
- Buy it if you want stable performance in a small prebuilt.
- Buy it if you're on a tight budget for a basic work desktop.
